SEBA KMT GEOLUX GL 660-1 EARTH FAULT LOCATOR

Important control, signal and supply cable systems are monitored by so-called earth fault indicators in order to ensure uninterrupted operation. The response threshold of these indicators is largely variable. Normally, a single core earth contact does not cause any service interruption. In the event of a second earth fault however, the danger of a partial or total breakdown of the installation exists. For this reason, single core earth faults have to be located as quickly as possible. Several years ago, Seba Dynatronic developed the GEOLUX system GL 660 specially for this application.

The new GL 660-1 is a mark II version of the GL 660 permitting fault location up to fault resistances of 150 kOhms. Additionally, the new GEOLUX system features a compensation facility for measurements in cable systems with a high capacitance. This makes the test equipment suitable for large enterprises and power plants, as well as for use in teed control and signal cable networks of the railways and public utilities. It can also be used for fault location in single phase airfield apron lighting cable networks. When using the GEOLUX system, a very low frequency current (5 Hz) is coupled directly to the fault conductor. The electromagnetic field of this signal current, which does not disturb the operation of the cable system, is picked up by an inductive probe leading to an exact location of the earth fault. For easier identification, the signal current can be transmitted at a certain clock rate whereby the transmission time of the generator is indicated on the receiver through a synchronizing circuit. With the help of a newly developed circuit, the cable capacitance can be compensated, making the location of faults with resistances of up to 150 kOhms possible.

Seba GEOLUX GL 660-1 features:

Generator GLS 660-1:

Low-pass filter for direct coupling to live cables up to 660 V AC and 660 V DC.
