Rogowski coils (see Sidebar and References 1 and 2 at end) perform passive current measurement and are used in test and measurement devices and power-monitoring activities. Calibration is required to ...
Stepper motors contain coil windings that require resistance measurements. Measuring resistance in a production environment often requires some special circuits that minimize errors. Resistance is ...
Measuring the electrical resistance (ohms) of motors, compressors, and other electrical devices in HVAC systems may seem straightforward. But when the measurements of zero (0) or “OL” (overload) come ...
