ABSTRACT:
An apparatus for determining the operating condition of capacitors of the type used for power factor correction on electric distribution systems is assembled in two sections. A first power supply device supplies an alternating electric current to a de-energized capacitor without removing it from its installed position and a second power measurement device, utilizing a split-core Hall-device, measures the magnitude of the electric current entering the capacitor being tested.
