FJINNO's fiber optic temperature sensing technology works on the principle of fluorescence decay. The system sends light pulses through an optical fiber to a phosphor sensor tip installed at the measurement point. The phosphor material absorbs this light and emits fluorescence. When the excitation light is switched off, the fluorescence continues to emit but gradually decays.

The key scientific principle is that this decay time (fluorescence lifetime) varies precisely with temperature—higher temperatures result in shorter decay times. By accurately measuring this decay time, our system determines the exact temperature at the sensor location. This measurement principle depends only on the time characteristic, not signal intensity, making it immune to fiber bending, connector losses, or light source variations.

FJINNO's fiber optic sensors are completely immune to electromagnetic interference (EMI) due to their all-optical design with no metallic components. The sensors consist of:

• Pure quartz optical fibers that transmit light signals without using electrical conductors
• Non-metallic phosphor sensing elements that operate purely on optical principles
• Dielectric materials for all sensor construction including protective coverings

Unlike conventional sensors that use electrical signals (which can be disturbed by magnetic fields), our fiber optic sensors transmit only light signals. Even in extreme environments with high-voltage equipment, powerful electromagnetic fields, or electrical transients, the measurement remains completely unaffected. This immunity is particularly crucial in electrical equipment applications where intense magnetic fields from high currents can cause significant measurement errors in conventional sensors.

FJINNO's standard fiber optic temperature sensors offer a temperature measurement range of -40°C to +260°C with an accuracy of ±1°C and a resolution of 0.1°C. This range covers the vast majority of electrical equipment monitoring applications, from ambient temperatures in cold regions to the highest hotspot temperatures typically encountered in electrical equipment under fault conditions.

For specialized applications, we offer custom-engineered solutions with extended temperature ranges. Our research and development team can design custom sensors for applications requiring measurements up to 300°C or higher while maintaining high accuracy. Each sensor is individually calibrated across its entire operating range to ensure precision measurements throughout its lifetime.

FJINNO fiber optic temperature sensors offer industry-leading performance specifications:

• Accuracy: ±1°C across the entire measurement range (higher accuracy options available for specialized applications)
• Resolution: 0.1°C allowing detection of minute temperature changes
• Response time: Less than 1 second to full reading, significantly faster than conventional temperature sensors
• Measurement cycle: Typically 200-500ms per channel, enabling near real-time monitoring of multiple points

The fast response time is particularly valuable for detecting rapidly developing thermal events in electrical equipment. Unlike conventional sensors that may have significant thermal mass and slow response, our fiber optic sensors can detect temperature changes almost immediately, providing crucial early warning of developing issues.

FJINNO offers flexible monitoring solutions to accommodate various application requirements:

• Standard systems can monitor from 1 to 64 independent temperature points
• Our IF-DK series supports up to 18 channels for reactor applications
• The polycrystalline silicon transformer monitoring system combines 24 PT100 channels with 3 fiber optic channels
• Box-type substation systems typically monitor 6 critical points (3 circuit breaker contacts, 3 cable joints)

For larger installations requiring more measurement points, multiple analyzer units can be networked together to create comprehensive monitoring systems covering hundreds of measurement points across a facility. Each temperature point maintains full accuracy regardless of the total number of channels being monitored. Our system architecture uses time-division multiplexing to scan all channels efficiently while maintaining measurement integrity.

FJINNO fiber optic temperature monitoring systems are versatile and can be applied to virtually any type of electrical equipment, including:

• Transformers: Both oil-immersed and dry-type transformers, including specialized types like polycrystalline silicon transformers

• Switchgear: Medium and high-voltage switchgear, including GIS (Gas Insulated Switchgear)
• Busbar systems: Rigid busbars, flexible connections, and busbar joints
• Box-type substations: Compact integrated substations with transformers and switchgear
• Cable systems: Cable joints, terminations, and critical sections of power cables
• Circuit breakers: Moving and fixed contacts in various types of breakers
• Motors and generators: Windings, bearings, and terminal connections

Our engineering team works closely with clients to identify the optimal monitoring points for each specific equipment type and application scenario.

