Product Overview

The Iris Power PDTracII system provides automated, continuous partial
discharge (PD) monitoring with configurable alarms that initiate on high partial
discharge levels.
• PDTracII works with permanently installed epoxy mica capacitive sensors
on motors, generators, dry type transformers and switchgear over 3.3 kV
• The PDTracII continuously collects partial discharge data to produce
phase resolved plots and summary numbers (Qm and NQN) for trending
and comparison.
• The PDTracII uses pulse shape analysis to reliably distinguish partial
discharges from electrical interference (noise) in order to prevent false
alarms when the monitored equipment is connected to the power system
by >30 m of power cable.
• The test frequency range is from 40 MHz to 350MHz while working with
80 pF Epoxy Mica Capacitors (EMCs) and 2 MHz to 350 MHz with 1 - 2 nF
capacitive couplers.
