PD-RDM300

The PD-RDM300A is the newest device in the PowerPD line of test equipment, which provides continuous monitoring of your metal clad switchgear (MCSG)including Standoff Insulators and cable terminations (joint). This device detects RF (Antenna) current (HFCT) when partial discharge occurs on the insulation system. It determines the PD fault frequencies by scanning the 4 -100 MHz range. Data is collected in bursts (Envelop) by the count method. This trends the measurement of switchgear and terminations (joint) deterioration and will give early warning to prevent a catastrophic failure. (See images below) Breakdown occurs when your MCSG has defective insulation due to moisture, dirt, and failure of heaters and a lack of a pro-active preventive maintenance program.
