What is Partial Discharge?

PD is an electrical discharge that occurs at a specific point on an insulator. When PD begins and repeats, it can damage the insulator and may lead to failure of the whole high voltage power equipment.

Motor Coil Resistance Test

The resistance of motor coils affects energy loss, which turns into heat and causes the motor windings to rise in temperature. Knowing the actual resistance value under operating condition is important to design energy-efficient electrical equipment.

Magnetic Characteristics Test

Magnetic materials for transformer and motor play the most important part in converting energy. In order to make energy saving products, it must be designed to minimize electrical loss.
