VLF-30 High Safety 30kV Generator AC Withstand Voltage Testing Equipment

Introduction:

VLF-30 AC Withstand Voltage Testing Equipment is designed and manufactured for electrical equipment very low frequency withstand voltage test.

VLF-30 AC Withstand Voltage Testing Equipment 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.

Specifications:

Features:

• Data of current, voltage and wave form can be directly sampled at high voltage side, so the data is real and accurate;

• 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;

• 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;

• 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;

• As a result of high and low voltage closed-loop negative feedback control circuit, the output without capacitive rise effect;

• High-voltage control part adopts innovative light control HV switching unit, control is accurate, safe and reliable;

• With color man-machine interface touch control plus controls modular software operating system, precise and intuitive;

• Multi-purpose, can simultaneously measure tested objects capacitance, insulation resistance, leakage current, and AC withstand voltage test;
