SXCS-III Transmission Line Test System is designed to test various parameters of HV transmission line for power station, substation, and laboratory. It is also suitable for all the power supply detecting by electrical generator under power failure conditions.
This system contains below units:
√ Power Inverter
√ Isolation Transformer
√ Transmission Line Parameter Tester
√ Accessories
Features:
√ LCD touch screen. English interface, easy to use.
√ Variable frequency technology, precise measurement.
√ High anti-interference ability, power source generated by build-in power module, frequency can be changed to 45Hz or 55Hz. Advanced filter technology to avoid all kinds of interference signal from on site environments. Test precisely and accurately.
√ DSP High speed processor
√ Easy connection. To complete all the parameters' measurements by one time test leads connecting only.
√ Mass memory, the test results can be stored and print easily. The test data can be exported via USB and generated to test repot.
√ Test fast and accurately. Max. output current 30-40A, the impedance parameters of short distance cable line also can be measured accurately.
√ Build-in power frequency theoretical value of overhead transmission line. User can check the theoretical reference value according the given parameters (cable's type and specification, cable's diameter, divided amount, ground wire type and etc information) in the build-in database. It's easy to contrast with theoretical value and improve these test results are accurate indeed
√ Power Inverter
1) Input source: Single phase AC 220V±15%, 32A, 50Hz±3%
2) Source output: Symmetric power frequency or three phase voltage (or single phase output from paralleled three isolation transformers)
3) Output voltage: 0~250V/0~750V (selectable)
4) Output current: 250V position /0~8A . Max. 40A @ 50V below(max. 100A @paralleled output)
5) 750V position /0~2A. Max. 8A @ 250V below
6) Output power: 3×2kVA(every phase)
7) Output frequency: 50Hz, 40Hz /60Hz(or 45Hz/55Hz)
8) Output frequency dispersion: <± 0.2 Hz
9) Output voltage waveform: standard sine wave, distortion <3%
10) Output voltage asymmetry degree: <1%
√Working conditions:
1) 40Hz and 60Hz should be applied in the frequency test when power frequency inductive voltage or current was in the test circuit, to avoid power inverter from damage if interference current was adding with test current.
2) To test impedance parameter @250V position, if the inductive current of any phase was over 20A (no matter positive/negative/zero sequence wiring), the larger capacitance variable frequency power inverter (option) should be used. Or to adopt pilot frequency which has three phases paralleled output function to test each of phases. Positive sequence impedance measuring adopts offside short circuit non-grounded method, three phases to be test one by one. If zero sequence impedance measuring, offside short circuit wire connecting method is same with standard. The anti-interference ability can be improved to 50A and higher.
