Page 11: Placing Into Operation
Automatic impulse triggering is primarily used for pin-pointing a cable fault. The SSG 1100, SSG 1500 and SSG 2100 are equipped with a timer coupled to the mains frequency which allows for automatic impulse triggering with impulse frequencies of 10/min and 20/min. - Page 12 (14). During short term operation, maximum output currents can be found during the burn down process according to the following table. max. output current (IMAX) Range selector switch SSG 1100 SSG 1500 SSG 2100 SSG 3000 in 8 kV position...

3.2 Connection of instrument Observe correct position of connection terminals! (also see Note on page 14) Connection to a single-phase shielded cable Connection of a three-phase shielded cable Connection to a three-phase unshielded cable with neutral Rear view of device - Protective ground connection 2. - Page 14 Preparing test object Isolate the test object Lock against reconnection Make sure that zero voltage condition exists. Insulate nearby items which are under voltage It must be assured that nearby items of the station or cable system under voltage do not result in breakovers or breakdowns, due to applying surge or D.C.

Estabilshing H.V. connection Connect strand of the high voltage connecting lead with the fault afflicted strand of the test object. It is very important that all connections are of low resistance as possible. Bad connections can lead to weldings or contact wear. At the instrument, protective earth and station earth may not be connected with each other. -

First install station earth (blue) on instrument side and tighten knurled nut (23). Subsequently, install H.V. connection and tighten knurled nut (22). Use only the original BAUR H.V. connecting lead suitable for the particular instrument. When replacing parts, check if the accessible mounting screws for the electrode support (25) are tightened. -

5 Options, Accessories and Ordering Information 5.1 Options Intercom SA 32 The primary application of the Intercom SA 32 is as „aid“ for prelocating of cable faults. It allows locating of high-resistance faults utilizing the secondary impulse method (SIM). This allows for transformation of high-resistance faults into low resistance faults. The surge voltage impulse of the SSG is consequently led to the test object via the high-performance resistors. -
