The measuring instrument of direct and alternating current ITV-140P allows to measure current of leakage of object at test by a high voltage.
The measuring instrument consists of the high-voltage measuring ITV-140R-BV block and the indicator ITV140R-MI module. The measuring block is connected in a rupture of a high-voltage chain of the test facility and provides measurement and processing of size and a form of the passing current. After processing data in a digital form are transferred on a radio channel to the indicator ITV-140R-MI module. Information with ITV-140R-MI can be a schitana from the module screen, and can be in addition processed by means of the personal computer connected to the indicator module.
The ITV-140P measuring instrument can be used in power for measurement of currents of conductivity of rated sportsmen and limiters of retension, for measurement of currents of leakage of cables and other objects of high-voltage tests, in high-voltage laboratories for high-quality determination of tension of emergence of crown categories, for definition of a form and a range of low-frequency currents of conductivity.
Extreme values of the measured currents are established individually in the range from units of microamperes to 10 A.
