Product Description

The DGM-1M is a portable light weight instrument used to locate ground fault in DC systems. It consists of a transmitter Unit T-1M and Receiver Unit R-1M. The transmitter is connected to live / non-live floating system up to 300V DC preferably on the DC bus. It then transmits low frequency and low voltage signal in the DC system without affecting the sensitive operation of relays. The transmitted signal is then tracked by receiver to locate the fault feeder and to track it further up to the point of fault. The instrument is fully automatic and detect earth faults / mixing of source at ease.


Floating DC systems are the back bone of any substation. Mal-operation of DC system / non availability of sound DC system can lead to very big catastrophe in the substation. And hence it is a necessity that the floating DC systems in the substation should be free from any faults. The DC Ground Locator DGL-1M helps substation engineers in locating, tracing, pinpointing DC Ground Faults in any floating DC system up to 300V DC in ONLINE condition. The instrument balance the capacitance of DC system automatically and is fully automatic to detect any faults. The instrument incorporates advanced signal processing to eliminate noise in the DC system and is very sensitive to any ground faults. It also helps in tracking mixing of source in dual Battery system.
