What Does an Industrial Battery Discharger Actually Measure?
An industrial battery discharger applies a specified load and records current, voltage, time, and sometimes temperature and individual cell voltages. It measures delivered charge or energy to an agreed endpoint. Conductance and impedance tests provide condition indicators, but do not directly establish usable discharge capacity.
What Does a Transformer Turns Ratio Tester Measure, and Which Faults Can It Miss?
A transformer turns ratio tester applies an AC signal to one winding, measures the response at another, and uses the resulting voltage relationship to assess the expected transformation ratio. Depending on the instrument and configuration, it may also report phase displacement and excitation current. These observations can reveal inconsistencies in winding connections, tap selection, or […]
