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.
