Switchyard Testing
Switchyards are critical hubs that regulate, route, and protect the flow of electricity across transmission and distribution networks. At SLPL, our Switchyard Testing Services ensure these infrastructures operate reliably under all load and fault conditions—minimizing downtime and maximizing system stability.
What is Switchyard Testing?
Switchyard testing is a suite of diagnostic and performance verification services carried out across all primary and secondary equipment in a substation or switchyard. These tests are essential for:
Commissioning new switchyards
Routine preventive maintenance
Condition assessment of aging infrastructure
