Transformer analyser fixture, TAF01
The transformer analyser fixture TAF01 consists of a relay
switching base unit that accepts plug in module to
interface to transformers.
It connects to the BNC connectors on the front of
PsimetriQ and is controlled by PsimetriQ via the extension
port.
It supports transformers with 2 single windings, or with 1
single winding and one split winding. The winding(s) to be
used for a measurement may be controlled by the front
panel or by communications.
The connections to the transformer may be made either by
a plug in pcb with suitable ZIF socket and resistors, or by
flying leads with cable clips. To use the latter, plug in a
resistance carrier board with appropriate source and load
resistors.
NB it is essential that a source resistor be fitted for
all tests.
The fixture contains high impedance buffer amplifiers that
help to reduce the effect of stray capacitance and
inductance.
