Abstract
PURPOSE: To provide a measurement, by which the troubles before and after the measuring operations are eliminated, by which the quasi-permanent use of metal pellets is made available and by which no influence is exerted upon a human body, by burying a coil in the metal pellets and by applying a voltage between the coil and the metal pellets.
CONSTITUTION: A coil 1 is made of a conductor 1a and an insulating coating 1b and is supplied with a high voltage when the measurements are to be performed. Upon the high voltage application, the coil is buried in metal pellets 3 of an excellent conductor made of a conductive substance such as lead or tin, and the metal pellets 3 are used as a grounded medium. The conductor 1a has its one end connected to one end of a testing transformer 4 at a secondary side thereof. The measurements are performed with the use of an ammeter 6 and a voltmeter 6 which are connected with the primary side of the transformer 4 through a variable transformer 5.
