Inspection of Three Types of Relay Protection Devices
Protective relay testing is usually divided into three categories: acceptance testing, commissioning, and maintenance testing. Acceptance or evaluation testing determines whether a relay is appropriate for use on a specific protection application within a power system. Distance Relays: Measure impedance to detect faults in transmission lines, aiding in fault location and isolation.

High-voltage busbar trunking inspection
Daily Inspection: Visually inspect the busbars for any abnormalities such as cracks, rust, deformation, or discoloration. Dielectric testing ensures the insulation of busbars can withstand the operating voltage and environmental conditions without breaking down. The purpose of this method is to verify the functionalities of a Metal Enclosed Busb ar. The test shall be carried out according to IEC 60068-2-2 Test Bb, at a temperature of 70 °C, with natural air circulation, for a duration of 168 h (7 days) and with a recovery of 96 h (4 days). Our team utilises fully calibrated equipment for inspecting, servicing, and conducting electrical tests and diagnostics to address busbar performance issues.
