Description

Device of PST-1 transformers of comparison

The PST-1 device is intended for measurement of errors of measuring transformers of current of classes of accuracy from 0,05 and below, let out in accordance with GOST 7746 and GOST 23624 with rated secondary current 1A or 5A, and measuring transformers of tension of classes of accuracy from 0,05 and below, let out in accordance with GOST 1983 and GOST 23625, with a rated secondary voltage of 100, 57 or 33 Century. A scope - checking (calibration) of measuring transformers of current and tension according to requirements of GOST 8.217 and GOST 8.216 respectively.

The device is entered in the State register of measuring instruments of N26825-04 and allowed to application in the territory of the Russian Federation. Certificate of RU.E.34.005.A N 17524.

The device can be used for measurement active and jet making capacities of loading of a secondary chain of the calibrated transformers.
