ZXPD-100K switchgear partial discharge detector
Product usage :
ZXPD-100K switchgear partial discharge detector is mainly used for high-voltage switchgear partial discharge inspection and positioning. It includes two detection modes: ground wave (TEV) and ultrasonic. The ground wave detects the internal discharge activity of the switchgear and has single detection and continuous detection. Mode, the ultrasonic can also detect and locate the internal discharge of the high-voltage switchgear.
Product Description :
1. Application: non-intrusion method for routing inspection and position of partial discharge defects
2. Standard: ultrasonic (UA) sensor,transient earth voltage sensor (TEV)
3. Options: Special sensor for Power Transformer,GIS,HV cable. Can be customized.
4. Detection principle:ultrasonic method (UE), TEV method, UHF method
5. Built-in ultrasonic sensor, TEV & UE sensor, Transformer/GIS/Cable use sensor for options
6. Continuous detection of UHF, TEV, Ultrasonic signals to determine if there is a partial discharge.
7. Signal change trend display in real time, for intuitive judgment on its development
8. Real time data storage capacity up to 1000 sets
9. High contrast 3.5 inch TFT color screen

OPERATION CAUTIONS:
When using TEV type products, it is necessary to abide by the following rules:
1. The strong electromagnetic interference in the frequency range from the DC generated by mobile phones, RF transmitters, video displays and unshielded electronic equipment to 1 GHZ can influence the reading, so the product should be placed in a free space at least 1m away from any conductor surface in order to measure the value of the local electromagnetic field.
2. Please be careful when using the instrument in a narrow space, because the reading accuracy may be influenced when the instrument is near to any other grounding plane. Therefore, it is necessary to use the instrument at the place at least 30cm (vertical distance) away from any metal object.
