DISTRIBUTION TRANSFORMER WITH AMORPHOUS-CRGO CORE: AN EFFORT TO REDUCE THE COST OF AMORPHOUS CORE DISTRIBUTION TRANSFORMER

Posted on by appliedelectricalengineering

In distribution transformer design, main stress is to reduce core losses. To reduce core losses in distribution transformer cold-rolled grain oriented (CRGO) steel is preferred by manufacturers. Amorphous material has very less core losses compared to CRGO steel, therefore it is being seen as a good substitute of CRGO steel. Now-a-days some manufacturers are using amorphous material in miniature and medium size transformers in place of CRGO steel. The cost of amorphous core transformer is higher than the cost of CRGO core transformer. Here an effort is being made to reduce the cost of amorphous core distribution transformer by using a ‘CRGO-Amorphous’ core in place of amorphous core. A comparison is being presented here among ‘CRGO core distribution transformer (CCDT)’, ‘amorphous core distribution transformer (AMDT)’ and ‘Amorphous-CRGO core distribution transformer (AMCCDT)’, in terms of cost and efficiency.
