Third-harmonic Induced Voltage Generator

As a renowned company, we are engaged in manufacturing, supplying as well as exporting a wide range of Third-Harmonic Induced Voltage Generator to meet the demands of our clients. The product is designed based on Chinese standard (GB311-61) and original Electricity and Water Authority released (electric equipment prevention test regulation) in January 1985, and to meet the requirement of electric system to high voltage transformer multiple frequency inductive withstanding voltage test equipment, it is widely used AC withstanding voltage test of electric system 35-220kV level series-excitation type voltage transformer,to verify the strengthen of transformer main,secondary insulation,and do induction test for electrical machine and small transformer winding in the same time as welli also used as short time operating 150Hz power supply.

Features:
Use three-core and five post structure, select the magnetic flux density of iron-core is above saturation, to make the sum of fundamental wave potential in secondary winding of aperture connection as triangle is zero
The equipment has over-current protection; If happen over current or breakdown problem during voltage rising and withstanding process, contactor is cut off and main circuit to do protection.
Zero startup protection function, can not start until regulator is at zero position.
Withstanding voltage time is up, it alerts with sound and light, rotate the hand wheel reversely until regulator goes back to zero position.
