Partial Discharge Testing

Partial Discharge Testing

Partial Discharge Testing can allow you determine to your planned preventative maintenance, repair or the replacement of your switchboards and other equipment, resulting in a preventative method rather than having to replace equipment such as switchboards as an emergency which will incur uneconomical cost and downtime.

Partial discharge occurs within layers of insulation of High Voltage equipment, it is a low level discharge that occurs within cables, joints, terminations, switchgear. Each discharge while at low level is crossing the air space gap present within layers of insulation or production faults within the material.
Repeated discharge eventually breaks down the insulation to create a failure in the insulation, this is usually catastrophic and result in a replacement of usually a highly expensive piece of equipment.
