1. Introduction to Leakage Reactance Testing
M4110 Leakage Reactance Interface
This optional interface contains the circuitry necessary to convert the voltage
and current, measured during a Leakage Reactance test on a transformer, into
a form that can be measured by the M4100 Instrument. It also contains a
variac so that the proper test voltage can be obtained. The Leakage Reactance
test cannot be made without either this Interface or the M4130 Leakage
Reactance Module, and the accompanying software. It also requires an M4000
Insulation Analyzer.
When using this interface, the standard M4000 safety switch and safety strobe
are used. The necessary current and voltage cables are provided for connection
to the transformer, along with the necessary software, so that this becomes a
self-contained kit for this test. The user is only limited by the size of the variac
provided.
