1. Application
Portable Very Low Frequency High Voltage Power Tester VLF Test Set is designed and manufactured by FUOOTECH specially for withstand voltage testing of electrical voltage 10kV/35kV/300MW thermal power machine, 10kV/35kV power transformers and lines, and all electrical main equipment.

FUOOTECH manufactures the most portable and easiest to use VLF hipots available. Offering the largest selection in the industry (including CE marked models), voltage ratings range from 30 kV ~ 120 kV with load ratings from 0.5 µF ~ 5.5 µF. FUOOTECH has been the world's leading source for VLF test equipment since 2002.

Very low frequency high voltage power test is essentially an alternative of power frequency withstand voltage test. VLF hipots perform voltage withstand tests and provide the voltage source for diagnostic cable testing. Customers frequently purchase tan delta and partial discharge measurement accessories along with VLF equipment to further extend their testing capabilities.

FUOOTECH provides the largest selection of VLF test instruments, the most powerful and highest voltage models which are durable, economical, and easy to use.

2. Where is VLF used?

VLF testing is used for any application requiring AC testing of high capacitance loads. The major application is for testing solid dielectric cable (per IEEE400.2), followed by testing large rotating machinery (per IEEE 433-1974), and occasionally for testing large insulators, arrestors, and the like.

Even if a utility doesn't adopt VLF for widespread cable testing, one of the best reasons to use VLF is to check installation quality and accessories, like splices. Many failures are due to damage during installation and/or defective workmanship. At the very least, every newly installed or repaired cable should be VLF tested before re-energizing.

5. Functions & Features

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

2). Overvoltage 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.

3). Overcorrect 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.

4). 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.

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

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

7). With color man-machine interface touch control plus controls modular software operating system, precise and intuitive

8). Multi-purpose, can simultaneously measure tested objects capacitance, insulation resistance, leakage current, and AC withstand voltage test
