DoblePRIME PD-Guard can be used with a variety of different sensors, including acoustic detection antennas for partial discharge, CTs for single or multiple conductors, UHF oil drain valve probes for use within the equipment, and insulating bushing end screen connectors.
Features of DoblePRIME PD-Guard PD Monitoring System
- Monitor partial discharge and configure monitor via computer, tablet, or web-enabled device
- Works with a variety of sensors including antenna for airborne PD, CTs for individual or bundled conductors, UHF drain valve probes for in-tank applications and bushing tap connectors
- Built-in Expert System learns PD behavior and indicates changes in frequency and/or severity of measured PD levels
- Alarm relays for external notification
- Broadband RF signal detection including peak, average, and quasi-peak
Benefits of DoblePRIME PD-Guard PD Monitoring System
- Monitor PD in critical and high-risk assets
- Save costly equipment by quickly reacting to rapid insulation deterioration warnings
- Identify problem areas, diagnose the severity of the situation, and plan action and intervention
- Plan for further testing, maintenance, and replacements in a proactive, risk management approach
- Use as a standalone product, networked to an existing SCADA system, or as part of a DoblePRIME Condition Monitoring Platform
