Breaker, relay, switchboard and transformer testing by Red Seal electricians and protection technicians, documented on field test sheets to manufacturer and NETA limits.
We perform full breaker servicing with primary and secondary current injection testing, verified trip times, mechanical exercising, lubrication, and contact resistance testing to ensure accurate protection and dependable operation.
We perform detailed dry-type transformer maintenance, including thermal inspections, ventilation cleaning, torque checks, winding resistance, and condition assessments to extend equipment life and reduce failure risk.
Engineering coordination studies & data collection
We provide complete arc-flash, short-circuit, and coordination study data collection and engineering analysis, ensuring accurate protective device settings, safety compliance, and optimized system performance.
We provide comprehensive cleaning of electrical switchgear, meticulously removing dust, dirt, and debris that can accumulate over time. Alongside cleaning, we conduct meticulous inspections to identify any signs of wear, loose connections, or potential issues that may require attention.
Breaker relay testing
Our specialized breaker relay testing services focus on assessing the accuracy, sensitivity, and coordination of these critical devices. Using advanced diagnostic tools and techniques, we thoroughly evaluate trip times, fault detection capabilities, and overall performance.
Transformer testing
Our comprehensive transformer testing services encompass a wide range of evaluations, including insulation resistance, winding resistance, and turns ratio. By meticulously assessing these key parameters, we can identify potential faults, degradation, or inefficiencies
