Product Description

Triple Frequency Induction Voltage Generator

Dary Electric recommends

Product Introduction

We can provide complete sets of products including control equipment and chassis. This generator is one of the basic equipment for performing multiple-frequency induction high-voltage tests on small-capacity power transformers and cascade high-voltage voltage transformers in power systems, power plants, substations, and power distribution networks. It can also be used for multiple-frequency and multiple-voltage tests on various low-voltage electronic and instrument transformers, inductor coils, and electrical appliance coils. Additionally, it can serve as a multiple-frequency power source with a power not exceeding 1 kilowatt for power supply or testing of certain special electrical equipment.

This product is a static frequency conversion device with low noise and small size. It can completely replace traditional frequency conversion units in high-voltage systems.

Working Principle

Three single-phase transformers have their primary windings connected in a star configuration and secondary windings connected in an open delta. When a symmetrical three-phase sinusoidal power supply is applied to the primary side, and the voltage is raised to saturate the iron core magnetic circuit, the content of the third harmonic component in the magnetic flux increases, correspondingly increasing the third harmonic voltage induced in the iron core coils.

The 150 Hz (triple power frequency) induced voltage output from the secondary side of the open delta generator serves as the triple frequency test power supply voltage.When the triple frequency generator is loaded with a load (for example, a YHJC—220 high-voltage cascade voltage transformer), its current changes from inductive to capacitive. Due to the low power factor, the efficiency of the generator is relatively low, generally only about 20%. Therefore, a reactor can be connected to an empty winding of the test object for current compensation to improve the power factor of the entire test circuit.
