Why Magnetic Core Balance test is performed only on Star side of Transformer and not on Delta Side of Transformer (Vector Group Dyn11)?
1 3096A simple Question from all.... If Voltage drops then its rated value what will be effect on a Residential load? similarly if voltage rises from its rated value then what will be effects on a load? i know if voltage drops the equipment or device draws more current then its rated what are other reasons ? thanks in advance for ur time.......
