Equipment Testing

                                    Low voltage pulse testing                                                                                ARC multiple pulse testing

This device can use the multiple pulse method to measure distance, and only one short-circuit wire is needed. In addition, when accurately locating the cable fault, it can also be switched to the high-voltage flash-over method (pulse current method - ICE), just remove the short-circuit wire and insert the high-voltage output cable into another HV output port. This ensures high energy output during accurate locating, and will not reduce part of the energy due to the multiple pulse coupler, resulting in less clear sound when listening to the fault discharge sound.
