DEVICE FOR AUTOMATICALLY ASCERTAINING CAPACITANCE, DISSIPATION FACTOR AND INSULATION RESISTANCE OF A PLURALITY OF CAPACITORS

摘要

An apparatus (Fig. 1, element 10) for automatically measuring characteristics, such as capacitance, dissipation factor and insulation resistance, of each one of a plurality of capacitors. The apparatus includes a predetermined number of test fixtures (38-1 to 38-N), each test fixture being adapted to receive one of the capacitors to be tested, and a plurality of measurement devices (20, 22 and 24) for measuring various parameters. A relay matrix (66), having a plurality of relays therein, is connected such that each test fixture may be connected to one of the measurement devices and to a high voltage source (12) of electrical potential. Also included in the test apparatus is a network (30) for energizing predetermined sequence thereby to connect the capacitor associated with each relay to the desired measurement devices and for controlling the output of the voltage source to apply a predetermined high voltage to each capacitor connected to the source by the energization of a relay. Recording device (26R) associated with the measurement devices for recording the measured values of the capacitor. In the preferred instance the network (30), the controller (26), and the recording device (26R) implemented using a digital computer (not shown) operating in accordance with a program.
