Computerized LCRTZ Test System with 8 Pin Scanner
This Mode is ideal for fast and fool proof testing of COILS AND SMALL TRANSFORMERSlike SMPS transformers, Telecom transformers (HYBRID, POT CORE, RM-CORE), Pulse transformers, Automobile Coils , etc. The system scans at one stroke, all the windings of a transformer or assembly and tests as per definition of test procedure. The test procedure can be pre-programmed and stored under User friendly menu driven software. Any semiskilled and unskilled person can be engaged for actual testing purpose. Can Select test frequency, pin number, parameters, test conditions, limits for each test. Test any pin to any other pin any defined parameter.
Test Parameters include:
Inductance, Capacitance, DC Resistance, AC Resistance, Impedance, Unbalance, Transformation Ratio, Winding Phase / Polarity. Programmable winding selection. Test any of following parameters and test conditions. S8: 8 pin scanning with 8 individual shorting relays to arrange 1 row of shorting .
Shorting provision: (For measurement of series aiding and for leakage inductance test )
In addition to multi-pin scanning the system has 1 row of shorting relays to short between any two or more defined pins . Where ever you need programmed shorting, define in your test procedure. This shorting is very handy for testing parameters like Impedance and leakage inductance. With the help of these two rows you can also make two windings in series for measurement.
The instrument has 2 pairs of connections. One pair for drive and the other pair for sense. This separate connection can be utilized for testing transmission / transformation parameters. You will be able to test transformation ratio.
Though impedance is 2 pin test, it also involves connection of load impedance or load resistance. If you are testing impedance only, you can connect the load impedance permanently to the test jig. However if you want to test multiple windings and other parameters along with impedance, you can use the shorting provided in the system.
Winding Polarity Test:
In addition to Transformation ratio test, the system also checks the polarity of winding
This test calculates the percentage unbalance of the previous two tests. You can measure unbalance of Inductance, Capacitance, Resistance and Impedance. If the individual readings are R1 and R2 then
UNBALANCE= (R1-R2) x 100
