UHF Portable PD Monitor
UHF Portable PD Monitor
Qualitrol offers DMS's UHF Portable PD Monitor. This is used to undertake periodic partial discharge surveys in substations to provide early warning of developing faults – enabling corrective action to be taken before complete breakdown occurs. Employing the same advanced UHF technology as the permanently installed PDMG-R system, the portable provides a PD monitoring solution for low-cost/low-value GIS where continuous, on-line PD monitoring would be uneconomical. The monitor, with integrated laptop, is easily transported in its heavy-duty, aluminium case. PD data from up to 3 UHF couplers is collected and stored, and the type of defect identified automatically through the in-built expert system analysis program. The collected data can also be retrieved remotely via connection to a LAN or modem. Additionally, the PDMG-P can be used to make the PD measurements now integral to high-voltage GIS commissioning tests.
PDMG-P benefits:
- Enables performance o f low-cost, periodic surveys
- Enhances systems reliability and reduces risks
- Detects faults before failure, damage or loss of supply
- Increases safety for personnel
- Determines condition of GIS insulation
- Extends residual life of ageing plant and defers capital costs
- Usable for HV GIS commissioning tests
- Easily portable
- Easy to use
