SPECIFICATION:

The tester is designed for automated control of ground circuit health of mobile mining equipment at open pit coal mines and other quarries.

The tester retains its technical characteristics at an ambient temperature from -40 to + 45 °С, relative air humidity up to 80% at a temperature of 25 °C and air dust level up to 250 mg/m3.

The tester is installed on the outer side panel of the control compartment of the connection point at open pit mines and serves to monitor health of the grounding wire of the high-voltage line.

The tester monitors the section of the electric power transmission line to the connection point.