The most critical temperature monitoring points in electrical equipment typically include:

• Transformer/Reactor Windings: Hotspot locations in windings where the highest temperatures typically occur

• Cooling Ducts: Critical points in cooling passages to verify cooling effectiveness

FJINNO's application engineers conduct thermal analysis to identify the optimal monitoring locations for each specific equipment type. For critical equipment, we often recommend monitoring multiple points to create a comprehensive thermal profile.

FJINNO's fiber optic temperature sensors can be installed in both new equipment and retrofitted to existing equipment:

• New Equipment Installation: For optimal results, sensors can be integrated during manufacturing, allowing placement at internal hotspots such as within transformer windings or internal components of switchgear.
• Retrofit Installation: Existing equipment can be fitted with sensors during planned maintenance outages. The compact sensor size and flexible fiber optic cables make retrofit installation practical for most equipment types.

For retrofit applications, our engineering team assesses the equipment to determine the most effective sensor placement options based on accessibility and critical thermal zones. In many cases, sensors can be installed at critical connection points without major disassembly of the equipment. For example, in switchgear applications, sensors can often be installed at accessible busbar joints and cable terminations.

We've successfully retrofit hundreds of existing installations, with equipment ranging from a few years to decades old.

FJINNO fiber optic sensors are installed using several methods depending on the application and equipment type:

• Direct Contact Mounting: Sensors are placed in direct thermal contact with the surface to be monitored using thermal epoxy or mechanical fixtures that ensure good thermal coupling.
• Embedded Installation: In new equipment, sensors can be embedded within windings or components during manufacturing.
• Retrofit Attachment: Special mounting brackets and thermal coupling compounds allow secure attachment to existing equipment surfaces.
• Cable Management: The fiber optic cables are securely routed and protected using appropriate cable management systems such as flexible conduit or cable trays.

The installation process is non-invasive and does not affect the electrical integrity of the equipment. The small sensor size (standard 2.5mm diameter, with smaller options available) allows placement in confined spaces. Fiber optic cables can be routed through existing wireways or conduits to the monitoring unit located in an accessible area.

For specialized applications like oil-immersed transformers, we provide oil-resistant sensors and appropriate feedthrough solutions to maintain the integrity of the tank.

FJINNO's standard fiber optic temperature measurement systems can accommodate the following distances:

• Standard sensor configurations: Up to 20 meters between the sensor tip and the monitoring unit
• Extended configurations: Up to 100 meters with specialized fiber optic extensions and signal boosting

This flexibility allows the monitoring unit to be placed in an accessible, controlled environment while sensors are positioned at remote locations within electrical equipment. Unlike conventional sensors that may experience signal degradation or noise pickup over long distances, fiber optic sensors maintain full accuracy regardless of the cable length.

For large installations or campus environments, multiple monitoring units can be networked together and connected to a centralized monitoring system, allowing temperature data to be collected from equipment throughout the facility.

FJINNO monitoring systems offer comprehensive alarm and notification features:

• Multi-level Temperature Alarms: Configurable warning and critical alarm thresholds for each monitored point

  • Ethernet/IP
  • DNP3

For integration with SCADA systems, the Modbus register map is fully documented, allowing system integrators to configure data acquisition for all temperature points and alarm status information. The system can be configured as a Modbus slave device with a unique address, allowing it to share a communications network with other equipment.

Our engineering team can provide support for integration projects, including custom protocol implementations if required for specific control systems.

FJINNO monitoring systems include sophisticated cooling system control capabilities:

• Automatic Fan Control: Temperature-based activation of cooling fans or pumps based on configurable setpoints

• Data Export: Ability to export historical data for external analysis
• Advanced Analytics: Optional software for trend analysis, pattern recognition, and predictive maintenance
• Cloud Integration: Optional connection to cloud platforms for long-term data storage and advanced analytics

The historical data is invaluable for several purposes:

• Analyzing equipment thermal behavior under various load conditions
• Identifying gradual deterioration trends that might indicate developing issues
• Correlating temperature patterns with operational events or environmental conditions
• Supporting condition-based maintenance decisions with objective data
• Documenting equipment thermal performance for regulatory compliance

This historical record creates a complete thermal profile of the equipment over its operational life, providing insights that would be impossible with periodic manual measurements or inspections.

