HIGH-POTENTIAL DC AND AC METERS ITV-140R SERIES
High-potential DC and AC current meters ITV-140R series (hereinafter referred to as "meters") are designed to measure DC and AC sinusoidal currents with a frequency of 50-60 Hz and up to 3 mA (ITV-140R-3), 9 mA (ITV-140R- 9) and 30 mA (ITV-140R-30) in circuits at potential up to 140 kV.
A feature of the meters is the absence of a galvanic connection between the high-potential measuring and low-potential indicator circuits, which ensures complete operational safety.
The meters are intended for use as part of indoor test facilities in the temperature range from + 5 ° C to + 40 ° C, relative humidity of the ambient air up to 90% at 25 ° C and pressure from 630 to 800 mm Hg. Art.
Shock, vibration, presence of corrosive liquid vapors (acids, alkalis, etc.) in the air are not allowed at the installation site.
The product can be operated by one operator from among the persons of electrical personnel who have permission to perform work in existing electrical installations with voltages up to and above 1000 V.
The version of the meters corresponds to group 3 of devices according to GOST 22261.
