40A 3 Phase Winding Resistance Tester

Short Description:

ITEM: RUN-DCR340AS

This test equipment has Three-Phase simultaneous test function, Magnetic Augment Function, and Degauss Function.

The winding resistance tester has the functions of three-phase simultaneous power-on, independent current and voltage sampling, simultaneous measurement and display of three-phase resistance and three-phase unbalance rate, so as to greatly shorten the test period of transformer DC resistance and solve the problems about long time consumption for DC resistance measurement of each tap winding in power transformers.

SERVICE: The instrument will be repaired and replaced free of charge for product quality problems within one year from the date of purchase, and will provide lifetime warranty and

technical services. If you find any abnormalities or malfunctions in the instrument, please contact the company in time to arrange the most convenient solution for you.

Ⅳ: Functional Characteristics About The DC Resistance Test:

1. For large transformers whose five-column core and low-voltage windings are connected in delta, the instrument can use the method of high and low-voltage series excitation for testing. The instrument automatically connects the magnetizing circuit of the windings, which can quickly and accurately test the DC resistance of the low-voltage windings.

2. 7 inch high resolution LCD touchscreen, easy on-site operation. Good visibility even under strong light.
3. The instrument is equipped with three-phase test function, in order to complete the three-phase direct resistance measurement in one connection of the star-connected winding, and automatically calculate the three-phase unbalance rate, which greatly saves the measurement time and improves the work efficiency. The phase-by-phase test function can also be used to perform phase-by-phase tests on transformers with YN and D(Y) connections until the test is completed.
4. Comprehensive protection circuit and sound discharge alarm, clear discharge indication.
5. Easily set the test winding, tap position, phase, test temperature, converted temperature etc.
6. Internal data storage up to 100 sets.
7. RS232 port and USB Port for data storage and PC communication.
8. Built-in high-speed micro printer.
