ASM Monitor
The worlds most successful on-line PD monitoring system
The ASM is the latest in a line of partial discharge monitors from IPEC Ltd. It incorporates all the features of IPEC’s previously successful monitors: the OSM v2.5 and OSM v3. Additionally it has a number of features that both enhance the quality of the data collected and make it more suitable for deployment in substations.
The ASM system can be configured with up to 128 PD sensor channels. If excessive discharge is detected on any sensor, the ASM raises an alarm on a central monitoring computer or alerts the customer by e-mail/SMS. This approach enables real-time, long-term assessment of plant condition to be carried out quickly and easily from any remote computer.
Suitable for all types of substation equipment, ASM provides a powerful tool to the asset manager, providing continuous on-line condition data at the touch of a button.

Partial Discharge Sensors
Sensors are distributed around the substation according to the monitoring requirements. Both active (with integral amplifiers) and passive transducers are compatible including the following:
Up to 128 sensors can be monitored by a single ASM.

- 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

Web Based Data Analysis
Partial discharge data collected from distributed monitors is stored on a central database and is hosted by IPEC. Customers have password protected access to this data directly over the Internet allowing them to browse the data and analyse plant condition from any PC.
Condition information presented like this can be used for targeting scheduled maintenance work before 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.

Alarms
Alarms including email, SMS and SCADA can be generated according to user specific parameters allowing the appropriate engineers and managers to be notified when the Criticality of a particular piece of plant exceeds its preset threshold.
Data can be viewed all together or arranged by substation or plant type.
Simple graphs can be displayed showing basic trends in partial discharge activity over time for each channel, PD signal wave shape and other information that is necessary for a full understanding of the PD, its likely source and Criticality.

Advanced Data Analysis
The Data Analysis page allows signals from any channel to be analysed. Data can be selected over any period and signals resolved in phase viewed. The analysis has the following features:
- Peak, Count, Load, 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 data in linear/polar representation
- Cumulative Count data
- Time of Day analysis
