Distribution Oil Transformer - alfanar

The short circuit impedance is the transformer’s impedance, usually between 4% and 6% for distribution transformers and higher than 7% for power transformers. The short circuit impedance is the percentage of the primary rated voltage that must be applied at the transformer primary winding when the secondary

MINIATURE CIRCUIT BREAKER

MCB (Miniature Circuit Breaker) is an electromechanical device which protects an electrical circuit from overcurrent and overload conditions. Unlike a fuse, an MCB can be reused after clearing the fault; offering im-proved operational safety and greater convenience without incurring large operating costs.
