Technical parameters are key indicators for evaluating the performance of withstand voltage testers, directly determining the instrument's testing capabilities, accuracy, and applicability. Key parameters typically include output voltage range, current range, output power, test time, and accuracy.
Different models of withstand voltage testers have different technical parameters. For example, the 7110 series AC withstand voltage tester has an AC output voltage of 0-5.00KV, a DC output voltage of 0-6.00KV, an AC leakage current of 0-12.00mA, a DC leakage current of 0-5.00mA, an insulation resistance test voltage of DC 0.10～1.00KV, and a resistance range of 1～1000MΩ. The CC2672B high-current withstand voltage tester has an AC test voltage of 0-5kV±5%, a leakage current of 0-2/20/100mA±5%, a timing range of 0-99 seconds, and an output power of 500VA. The VT2008 ultra-high voltage withstand voltage tester has a measurement voltage range of 0–100kV, an output power of 10000VA, a leakage current range of 0–100mA, and a time control range of 1–999 seconds. The Chroma 19052 is a three-in-one model for AC/DC withstand voltage and insulation resistance testing, with programmable output voltages of AC 5kV and DC 6kV, a maximum current of AC 30mA and DC 10mA, and an insulation resistance of 50GΩ/1000V DC.
The ACW output voltage range of the CS9929AX programmable multi-channel insulation withstand voltage tester is 0.050kV～5.000kV, with a maximum output power of 100VA. The DCW output voltage range is 0.050kV～6.000kV, with a maximum output power of 60W. The IR test voltage is 0.050kV～1.000kV, and the maximum insulation resistance is 9.999GΩ [11]. The withstand voltage test output voltage of the HIOKI 3159 withstand voltage insulation tester is AC 0～5.0kV (500VA), and the current measurement range is 0.01～120mA. The insulation resistance test voltage is DC500V/1000V, and the measurement range is 0.5 MΩ～2000 MΩ [14]. The Huayi EST-300 series withstand voltage tester integrates AC withstand voltage (ACW), DC withstand voltage (DCW), and insulation resistance (IR) functions into a single machine.
