I Δ s mode: Grounding fault location in ungrounded systems, receiving positioning current signals collected by measuring pliers;

I Δ n mode: residual current measurement of the grounding system, displaying the residual current value of the branch.

Key features: 3-line 16 character backlit LCD display screen, ALARM LED alarm light (lights up when the threshold is exceeded); Support HOLD data retention, RESET reset, and INFO device information query; Charging through MicroUSB interface.

The PGH series current injector (positioning signal source) is responsible for generating stable positioning current and driving the fault location of ungrounded systems. Different models have clear adaptation scenarios: | Model | Adaptation Scenario | Power Supply Voltage | Maximum Positioning Current (optional) | Core Features|

Operation and usage characteristics

Core operating procedures

Mode switching: Use the EDS195P mode selection key to switch between "Fault location (I Δ s)" or "Residual current measurement (I Δ n)";

Clamp type selection: Match the corresponding type (such as P20=PSA3020/3320) with the selection key based on the measurement clamp model used;

Data processing: Press the HOLD button to save the current measurement value, and press the RESET button to reset; The MENU key enters the parameter adjustment interface (such as response value, harmonic setting);

Alarm indication: When the measured value exceeds the set threshold, the ALARM LED lights up to indicate a fault.

Typical application scenarios

Scenario 1: Independent online fault location (without installed equipment): EDS3090PG/3091PG series, generates positioning current through PGH injector, and EDS195P cooperates with measuring pliers to locate the fault branch;

Scenario 2: In conjunction with the installed equipment fault location: EDS3090/3091 series, using existing detectors such as BENDER IRDH575 to generate signals, only the evaluation instrument and measuring pliers are needed to complete the positioning;

Scenario 3: Measurement of residual current in grounding system: All models support it. Wrap the branch cable with measuring pliers and directly read the residual current value.
