SWG-2000 Surge Wave Generator

タイトルまたは説明

Surge Wave generators SWG-series are intended for: 
· Locating distance to a cable fault using high voltage reflectometer ISKRA*3;
· Cable fault location using receiver P***6 or POISK****6M receivers with acoustic method.
 
According to statistics, the most common faults in the three-phase underground power cable occur such as "single-phase breakdown" (breakdown of one of the cores to the cable sheath). Breakdown of this type can be "creeping" (intermittent) (ie recovering insulation up to a certain voltage, which is lower than the operating voltage of the cable), and with the "insulation leakage" (insulation resistance decreases up to tens kilohms - hundreds ohms).
Quite frequent cases of breakdown of the two cores one to another and to cable sheath (line-to-line short circuit).
For single-phase breakdowns developers recommend the acoustic method of finding and identifying the fault location.
For the line-to-line short circuit it can be recommended induction method using GZCH****0 with receiver P***6 or POISK****6M fault location for "loop" with preliminary insulation burning.
Note that in some cases you can use the receiver P***6 or POISK****6M to determine the cable route using a burning signal.
