PD Doctor – Partial discharge diagnostics

PD Doctor analyzer

Measurement module that forms the heart of the PD Doctor system. The module measures high-frequency signals, evaluates partial discharge activity from them, and delivers measured and processed values to the supervisory system.

PD Doctor Analyzer

The analyzer, as the core of the PD Doctor system, offers precise and reliable diagnostics and online
monitoring of insulation condition in medium and high voltage lines and equipment in transformer and distribution stations.

Key features:

24/7 continuous monitoring of partial discharge activity
Multi-channel unified architecture support
High-speed connectivity via OPC UA (Open Platform Communications Unified Architecture)
Compatible with IEC 62541 data exchange standard independent of the manufacturer of system application provider
Includes IEC 61850 compatible overlay for use in energy sector
Provides wide data range, from raw samples to statistics
Communicates with PD Doctor Application for measuring, analyzing and monitoring partial discharges
