APT-308 overhead type grounding and short circuit fault indicator (four-remote type) APT-308 is a four-remote grounding and short-circuit fault indicator for overhead lines of 35KV and below.

APT-308 through

Real-time measurement of cable current and according to the current waveform changes to determine the power line short-circuit fault and grounding fault, and the fault state, real-time current (

Fault current), battery voltage, cable temperature, ground electric field and other information uploaded to the remote server, for the rapid diagnosis, positioning the various types of overhead lines

Failure to provide reliable data.

APT-308 can be flexibly configured using a hand-held PDA (APT-307) or a communication terminal (APT-309) during its use,



To meet the monitoring needs of different aerial environments.
