Chongqing Gold Equipment Co., Ltd. - Resistance Meters

We are offering transformer dc resistance tester.1.1 general introduction:gdzc series transformer dc resistance tester uses constant current source to measure the dc resistance of inductance circuit such as power transformer coil , current transformer coil and so on. The tester has functions of self test, data processing, discharge rapidly, result print and so on. 1.2 functions:1 a new switching power supply technology makes output current more stable and power larger than before.2 the tester has an advanced signal process circuit which has a good performance at anti-noise. Test data is precise and stable.3 the tester has protections to prevent circuit over-current, circuit over-voltage, wrong operation, discharge and so on.4 small size, light weight and more suitable for outdoor using.5 varies levels of output current make measuring range more wide.6 large-screen lcd makes operation easy. 1.3 main technique index:1 resolution: 12 measuring precision: 0.2rgd+2d3 lcd figures display 44 measuring range:1220m200m1.10.520182202004.5k5 rated power supply: ac220v6 temperature -10+40 rh85%

We are offering ground resistance tester, supplied with the new type different frequency ac power supply, it adopts microprocessor to control and process signal, which solve problems of the interference between test lead wires. It is used to test grounding resistance in different places such as substation ground network4power stationmicrowave station10lightning rod10and so on. gddw-iii grounding resistance tester is applied to measure the grounding resistance in power station or generator station with non-power frequency. all test results could be printed by micro printer.
