Circuit breaker testing

Breakers in poor condition can cause arcing, single phase operation, or even fire. In addition, it is also necessary to periodically check the insulation since the high voltage and current passing through this equipment causes heating, which inevitably affects its insulating material.

For this reason, at 4fores , we offer switchgear testing to evaluate:

• Contact resistance
• Terminal: power factor + insulation capacitance
• Circuit breaker: Power factor
• Insulating fluids: Power factor
• Switching time
