Analysis of Three Phase Transformer Parallel Operation and Circulating Current ijtsrd
Parallel operation of transformers is needed when the load is increased and it exceeds the capacity of the existing transformer, if multiple transformers are running in parallel and a fault occurs in one transformer, then the other parallel transformers still continue to serve the load. The reliability is increased with parallel operation than to have […]
Analysis of on Load Tap Changing Transformer for Substation ijtsrd
On load tap changing transformers play important roles in any modern power system since they allow voltages to be maintained at desired levels despite load changes. Traditionally, on load tap changer is a complex mechanical device, which has some deficiencies. On load tap changer of a transformer is presented, which can eliminate excessive conduction losses […]
