NDDBF Series Multi-Frequency Induction Withstand Voltage Tester

Product Introduction

       The Induced Withstand Voltage Test for transformers and instrument transformers is an important test to ensure that the quality of transformers complies with national standards. The longitudinal insulation induced withstand voltage test for inter-turn, inter-layer, inter-segment, and inter-phase insulation of transformer windings is a critical item in transformer insulation testing. Due to the specific characteristics of longitudinal insulation testing, it is necessary to apply a frequency-multiplying power supply device to increase the test voltage between windings, thereby achieving the purpose of the withstand voltage test.

       The Multi-Frequency Induced Withstand Voltage Tester is designed and manufactured by our company based on field experience and customer feedback to meet various customer needs. It is easy to operate, reliable in performance, and well-suited for the requirements of transformer and instrument transformer induced withstand voltage tests.

     The Multi-Frequency Induced Withstand Voltage Tester outputs a sine wave with low waveform distortion, with a waveform distortion rate of <3%. The entire set of the Multi-Frequency Induced Withstand Voltage Tester is compact, provides stable output, and delivers high-quality waveforms. The core component of this tester—the frequency conversion power supply—is controlled by a high-performance microprocessor and features a fully Chinese menu display. It offers high automation, fast and reliable protection, and a user-friendly interface. Please read this manual carefully before use to avoid incorrect operation that may cause unnecessary damage to the test object and the testing device.

Product Features

☆、The Multi-Frequency Induced Withstand Voltage Tester has protection functions such as overvoltage, overcurrent, zero-start, and flashover. The overvoltage and overcurrent protection values can be set according to user needs, and the flashover protection acts when a flashover occurs in the test object to protect it;

☆、The entire Multi-Frequency Induced Withstand Voltage Tester is lightweight, making it convenient for field use;

☆、The Multi-Frequency Induced Withstand Voltage Tester offers both automatic and manual modes, allowing users to flexibly choose based on field conditions to improve testing efficiency;

☆、It can store and remotely print data. The stored data is numbered digitally, making it easy for users to identify and retrieve;

☆、It adopts DSP platform technology, allowing for easy addition or removal of functions and upgrades based on user needs, and also making the human-machine interface more user-friendly;
