2. Advantages
1) Safe and efficient detection
Alternative power frequency withstand voltage: Traditional power frequency withstand voltage testing equipment is bulky, consumes high energy, and poses a risk of damage to cables. The ultra-low frequency tester is small in size, light in weight, and low in power consumption. VLF Hipot Tester can achieve insulation detection effects equivalent to or even more sensitive to power frequency withstand voltage while significantly reducing test voltage and capacity, greatly improving the safety and convenience of on-site testing
Non destructive testing: Its low-frequency characteristics greatly reduce the potential cumulative damage risk to equipment insulation, It’s more suitable for old equipment or condition assessment.
2) Accurate diagnosis of insulation defects
Ultra low frequency signals can more effectively penetrate the insulation medium of equipment, and are more likely to trigger deep or distributed defects such as water branches, air gaps, delamination, and moisture. VLF Hipot Tester can better reflect the true insulation condition of equipment under AC operation than DC withstand voltage.
3) Intelligence and Easy to Operate
Automatic control: Equipped with a built-in microprocessor, it automatically completes the entire process of boosting, stabilizing, timing, step-down, and data acquisition.
Intuitive display: The large screen LCD displays the test voltage, current, frequency, time, and waveform in real-time.
Multiple protection: It has complete protection functions such as overvoltage, overcurrent, flashover, and grounding to ensure the safety of equipment and personnel.
3. FAQ for VLF-50KV Hipot Tester:
1. How long is the experimental time?
Generally, customers will test for 5-15 minutes. If it is a new cable handover test, it will take about 60 minutes.
2. When should we use the standard capacitors we are equipped with?
If the cable length is short (less than 300 meters) and the test capacitance is less than 0.05μF, it cannot boost normally, please parallel the high voltage capacitor.
3. How to choose the suitable models for test?
Please make sure that the capacitance of test products is below the instrument rated capacitance . The waveform will be influence if the capacitance of test products is too small and the instrument can not normally output when it below 0.05µF. 0.05µF capacitor in parallel to auxiliary output.
