Transformer Protection and Control
As transformers are expensive yet essential elements in power systems, protection schemes should be curated to detect and solve any unprecedented conditions quickly. In our advanced transformer protection and control devices, Schneider Electric India implements the best techniques such as multiple winding differentials, REF and thermal algorithms, and collect service data to aid the scheduling of preventive maintenance. Supply causes, lightening over voltages, switching over voltages, are some of the many factors that pose threat to transformers. Further, the result of any overload is the increased temperature of the transformer's oil and windings, which severely impacts its longevity. In order to safeguard of a transformer against overloads, several industrial sectors deploy a special kind of electric relay called thermal overload relay. This kind of protection mirrors the temperature of the transformer's convolutions, and the resemblance is based on the measure of the current and the transformer's constant thermal time. Some relays can eliminate the effect of harmonics of the current resulting from non-linear loads such as rectifiers, computers, variable speed drives, etc. This kind of relay can also evaluate the outstanding time before the release of the tripping order and the time-lapse before re-energizing the transformer.