Temperature alarm thresholds are determined through a systematic approach considering multiple factors:

• Manufacturer Specifications: Equipment manufacturer's temperature limits for components
• Industry Standards: IEEE, IEC, or other applicable standards for equipment temperature limits
• Insulation Class: Temperature limits based on the insulation materials used (particularly important for transformers)
• Baseline Analysis: Establishing normal operating temperature profiles during commissioning
• Operational Experience: Adjustments based on observed equipment behavior
• Thermal Modeling: Computer simulation to identify appropriate limits for specific equipment

Typically, we implement a multi-level alarm approach:

• Warning Level: Set at 10-15°C below the critical limit, providing early notification of abnormal temperatures
• Alarm Level: Set at 5-10°C below the critical limit, indicating a situation requiring prompt attention
• Trip Level: Set at the critical limit where equipment should be de-energized to prevent damage

For rate-of-rise alarms, thresholds are typically set between 1-3°C per minute sustained for a defined period, as rapid temperature increases often indicate developing faults even before absolute temperature limits are reached.

Our engineering team works with clients to establish appropriate thresholds during system commissioning, with provisions for seasonal adjustments if required.

FJINNO fiber optic temperature sensors provide exceptional high voltage isolation capabilities:

• Standard Sensor Isolation: 100kV dielectric strength
• Testing Verification: Sensors have been tested according to IEC standards for dielectric strength
• Partial Discharge Immunity: No susceptibility to partial discharge effects
• Inherent Isolation: The all-dielectric construction provides inherent isolation without additional components

This exceptional isolation performance results from the sensors' construction using only non-conductive materials:

• High-purity quartz optical fibers with excellent dielectric properties
• Dielectric coatings and protection materials
• No metallic components anywhere in the sensor or fiber cable

This high voltage isolation capability makes the sensors ideal for installation directly in high voltage environments without compromising electrical clearances or insulation integrity. The sensors can be placed directly on high-voltage conductors or components without requiring additional isolation measures or affecting the equipment's dielectric strength.

FJINNO monitoring systems are designed with flexible power supply options suitable for various installation environments:

• Standard Power Supply: AC/DC 220V (standard configuration)
• Alternative Options: Available configurations for:

The optical fibers use high-purity quartz cores with specialized protective coatings appropriate for the intended environment. For particularly demanding applications, additional protective conduits or coverings can be supplied to provide extra mechanical protection while maintaining the sensor's thermal response.

These robust design features ensure reliable operation for decades even in the challenging environments typical of electrical equipment installations, including high temperatures, oils, vibration, and chemical exposure.

One of the key advantages of FJINNO fiber optic temperature sensors is their exceptional long-term stability and maintenance-free operation:

• No Calibration Required: The sensors maintain their calibration throughout their entire service life without requiring periodic recalibration
• Self-Calibrating Technology: The fluorescence decay measurement principle is inherently stable and doesn't drift over time
• No Consumable Parts: The system contains no components that wear out or require replacement during normal operation
• Self-Diagnostic Functions: Continuous self-monitoring verifies system performance and alerts to any issues
• Reference Temperature Function: Systems can verify calibration against internal reference points

The stability of the measurement is based on fundamental physical properties of the rare earth phosphor materials used. Unlike conventional sensors that may drift due to aging, mechanical stress, or thermal cycling, the fluorescence decay time relationship to temperature remains constant over decades.

Routine maintenance is limited to periodic visual inspection of the monitoring unit and verification that fiber optic cables have not been physically damaged. The expected service life of the complete system typically exceeds 25-30 years, matching or exceeding the service life of the electrical equipment being monitored.
