Apply the 80% Rule: The National Electrical Code (NEC) states that transformers should only use up to 80% of their maximum capacity to ensure safe operation and ensure the system is not overloaded. Exceeding this threshold can overstress the transformer causing unreliability or a shortened life.
The power transformer can be divided into three types: small power transformer, medium power transformer, and large power transformer.
Insulated gloves prevent electrical shock. Usage of safety glasses protects the eyes against sparks, debris, and oil splashes. Flame-resistant clothing reduces the risk of burns in case of an electrical arc. Safety boots with electrical insulation prevent from any type of grounding hazards.
In the high-voltage test of power transformers, the dielectric loss factor test is one of the basic insulation preventive test items. The main purpose of the test is to determine the insulation performance of the transformer according to the size of the dielectric loss factor.
