Purpose of the development: The instrument is designed to measure the resource switching high-voltage switches.

Recommended application field: The device can be used for energy associations. Recommended for use in electric networks 6-35 kV. The device can also be used to measure the operating resource dischargers.

Technical characteristic: Supply voltage, V: 100. Power consumption, W: not more than 5. Current Measuring Range, kA: 0,2-31. Overall dimensions: 190 * 160 * 100. Weight, 1.2.

The development stage readiness: Pre-production model is made

Description of the development:
()
The principle of operation is based on measuring the current at the time of switching, and their further transfer to the rated operational current trip switch by introducing weighting factors . Functionally, the device has the following blocks: block normalizing converters , analog-to - digital converter unit of weighting coefficients , the digital comparator unit synchronization , the display unit , power supply unit . Circuit- design solution provides two modes of operation prpibora : first I - setting the initial resource switching device ; Mode II - automatic tracking of resource expenditure switching apparatus. The exhaustion of the resource switching device generates a signal , which prohibits the drive control of the switching device . Measurement error switching resource - no more than one switching nominal operating current. Mode - continuous . For establishing device controls provided . The design of the device to store information in memory is provided an emergency power supply in case of the disappearance of the main supply. Bit indicator - 3 decimal places .
