VLF Series Very Low Frequency Power Cable Withstand Voltage Tester

Introduction:

• VLF Series Very Low Frequency Power Cable Withstand Voltage Tester is designed and manufactured for electrical equipment very low frequency withstand voltage test.
• A very low frequency withstand voltage test is essentially an alternative to the power frequency withstand voltage test. It is much smaller, lighter, and more portable than a power frequency and withstands voltage tester.
• It is proved at home and abroad that 0.1Hz ultra-low frequency withstands voltage test can replace the power frequency withstand voltage test.
• It can be applied for 10kV, 35kV, and 300MW thermal power machines, 10kV, 35kV power transformers, and other electrical equipment.

Parameters:

1. Max voltage output: refer to Table 1;
2. Output frequency: 0.1Hz, 0.05Hz, 0.02Hz;
3. Measurement accuracy: 2.5%;
4. Positive and negative voltage peak errors < 2.5%RDG+0.3%FS;
5. Voltage waveform distortion: <3%;
6. Insulation resistance measurement error: <2.5%;
7. Leakage current measurement error: <2.5%;
8. Power supply:AC220V ± 10%, 50Hz/60Hz;
9. Environment temperature: 0~50°C; Humidity:≤85%RH;

Features:

• It with over voltage and over current protection;
• Data of current, voltage, and wave form can be directly sampled at high voltage side, so the data is real and accurate;
• With color man-machine interface touch control plus controls modular software operating system, precise and intuitive;
• Multi-purpose, can simultaneously measure tested object's capacitance, insulation resistance, leakage current, and AC withstand voltage test;
