Tristar offers Preventative Maintenance plans to identify and correct potential problems before a crisis occurs for all legacy and new power distribution units.
During preventive maintenance, our field service engineers perform a complete check on the power transformer and the circuit breakers with a fluke infrared camera (optional service) or an infrared gun to identify hot spots or overheating, caused by a load imbalance or loose connections. Additionally, our field service engineers also check the ground currents, neutral currents, and harmonic voltage and current to ensure all these currents are within the limits set by the manufacturers.
Tristar field service engineers will also compare readings displayed on the display monitor of PDU with their own calibrated meters to ensure proper calibration of the display monitor.
