The detector is used to detect PD (partial discharge) in switchgears (3-40.5kV). It has been widely used in a power safety monitoring system for its high sensitivity and strong anti-interference ability.
Features:
· Detects and measures PD activity inside switchgears.
· Display intensity with blue orange and rend colors.
· Display pulse number in 2 seconds.
· Detect PD activity on the surface with ultrasonic sensor.
