Partial Discharge Monitors

Acquire, process and display PD data remotely with our permanently installed monitors

On-line Partial Discharge monitors vary in complexity and design, depending on the environment in which they will be permanently installed.

Large systems are installed in MV substations, monitoring every cable and every switchgear. More industrialised devices are used in distributed applications, such as small substations and EHV assets.

Partial Discharge Monitoring Systems

ASM Systems – Permanent PD Monitor

The ASM is a permanent PD monitor for cables, switchgear and other high voltage assets. The ASM can be configured for any number of PD sensor channels. If excessive discharge is detected, the ASM raises an alarm that can be configured either locally or by email. This enables the long-term assessment of plant conditions to be carried out quickly and easily, from any remote computer. Suitable for all types of substation equipment, the ASM proves a powerful tool to an asset manager, providing continuous on-line condition data at the touch of a button.

  • The ASM uses PD sensors that couple to the HV network
  • The monitor is enclosed in a 19″ cabinet allowing for customisable options
  • The ASM automatically downloads to a central database

ASM-Portable – Portable PD Monitor

The ASM-Portable is a Portable Partial Discharge (PD) Monitor for cables, switchgear, and other high-voltage assets. The unit is part of the IPEC’s wider range of on-line PD monitoring systems. The ASM-P can be configured with up to 32 PD sensor channels. If excessive discharge is detected, the ASM-P raises an alarm that can be configured either locally or by email. This enables the long-term assessment of plant conditions to be carried out quickly and easily, from any remote computer.

  • PD Peak, PD Count, Load, Asset Criticality and Analogues plotted against time
  • Any time period selectable
  • Up to 8 channels selectable at one time

PD Alarm

The PD Alarm is an asset mounted device for indicating the presence of partial discharge in high voltage switchgear, ring main units (RMUs) and dry type transformers. Designed for use in small substations, the instrument can activate local and remote alarms in addition to local indication.

  • Ultrasonic and TEV level displayed in dB
  • Current ‘live’ alarms and historical alarms
  • Measurement of electrical transients generated by internal PD

DeCIFer – PD Noise Cancelling

There are several factors that affect the quality of On-line partial discharge detection including sensitivity of sensors, rate and quality of data acquisition and most importantly, quality of PD noise filtering. IPEC’s DeCIFer algorithm is a market leading tool for removing noise and identifying PD.

  • Market leading tool for removing noise and identifying PD
  • Use our years of experience to automate PD detection
  • Ensure PD is found and false positives a kept to a minimum
