Power Switches testing

Testing in substations

Switches in disrepair can cause electrical arcs, singlephase operation or even fire. In addition, it is necessary to check the insulation periodically as this equipment is subjected to heating from energy created by high-voltages and high-currents; this inevitably affects the insulating material.

The most common tests in this type of switchgear are:

Contact Resistance

Terminals: power factor + insulation capacitance

Power Switch: Power Factor

Insulating fluids: power factor

Operating time
