Auxiliary equipment
● Fault Indicator: The DJD-1 short-circuit grounding fault indicator uses logic circuits for over-current alerts and manual reset, with sensors on cables and a display unit for quick fault detection.
● Condensation Controller: This device monitors temperature/humidity in real-time, activating heaters at 85%RH to prevent condensation (rated power: 75-100W).
● FTU & Communication: The DAT-1L automation terminal enables SCADA integration with 48 remote signaling channels, self-diagnosis, and multi-protocol support (IEC101, MODBUS, etc.).
● Current Limiting Fuse: Designed for 24kV/50Hz systems (292mm length), it protects indoor switchgear from overcurrent faults.
