HZ-3310D Three Phase Transformer Winding Resistance Meter 10A With Magnetic

Performance Characteristic

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

2,Measurement scope is wide（0Ω-100Ω）, which can measure transformer, current and voltage transformers etc inductive DC resistance.

3,The display applies 480272 large lattice 65K colour screen, the displayed data is clear and legible.

4,The instrument has perpetual calendar, 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.
