in-situ control: the "remote/cut/in place" switch is set to "in place" and the "a-phase", "B-phase", "C-phase", "AB-phase", "BC-phase", "AC-phase" knobs on the panel are active.
The fault resistance adjusting knobs of the phase A, the phase B, the phase C, the phase AB, the phase BC and the phase AC are adjusted to different resistance values, so that different fault scenes (such as single-phase grounding, two-phase short-circuit faults, two-phase short-circuit grounding faults, three-phase short-circuit faults and three-phase short-circuit grounding faults) can be realized.
Remote control: setting the change-over switch to be 'far', setting the transition resistance on the panel to be invalid in operation, and setting related parameters to simulate different fault scenes through a dynamic simulation platform TCP.
Excision: when the "remote/cut/on-site" switch is set to "cut", either the "on-site" or "remote" control is used, all operations fail, the fault connection is broken, and the indicator light is turned off.
IGIR-B code pair: the external time setting is carried out by the serial port RS485 and RS 485.
