Pioneering the future of power testing and monitoring
OLTC DGA monitoring
The DGA units incipient stage, before they develop into major faults and result in the outage of the transformer. The conventional BUCHHOLZ RELAY is universally used in transformers to protect against severe damages. However, its limitation is that enough gas must be generated first to saturate the oil fully and then to come out or there should be a gas surge to operate this relay. Moreover, Buchholz Relay is never meant to be a diagnostic device for preventive maintenance of transformers.
The Transformer FGA is fault gas monitoring unit which is designed for smaller transformers to prevent serious faults in the earlier stage, plan outage and replacement and evaluate asset condition. It is capable of monitoring hydrogen gas generation, methane generation, moisture and complete fault gas pressure.
