Partial Discharge Testing

Powertest Asia Private Limited is one of leading company in India for providing a wide range of services for partial discharge testing. Partial discharge testing is done for checking the electrical breakdown or insulation capacity in devices due to high pressure of voltage. Partial discharge in equipments affects the insulation and indicates breakdowns. These discharges can occur in insulators that contain gaseous inclusions, cavities, or voids.

We use different types of Partial Discharge Measurement devices for performing this test. PDA Couplers and TVA probes are used for detecting partial discharge in generators and other equipments. Partial discharge testing carried out by us accurately specifies the poor condition of insulation and thus reducing the failure of the equipments. This test can be conducted in normal operating conditions.

Partial discharge testing does not affect the equipment under test and most of the times the occurrence of partial discharge can be identified within the test object, thus allowing the solving of the problem. The Partial Discharge Measurement analysis are used to predict the electrical equipment which needs to be repaired. This test is widely applicable for testing insulations of cables, rotating machines like turbines, generators, transformers, gas insulated switchgears etc.
