Partial Discharge Management System
|In the inlet transformer where insulators including insulating oil, insulating paper, and press board are used, poor manufacturing of insulating materials or deterioration of age may result in initial partial discharge due to weakening of insulation strength. Depending on the time of use, such partial discharge will further weaken the insulation resistance, leading to unforeseen major accidents.
The UHF PD Measurement Sensor (ISAAC-PDS-DV500) is a transformer drain valve-in-place sensor connected to a system that pre-detects insulation deterioration of the transformer.
The above equipment detects signals in the UHF band and improves measurement sensitivity and is good for external noise interference.f
|• Real-time diagnosis of power facilities by real-time partial discharge measurements.
• Reduce installation costs by allowing it to be installed while driving.
• Simple maintenance by installing directly on to transformer drain valves.
• Improved sensitivity and reduced external noise through UHF band measurement method.
