TEV Sensor
Quickly detects Transient Earth Voltage (TEV) signals induced on the surface of ferromagnetic enclosures when partial discharge occurs in high-voltage power equipment. Features a strong magnetic attachment design and nanosecond-level pulse response, suitable for partial discharge monitoring across multiple high-voltage equipment types.
TEV SENSOR Features
- 01
High-sensitivity partial discharge detection technology
Quickly detects Transient Earth Voltage (TEV) signals induced on the surface of ferromagnetic enclosures when partial discharge occurs in high-voltage power equipment, effectively improving the ability to detect abnormal insulation conditions.
- 02
Strong magnetic attachment design
The TEV Sensor uses a high-strength magnetic base, allowing it to attach flexibly and firmly to the surface of high-voltage equipment's ferromagnetic enclosure. It is convenient for rapid on-site installation and long-term Online Partial Discharge Monitoring.
- 03
Nanosecond-level high-speed pulse response
Provides nanosecond-level response to partial discharge pulses, enabling real-time capture of high-frequency PD signals and improving PD Detection accuracy and fault identification capability.
Suitable for partial discharge monitoring in multiple high-voltage equipment types
- 01 Oil-immersed transformer
- 02 Switchgear
- 03 GIS (Gas Insulated Switchgear)
- 04 Cable joint or cable termination box (cable head)
- 05 Power distribution systems and transmission & distribution equipment
- 06 Widely used for power system predictive maintenance and equipment health diagnostics.
