- UAstute® HV 測量點裝置:
-
- 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.
- PD Alarms:
- 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.
