SCM-PDS3W Wireless PD Sensor

SCM-PDS3W partial discharge sensor

SCM-PDS3W AE TEV UHF Wireless PD Sensor

The SCM-PDS3W PD sensor integrates ultrasonic, TEV (Transient Earth Voltage), and UHF (Ultra High Frequency) technologies to detect partial discharges in middle-high voltage equipment. SCM-PDS3W can monitoring of transformers, high-voltage switchgear, GIS (Gas-Insulated Switchgear), and cable joints. SCM-PDS3W is highly portable, offers fast measurement speeds, and boasts strong anti-interference capabilities, making it suitable for various field applications.
