Opsens’ transformer hot spot monitoring solution is the most reliable fiber optic temperature system available today. Based on the field proven GaAs based SCBG measuring technique used in transformers since the 1990’s, Opsens direct, accurate & real-time transformer hot spot measurement addresses the critical issues encountered by transformer manufacturers and electric utilities managers: robust sensor, ease of installation, long-term reliability and easy system integration in the Utility’s infrastructure.
Opsens innovates in providing a fully configurable hot spot temperature monitoring solution.
At Opsens we realize that electric Utilities and Transformer Manufacturers alike have their specific preferences when it comes to fiber optic probe installation.
Benefits & Added Value
The PowerSens II is now fitted with an internal reference that allows regular self verification and correction of system calibration. The internal reference guarantees long term accuracy in the most adverse conditions encountered in a transformer environment such as temperature variations, component aging, mechanical chocks and transformer vibrations.
In combination with the OTG-T+ or OTG-T fiber optic sensors, the PowerSens II provides the Best Total System Accuracy in the winding hot spot monitoring industry at ± 0.8 °C (sensor & signal conditioner).
Opsens has implemented a fully traceable new calibration method that assures long term traceability of both the PowerSens II and the OTG-T family of fiber optic sensors. Combined with the internal reference of the PowerSens II, this new calibration method provides unparalleled reliability to Opsens transformer temperature monitoring devices.
System accuracy and reliability are then secured over lifetime.
Opsens now provides a six-year warranty on all PowerSens II and PicoP signal conditioners supplied to the power transformer industry.
Opsens offers robust, easy-to-install, easy to use fiber optic sensors that were developed specifically for winding temperature monitoring and that can be configured depending on user’s specific needs.
Benefits from Opsens fiber optic temperature sensors are many: our small, encapsulated probe and flexible fiber optic cable have great resistance to mishandling and winding compression, eliminating the need to ‘double the count’ of sensors.
Our easy to install temperature sensors fitted with a Nomex™ spacer insert disk allow for fast, hassle-free installation in the windings with optimal probe position for the best hot-spot reading and ideal sensor protection, crucial during winding compression.
Moreover, our innovative 2-step fiber optic sensor winding installation process prevents accidental damage occurring during winding construction and vapor phase: by installing short fiber optic sensors in the windings’ hot spots and doing final connection using all-dielectric material, cable breakage is nearly inexistent.
Customers using Opsens’ unique installation technique obtain maximum sensor yield while saving valuable time and money.
Whether you use the Classic fiber optic installation solution or the enhanced Zero Fault System, you will be able to rely on one of the best temperature monitoring system.
