1. Application
VLF (Very Low Frequency) AC Hipot Testers are suitable for testing power cables, transformers, switchgear, rotating machinery and other electrical apparatus.

Ultra Low Frequency Dielectric Strength Test is the alternative way for power frequency voltage withstand test. as we know, it is needed huge capacity testing transformer or a resonant transformer for power frequency voltage withstand test to large generator, cables etc. due to larger electrical capacity of insulating layer. The huge equipment is not only bulky but also expensive and not suitable for use. The electricity sector makes some test to solve the problems.

According to theory and test result from domestic and overseas in the past years, 0.1Hz ultralow frequency voltage withstand test can solve this problems and the advantage is not only got same test results but also the instrument dimensions is small and considerably reduced the weight of it .

2. Performance

FTAC Series VLF Hipot Tester gather together with the advanced technology of modern digital conversion, fully computer control, automated boost, buck, measurement and protection. Human intervention can cared out during the automatic step-up process. The main advantages of this hipot test set includes fully electronic, small sizes and light weight, large-screen LCD (clear and intuitive), print output test report, easy to use. It is designed to fully meet the power industry standards. Mechanical approach are used for modulation and demodulation ultra-low-frequency signals but no standard sine wave, some error of measuring and spark discharge in high-pressure part etc, FTAC Series can overcome the shortcoming of these.

4. Functions & Features

1). Data of current and voltage are obtained directly through the sampling of high-pressure side and it is true and accurate.

2). Over-voltage protection: the instrument will shut down to protection within 20 ms when the output voltage is exceeding limiting values of setting.

3). Over-current protection: design for dual protection of high and low voltage, downtime protection can be accurately set in high-pressure side. Shut down to protection times is within 20 ms when the current of low-voltage sides exceeds reacted current.

4). High-voltage output protection resistor design in the body boost and it is no need to additional outside resistor.

5). Closed-loop negative feedback control circuit of high and low voltage.
