Product Description
Working principle of VLF
The ultra-low frequency insulation withstand voltage test is actually an alternative method of the power frequency withstand voltage test. When conducting power frequency withstand voltage tests on test products such as large and medium-sized generators, motors, and power cables, because their insulating layers exhibit large capacitance, large-capacity test transformers or resonant transformers are required. Such huge equipment is not only cumbersome and expensive, but also very inconvenient to use. In order to solve this contradiction, the method of reducing the test frequency is generally adopted in the world, thereby reducing the test power capacity. Many years of theory and practice at home and abroad have proved that using 0.1Hz ultra-low frequency withstand voltage test instead of power frequency withstand voltage test can not only have the same equivalence, but also greatly reduce the size of the equipment and the weight. The theoretical capacity It is about one-fifth of the power frequency, and the operation is simple.
Introduction
---Quick Measuring 35/60/80KV High Voltage Cable Testing Equipment 50KV VLF AC Hipot Tester/VLF Generator
Ø VLF Tester is designed and manufactured for electrical equipment very low frequency withstand voltage test.
Ø Very low frequency withstand voltage test is essentially an alternative of power frequency withstand voltage test. It is much smaller, lighter and portable than power frequency withstand voltage tester. It is proved home and abroad that 0.1Hz ultra-low frequency withstand voltage test can replace power frequency withstand voltage test.
Ø It can be applied for 10kV, 35kV, 300MW thermal power machine, 10kV, 35kV power transformer and other electrical equipment

Ø Data of current, voltage and wave form can be directly sampled at high voltage side, so the data is real and accurate;
Ø Over-voltage protection: If the output exceeds the set limit of voltage, the instrument will shut-down to protect itself; the actuation time is less than 15ms;
Ø Over-current protection: it is high-low voltage dual protection in the design, the accurate shut-down protection can be made according to the set value at high voltage side; If the current on low voltage side exceeds the rated current, the instrument will take shut-down protection, the actuation time are both less than 15ms;
Ø A high voltage output protective resistor is provided in the voltage boost body in the design and this eliminates the need of additional protective resistor connected outside;
Ø As a result of high and low voltage closed-loop negative feedback control circuit, the output without capacities rise effect;
Ø High-voltage control part adopts innovative light control HV switching unit, control is accurate, safe and reliable;
Ø With color man-machine interface touch control plus controls modular software operating system, precise and intuitive;
