Biddle 577500 Energized Winding Resistance Tester. Measures the winding resistance of transformers, chokes, induction coils, heater coils, generators and motors both single and three phase.
The Biddle 577500 / 57J Energized
Winding Resistance Tester is used for measuring the DC resistance of
AC energized windings, thus enabling the determination of winding
temperature rise while the windings are operated under actual load
conditions. The Biddle 57J is suitable for measuring the winding
resistance of transformers, chokes, induction coils, heater coils,
generators and all types of motors where there are no brushes in series
with the circuit being measured. Measurements are possible on either
single phase or three phase, three wire equipment.
The Biddle 577500 / 57J Tester is a modified Wheatstone bridge and is
used as such on energized or de-energized samples. The Biddle Tester is
completely self-contained and measurements are made by balancing the
bridge by means of the measuring dials and the null detector. Resistance
readings are taken directly from the Biddle 57J, no calculations or
multipliers are necessary.
For measurements on windings of a higher current rating than that of
the Biddle 577500 / 57J Energized Winding Resistance Tester, a high
current adapter, catalog number 577510 is used to increase the tester rating. The adapter is
connected to the tester by means of a single cable and an MS type
connector. Details of the ratings are given in the specifications. The
Biddle 577500, when used properly, can make measurements to determine
actual temperature rise with an accuracy of better than one half degree
centigrade.
