Product only available in USA and Canada.
 
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.
 
Key Benefits
 
Portable but powerful
ASM-Portable has the full power of our ASM system, in a portable design
 
Continuous Monitoring
24/7 PD Monitoring, ensures PD is quickly detected before failures occur
 
Automated Analysis
ASM will automatically detect and identify PD, without the need for manual analysis
 
Web Based Data Analysis
Partial discharge data is automatically collected from the ASM-P and is stored on a central database and is hosted by IPEC. Customers have direct password-protected access to this data via the Internet, allowing them to browse the data and analyze plant condition from any PC.
 
Condition information presented like this can be used for targeting scheduled maintenance work before the failure happens, improving network reliability and prioritising asset replacement.
 
Based on the magnitude of activity levels recorded and the trend in that activity, a ‘League Table’ is automatically generated once every 24 hours. This table gives a clear and quantitative representation of the condition of monitored high voltage assets at any given moment.
 
The PD Data Analysis page allows signals from any channel to be analyzed. Data can be selected over any period and signals resolved in phase viewed. The analysis has the following features:
 
PD Peak, PD Count, Load, Asset Criticality and Analogues plotted against time
Any time period selectable
Up to 8 channels selectable at one time
Multiple thresholds for count between 5mV and 100mV
Data Averaging and Noise Reduction functions
Rectified/Bi-polar graphs
Phase resolved PD data in linear/polar representation
Cumulative Count data
Time of Day analysis
 
Partial Discharge Sensors for ASM-Portable
Sensors are distributed around the substation according to the monitoring requirements. Both active (with integral amplifiers) and passive transducers are compatible including the following:
 
High Frequency CTs – for cable PD detections
Capacitively Coupled – for TEV (Switchgear) PD detection
Airborne Acoustic – for Surface tracking or corona
Temperature and Humidity – environment measurements
Up to 32 sensors can be monitored by a single ASM-P.
