Completely Self-Protected Transformers(CRGO Silicon Steel / Amorphous Metal)

Higher Transformer Availability : Available for a longer duration than conventional transformers. Internal breaker (Type CLR) is tripped by a standard Bi-Metallic thermal trip element, which integrates oil temperature and secondary current flow, allowing the transformer to continue to operate even under overload conditions, until the oil temperature makes coil damage imminent. Improvised CQR Type breakers can also be provided which are furnished with instantaneous magnetic trip element in addition to the Bi-Metallic thermal trip element.
