VLF (Very Low Frequency) Testers are suitable for testing power cables transformers switchgear rotating machinery and other electrical apparatus.
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 20ms.
3. Overcurrent 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 20ms.
4. A high voltage output protective resistor is provided in the voltage boost body in the design and this eliminates the need of additional protect

product brief introduction Product Introduction
The Test Transformer(ac dc hipot tester) calls the booster it is the basic test equipment used by the power station supplying and distributing the electrical power system and the scientific research unit. Which used in the insulated intension test on all kinds of electrical products electrical equipments and insulated materials testing the insulated level of products discovering the insulated objection of quizzee scaling the capacity burdened voltage.
AC HV Testing Transformer Classification:
There are four kinds of high voltage testing transformer according to the medium points:
1. Oil-immersed high voltage transformer test: large capacity, cheap, convenient maintenance, mainstream products.
2. Inflatable high voltage test transformer : interrupter resistance, and light weight.
3. Dry type high voltage testing transformer: light weight, light volume, can run backward, price expensive.
4. Series type high voltage testing transformer: small volume, low voltage, light weight, easy to transport and install.
warning
1. Test transformer should be applied into use with control unit as for how to use control unit please see Operation Manual of Control unit.
2. Screening wire should be applied into the direct current test to avoid straying leakage. After test discharge rod is applied to release the restored electricity.
3. The end of high frequency voltage filtering capacitance should be connected with the ground wire together with crust of control unit to connect with the earth wire.
4. The whole test should follow the regulation in high frequency voltage test site should pay more attention to the safety of equipment and body.
Designed to measure the winding resistance of transformers, Inductors, generators, motor windings, Tap Changers, Bus bar contacts Etc.
