Installation for graduation of devices for measurement intensity of an electrical field

The measuring installation for graduation of devices for measurement of intensity of a low frequency electrical field with spherical sensor is offered. The measuring installation represents system of electrodes forming a field combined with the device of smooth adjustment of a high voltage on them. The electrodes forming a field are designed as hemispheres from a spending material and are incorporated with the help of the hinge from a material with small electrical conductivity in a spherical surface, forming the spherical condenser. The spherical condenser allows to receive fields of the large -intensity at a rather small voltage, shields the gauge from influence of, external electrical fields and spending subjects and has small dimensions Correction factor on distortion of an electrical field by the sensor to expect and it is taken into account at graduation of devices for medsuremerit of intensity of an electrical field
