14.6.15. GBAL – General Longitudinal Balance
The general longitudinal balance test is intended to measure what is effectively
the Common Mode Rejection Ratio of a transformer designed to connect to a
balanced line. Two measurements are performed each by applying a voltage to
the transformer and measuring the resulting voltage to calculate the CMRR. To
overcome the differences of three standard methods of measuring the CMRR the
GBAL dialogue box has a separate group of terminals X and Y for the first and
second measurements respectively. The preferred method of measurement is the
LBAL test for which Voltech provide a separate test specifically for this
measurement.
This test is suitable for audio & telecommunication transformers and checks the
effective common mode rejection ratio of the transformer.
On selecting "GBAL General Longitudinal Balance" from the available tests
window, a dialogue box will be displayed:
