Product Description

China Price 3 Channel 10A Transformer DC Winding Resistance Tester

I.Introduction

DC resistance of transformer is one testing item which must be tested during ex-work test of semi-finished products and final products, installation, acceptance test and preventive test of electric power department, which can effectively find out material selection of transformer coil, welding, looseness of connection part, missing strand, broken wire etc manufacturing defect and existing hidden problems after operation. In order to meet rapid measurement demand of transformer DC resistance, our company has researched and developed new generation DC resistance testing meter on basis of its own technology advantage. The instrument applies new brand power technology, which is characterized with small volume, light weight, big output current etc. The whole machine is controlled by a single chip microcomputer, which has automatic self-inspection, data process, display etc functions, it also has automatic discharge and discharge audio alarm and indication etc functions. Testing accuracy of instrument is high, operation is easy and simple, and it can realize rapid measurement of transformer DC resistance.



II.Features

1.This instrument can automatically select output current (maximum output can reach 10A).

2.which can measure transformer, current and voltage transformers etc inductive DC resistance.

3.The display applies 480*272 large lattice 65K colour screen, the displayed data is clear and legible.

4.100 groups of data storage, temperature automatic conversion etc functions, data will not be lost after shutdown.This machine is also equipped with the printer which can output and print testing data. "U disk" interface is available, which will facilitate data importing for review.

5.The instrument is equipped with RS485 communication interface, remote control measurement can be realized after upper position computer operation and control software is installed.

6.This instrument is equipped with three same testing functions so as to cope that one line connection of the star type wiring winding can complete measurement of three phases DC resistance, automatically calculate three phases unbalance rate and greatly save measuring time and improve working efficiency. Also apply phase by phase testing function, carry out phase by phase testing for the transformer applying YN and D(Y) connection way, automatically calculate three phases unbalance rate after testing is complete.

This instrument is also equipped automatic magnetic assist function. The high voltage and low voltage series exciting method is applied for testing windings of five columns core low voltage angle wiring transformer. The magnetic assist circuit in the instrument which is automatically connected into windings can quickly and accurately test DC resistance of low voltage windings.

7.This machine has audible discharging alarm, discharging indication is clear and mis-operation is reduced.

8.This machine has protection and alarm function to protect input against misconnection with AC 380v power supply, which reduces damage on the instruction caused by mis-operation. This machine also has perfect back EMF protection arc prevention capability.

9.This machine is characterized with wind applicable temperature, high accuracy, shake resistant, anti-interference, high stability, convenient carrying etc.
