SWGB-20-8 Surge Wave Generator with tests <br /><br /> Surge SWGB series-wave generators are intended: <br /> - Finding distance to a cable fault using reflectometer high voltage Iskra-3M; <br /> - Cable fault location using receiver P-806 receivers or POISK-2006M with the acoustic method. <br /> - Testing the insulation of cables and other devices and direct and alternating current machines (50 Hz) of high voltage; <br /> - Burning the defective isolation of cables with its afterburner later; <br /><br /> According to statistics, the most common faults in underground power cable of three phases occur such as "single-phase collapse" (breaking of the cores to the cable sheath). Distribution of this type can be "progressive" (intermittent) (i.e., the insulation recovery until a certain voltage, which is lower than the cable operating voltage), and the "isolation leakage" (insulation resistance decreases to kilohms tens - several hundred ohms). <br /> very frequent cases of discrimination against a dual-core to another and cable sheath (line-to-line short-circuit). <br /> For single-phase faults developers recommend the acoustic method to find and identify the fault location. <br /> For the short circuit of the line-to-line can be recommended induction method using GZCH-2500 with R-806 or receiver location POISK-2006M failures to "bond" with the primary insulation burning. <br /> It notes that in some cases, you can use the P-806 or POISK-2006M receiver to determine the cable route using a recording signal. <br /><br /> SWGB-20-8 parameters <br /> Test kV AC / DC 1-20 <br /> Surge to 20 kV, 1444 Joules (2888 optional) <br /> increased capacity, iF 8 (16 optional) <br /> Number of stages 4 <br /> operating modes: <br /> - Single Pulse manual <br /> - Automatic increase rate 0.4 Hz <br /> Burning, max 20kV, 11A <br /> Afterburner (conditioning failures), max 500V, 22A <br /> Sheath fault location, max 20 kV, 1444 J (2888 J optional) <br /> power supply, 220 (110) ± 10%, 50/60 Hz <br /> Dimensions, mm 1150x610x1000 <br /> Weight, kg 170
