Partial Discharge (PD) monitoring is a highly reliable method that can be used anytime to diagnose the insulation condition of an electrical asset. It provides engineers with practical information which allows them to detect even the tiniest weak points in a system.

Power Technologies offers PDS’s world-class monitoring and diagnostics systems that utilise technology and innovation, such as the Internet of Things and Artificial Intelligence. These elements enable its sensing technology to monitor power systems and collect huge chunks of data for more efficient operations.



PDSurvival, an intelligent PD Monitoring System

PDSurvival is the latest PD monitoring system designed for distribution equipment in medium voltage applications. The system is built and innovated upon the success of its predecessors, making it capable of achieving simpler and better monitoring results.
Key features of the PDSurvival also includes:

  • Ultra-wide band frequency for incorporating with multiple sensor types
  • Dual-band monitoring for monitoring and analysing PD signal in two bandwidths
  • Auto risk assessment for interpreting the criticality based on the PD detected
  • Pattern recognition for recognising and categorising different PRPD patterns
  • Machine learning for self-improvement in the accuracy of interpretation

PDProbe, the all-in-one handheld solution for PD Measurement

Designed to simplify the inspection process in substations, PDProbe’s fast-scanning capability and multiple detection methods allow users to quickly survey equipment condition. It’s also equipped with dual detection channel and powerful auto-analysis function which is vital in determining PD type.
Apart from efficient PD Detection and an enhanced analysis function, PDProbe boasts its:

  • Wide-range of sensors that allow accurate results
  • Dual channel for comparison of different detection methods
  • Capability to reduce unnecessary sensor changes
  • Multiple display modes to see PD detail
  • Auto-recognition of PD type for better analysis process
  • Signal recording of both channels
  • NFC tag function which improves on-site test procedures
  • Capacity to help eliminate unscheduled downtime and minimise scheduled downtime

MOCOM, an integrated system for Motor Condition Monitoring

Motor Condition Monitoring System (MOCOM) provides various information on electrical and physical properties, allowing professionals to discover potential failures from any type of problems, including wearing or bearing.
Environmental dust and lack of lubrication are common issues that could lead to motor faults. With the aid of MOCOM, the situation could be effectively prevented. MOCOM products include:

  • MOCOM-M for monitoring electrical aspects
  • MOCOM-VT for monitoring physical aspects
  • MOCOM-DC for data collection

EnviAir, a substation remote monitoring system

PDS’s EnviAir is specially designed for substation and condition monitoring, which includes three main indications: temperature, humidity and ozone. Apart from being easily implemented on switchgears, EnviAir enables the constant monitoring of both internal and external temperature and humidity, effectively preventing false alarms caused by environmental factors.
Key features of the EnviAir also includes:

  • Up to 1 minute of recording interval (default)
  • Wireless communication with its compact size for easy installation
  • Battery power for up to 18 months
  • Trend graph for easy tracing and report making
  • Adjustable alert notifications for internal overheat, excessive temperatures, excessive ozone concentration, low battery and system fault
