TAF01 & TAF02 Transformer analysis fixtures
Transformer parameters often vary with operating conditions, particularly frequency. When testing a transformer with a PSM Series instrument the conditions are continuously variable from 10mV to 10V peak (200mA peak current) and 100mHz to 2.4MHz. An automatic frequency sweep can be used to measure any ac parameter over a frequency range and the results may be viewed on screen, or printed out as tables and graphs. Also, a PSM Series instrument can detect the frequency from the circuit under test so that the transformer parameters may be measured under actual operating conditions.
TAF01
TAF01 is designed for testing transformers with 2 or 3 windings. Relays within the base unit make the appropriate connections for the test to be made. The base unit accepts customized jigs with ZIF sockets for quick testing of standard transformers, or Kelvin clip leads (supplied), to connect the non-standard transformers. Using the RS232 port of a PSM Series instrument, a PC may conduct a series of tests without any manual input; PC software, CommTEST, can test the measurements against pre-set pass/fail limits.
TAF02
TAF02 has two vertical probes to energise coils or wound transformers without cores. The number of turns of a single winding or turns ratio of two windings may be measured and a shortened turn may be detected by measurement of Q factor. Supplied with Kelvin Clips, test leads or small 'grabber' test leads.
