The ageing of oil-immersed high-voltage power transformers is a concern to be taken into account by electricity network operators and managers. The prevention and rapid detection of breakdowns are essential measures to avoid incidents with sometimes serious, but always very costly and unnecessary consequences.
Our partner MTE offers monitoring devices for high voltage transformers, the Hydrocal 1001 and Hydrocal 1001+ devices.
All high-voltage power transformers are equipped with Buchholtz protection relays, the ultimate safety device of a transformer.
However, when this relay reacts, it is often too late…
Hydrocal is an instrument that continuously analyzes the gas emission level of the transformer’s oil cooling system.
It is indeed a measuring device that allows the monitoring of the aging of a transformer to manage more efficiently a high voltage substation. It is, therefore, a device for preventing failures on the network, such as fires and explosions …
