Repairs, maintenance and testing procedures
REV’s transformer maintenance and repair services are backed by a roster of highly specialized testing procedures, each conducted to NETA standards and meeting Acceptance Testing Standards and Maintenance Testing Standards. Field tests include Power Factor (Doble) testing, Sweep Frequency Response (SFRA), insulating oil and gas analysis and Turns Ratio/Winding Resistance/Capacitance and DF testing. Upon reviewing the resulting data, REV’s field service representatives are often able to perform repairs immediately on site severely limiting potential downtime.
