Award winning advanced asset monitoring and PD alarm system
For 24/7 monitoring of Partial Discharge (PD) activity in substation switchgear and cables
Comprehensive PD Monitoring:
Provides valuable information on the actual condition of assets. The Award Winning Astute® HV enables progressive management of substations through its ability to precisely measure and analyse the actual condition of assets simultaneously.
Enhances the effectiveness of asset management, by improving reliability and efficiency with reduced costs
Reduces unplanned switchgear outages
Increases site safety
Next Generation Technology: The Astute® HV is the product of EA Technology’s unique experience as a pioneer in the measurement and interpretation of PD activity for nearly 40 years.
Multiple Sensor Systems: The Astute® HV is part of a new generation of asset management systems, combining the functions of multiple PD instruments in a single package.
Benefits and Features:
Cost of installation payback within two years
Astute® HV unique external noise cancellation allows it to identify PD in high noise environments
PD is located with unrivalled precision, eliminating costly investigations
Innovative non-intrusive measurement technology allows flexible system installation and movement with switchgear outage and minimal cabling
Continuous online condition monitoring provides early detection of asset deterioration, enabling informed preventative measures
Internal PD, surface PD and PD in cables are all measured and analysed thereby pre-empting failures
Monitoring of environmental conditions correlates changes in PD with humidity and temperature
Configurable alarms and notifications allow instant response to deteriorating conditions
Intuitive web-based management and data analysis system is simple and easy to use
The option of intelligent cloud-based solution capable of remotely managing multiple systems
Capacity for up to 300 individual PD measurement points so that even the largest of systems can be covered
Product options include both fixed and portable systems to suit large or small site requirements
System Capabilities: The Astute® HV continuously monitors hundreds of points simultaneously, measuring the location, magnitude and severity of PD activity.
PD Detection: Continuously checks for the presence of PD activity on the surface of insulation, internal to components and in cables while recording over time.
Alarm systems with intelligent configuration capabilities, allowing thresholds to be set individually on each channel, for different measurement types
Optional notifications via SCADA, email and SMS.
PD Measurement: Collates PD activity from up to 300 concurrent measurement points.
PD Trending: Monitors changes in PD activity from up to 300 concurrent measurement points over time, together with correlation to environmental condition (temperature and humidity).
PD Analysis: Evaluates and reports on PD activity continuously, with data accessible on the device, on the desktop or via the cloud.
PD Location: Uses time-of-flight measurement to a resolution of 1ns (nanosecond), locating the source of PD activity to within 30cms. Amplitude is not a sufficient indicator of PD so time-of-flight is used to gain an accurate location.
