The EA Technology UltraTEV Plus+ is a state-of-the-art, handheld instrument designed for the detection and measurement of Partial Discharge (PD) activity in high-voltage (HV) and medium-voltage (MV) electrical assets. This portable device is a critical tool for predictive maintenance, enabling engineers and technicians to identify potential insulation defects in electrical equipment before they lead to costly and dangerous failures.
Dual-Sensor Capability: The seamless integration of TEV and ultrasonic sensors in a single unit provides a comprehensive diagnostic tool.
Clear Data Display: A color Liquid Crystal Display (LCD) screen provides clear numerical and graphical representations of PD activity, allowing for immediate analysis and trending over time.
Audible Feedback: An audible output through headphones allows operators to “hear” the ultrasonic PD activity, providing an intuitive way to locate and assess the severity of the discharge.
Data Logging and Trending: The device can store and trend data, enabling maintenance professionals to monitor the condition of assets over time and make informed decisions about maintenance schedules.
Versatile Accessories: A range of optional accessories, such as contact probes and parabolic dishes (UltraDish), enhances the instrument’s capabilities for inspecting sealed units and assets at a distance.
The primary application of the UltraTEV Plus+ is the condition-based maintenance of electrical infrastructure. It is widely used in various industries that rely on high-voltage electrical systems, including:
Power Generation and Distribution: Utility companies use the device to assess the health of their substation equipment, ensuring network reliability and preventing outages.
Industrial Plants: Large manufacturing facilities with their own HV/MV infrastructure utilize the UltraTEV Plus+ to minimize the risk of production downtime due to electrical failures.
Renewable Energy: The instrument is used to inspect the electrical components of wind farms and solar installations.
Transportation: Rail networks and other transportation systems with significant electrical infrastructure benefit from the proactive maintenance capabilities of the device.
