SINGAPORE — The international solar energy company REC Solar has adopted online monitoring and diagnostics sensors from Hitachi ABB Power Grids for hydrogen and moisture monitoring in two of their transformers.

With the objective of ensuring high power supply reliability at its manufacturing facility in Singapore, REC Solar has adopted online monitoring and diagnostics sensors from Hitachi ABB for the two 75/95 MVA transformer units.

The digital sensors are expected to enable detecting the possibility of premature failure and the status of critical transformer health in real-time.  

The DGA sensors are part of the Hitachi ABB ecosystem for transformer digitalization. The ecosystem is open, scalable and manufacturer agnostic with a complete suite of products, software, services and solutions.
