Product category : Transformers
Vijai electricals completely self protected transformers [csp] offer a complete and safe solution against lightening, switch surges and severe secondary overloads.
Benefits
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.
More reliable service: 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 management may be necessary.
Lower system cost : considering the operating costs of energy supply and replacement cost 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 transformer and only one high voltage electrical connection to the distribution line.
