Computerised LCR TZ Test System

---

Vasavi Electronics, manufacturer of automatic test equipment for transformers, offers a Computerised LCR TZ Test System, Model CVCT-S20. This is ideal for fast and foolproof testing of coils and small transformers like SMPS transformers, telecom transformers (hybrid, pot core, RM-core), pulse transformers, etc. The system scans at one stroke, all the windings of a transformer and tests as per definition of test procedure. The test procedure can be pre-programmed and stored under user-friendly menu driven software. Any semi-skilled and unskilled person can be engaged for actual testing purpose. It 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
• AC resistance
• DC resistance
• Impedance
• Leakage inductance
• Transformation ratio
• Winding polarity
• Inductance un-balance
• Capacitance un-balance
• Resistance un-balance
• Impedance un-balance

Special options for telecom parameters like longitudinal balance, insertion loss and return loss can be opted with custom designed equipment. The instrument is controlled through external PC through RS232C port. The system stores the test results to database tables. The system software works on Windows platform. All the test results will be transferred to a database files with connected file name. The database table is compatible to fox-pro table. One can import these files to other software for creating graphs and other analysis.
