HZ211S-10 Turn To Turn Surge Impulse Tester-Other Transformer Test Series-Huazheng Electric Manufacturing (Baoding) Co., Ltd.

Product Introduction

Its main business is the production, manufacture and sales of electrical equipment and testing instruments.

I. Overview

1.1 Introduction

Turn to Turn Surge Impulse Tester(i.e. Digital interturn test instrument ) can efficiently carry out non-destructive electrical test on the component with some coil windings. Its principle is to apply the same pulse voltage on both coil winding under test and standard one, and then compare their transient waveforms, so as to test the quality of coil winding under test. Transient waveform (i.e. waveform of the damped oscillation occurring in the coil) can judge this winding’s inductance, quality factor, coil turn difference and interturn short circuit; if the winding is equipped with a core, it also can judge its material difference and so on. In the case of applying high-voltage pulse, the occurrence of corona discharge can also judge its poor insulation. In a word, for various elements to indicate the coil quality, their inspection can be completed within a short period of time.

HZ211S-10/HZ212S-10 series Turn to Turn Surge Impulse Tester, which is manufactured by our company, adopts micro computer technology to quantize various parameters of waveform, and then use the intuitive waveform for display and judgment. Its operation is simple, its judgment is accurate, and its degree of automation is high. The instrument is small in size, and light in weight, which is easy to carry.
