In this case inform the person in charge who should inform the Megger service to resolve the problem. The instrument may only be operated when the malfunction is resolved. - Page 8 EN 50191 and national standards and regulations must be strictly adhered to. The SWG 1750 C/CD generates a dangerous voltage of up to 32 kV. • The test system may not be operated without supervision.

Page 9: Technical Description
When combined with a reflectometer and an ARM filter in a test van environment, the SWG 1750 C/CD can also be used for pre-location of cable faults by means of the arc reflection measurement (ARM) and / or the current decoupling (ICE, Impulse Current Equipment) method. -

Page 15: Preselecting Surge Level
Commissioning Step Action Connect the screen of the HV connection cable to the earthed screen of the defective cable (operational earth). The screen of the HV connection cable should be fastened as close as possible to the position at which the screen of the cable under test is led out of the termination. -
Page 16: Switching On
Commissioning Switching On Requirements In stand-alone mode the SWG 1750 C/CD can be switched on immediately after all connecting lines have been fitted (the white ON-/OFF-button lights up). To transfer a device permanently fitted into a test van into this state, the test van’s system control panel has to be switched on first. -
Page 17: Operation
Operation Operation Setting of the Surge Voltage Basic principles In particular when pinpointing a cable fault it is vital that the maximum amount of surge energy is utilised, because the discharge energy and the loudness of the "bang" impact proportionally on the fault location. The surge energy depends directly from the set surge voltage. - Page 18 With a view to the optimum energy efficiency (see previous page), setting the voltage regulator to <50% is not very practical (except in the lowest surge level). Instead of this the SWG 1750 C/CD should be switched off and a lower surge level should be selected (see page 15).

Page 19: Adjusting Surge Sequence
Operation Adjusting Surge Sequence The surge sequence can be adjusted using the control knob . Automatic surge decoupling is switched off on the left limit stop on this control knob (single shot mode). This setting is to be selected for the cable fault location in combination with a connected reflectometer. -
Page 20: Operating Modes
Procedure Once the required surge sequence and the surge voltage have been set (see previous sections), the SWG 1750 C/CD immediately starts continuous decoupling of the surge pulses in the defective cable. The fault position can then be located with the aid of a suitable surge wave receiver (such as, e.g. -
Page 21: Pre-Locating A Cable Fault (Single Shot / Charging)
The devices required for this (reflectometer, ARM filter) are usually installed together with the SWG 1750 C/CD on an assembly trolley or in a test van permanently wired to each other. To perform pre-location based on the current decoupling method, two available individual devices (SWG 1750 C/CD and a matching reflectometer) can also be temporarily connected to each other. -

Questions and answers
The Megger surge not automatically thumping
The Megger SWG 1750 C surge may not be automatically thumping due to one of the following reasons:
1. Plug Connector Issue: The HV connection cable's plug connector may not be properly fastened to the HV output, or the locking screw may not be tightened.
2. Auxiliary Surge Attachment Connection: For the CD version, the plug connector or dummy plug for the auxiliary surge attachment socket may not be properly fastened or its locking screw may not be tightened.
3. Rotary Switch Issue: The plug-in rotary switch may not be latched correctly into position.
These issues should be checked and resolved to enable proper operation.
