Completely Self-Protected Transformers (CSP) offer a complete and safe solution against lightning, switch surges and severe overloads.
Higher Transformers 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 transformers and secondary current flow, allowing the transformers 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.
More Reliable Services : CSP Transformers efficiently and effectively disconnect the load from the transformer under overload conditions. Moreover CSP components help in identifying locations where improvements in load managements may be necessary.
Lower System Cost : Considering the operating costs of energy supply and replacement costs of the transformers that have failed prematurely due to overload, CSP transformers would no doubt fair better than conventional ones.
Easier and Simpler Installation: Involves only one piece of electrical equipment, The transformers and only one high voltage electrical connection to the distribution line.
