Designed for live display devices in 10kV-40.5kV power systems, this capacitor provides real-time indication of the operating status of:
- High-voltage conductors
- Circuit breakers (SF6 and vacuum types)
- Lightning arresters
- Instrument transformers
Ensures operator safety with typical parameters including capacitance ranges from 10pF-230pF (e.g., 90pF at 24kV), withstand voltage of 68kV (power frequency) and 125kV (lightning impulse).
PD not more than 5pC at 1.1 times rated voltage without special instructions. Comply with standard DL/T538-2006 (High Voltage Presence Indication Device).
Dimensions can be customized according to customer requirements.
Special attention required to prevent product damage, moisture exposure, and contamination.
Complies with standard JBT10305-2001 (Technical conditions for post insulator of organic material in the 3.6kV-40.5kV high voltage equipment).
For installations below 100 meters or in high altitude areas, please specify in order notes.
