Doble PRIME PD-GUARD

The doblePRIME PD-Guard continuously monitors partial discharge (PD) in transformers, rotating machines, cables and switchgear including GIS and metal clad. It analyzes both PD and EMI emissions in HF, VHF and UHF ranges, providing actionable alerts when insulation deterioration is detected. The doblePRIME PD-Guard provides local alarms and will communicate data and notifications across standard interface channels and through to networked supervisory systems. The doblePRIME PD-Guard includes multiple analysis capabilities, including IEC 60270 consistent measurements, Qiec, and an enhanced IEC measurement more suitable for field applications, Qhf. The built in Peak-to-Average-Power Ratio (PAPR) tool trends PD/EMI severity, and alerts when deeper diagnostics of Phase Resolved, level resolved or time resolved signal analysis is recommended. The doblePRIME PD-Guard 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 sensors. Designed to fit your monitoring program, the doblePRIME PD-Guard can operate as a standalone device or as part of a doblePRIME Condition Monitoring Platform.
