FAQ：
Q1: What voltage range can this fault indicator be used for?
A: The JEC-HW overhead line fault indicator is designed for 5~38kV overhead distribution networks. Customized solutions are available for 44kV, 69kV and 110kV systems.
Q2: What types of faults can it detect?
A: It can detect short-circuit faults and earth faults. Permanent faults, transient faults and low battery warnings can be separately indicated by different LED signals.
Q3: Can the fault information be transmitted remotely?
A: Yes. The DCU can transmit fault information and current values to the SCADA system through 2.5G/3G/4G communication networks.
Q4: How is the fault indicator installed?
A: The indicator can be installed on live overhead lines with an adapter and hot stick, allowing installation without power interruption.
Q5: What is the service life of the battery?
A: The replaceable lithium battery has a service life of up to 10 years under normal operating conditions.
