(telescope, power pliers, three-phase adapter, triangular board, probe)
A modern instrument with additional equipment is used for measuring values such as:
1. Alternate voltage and frequencies measurement;
• Voltage between L and N (U);
• Voltage between L and PE, N and PE;
• Voltage between the probe and PE (U);
2. Power supply resistance measurement (Z);
3. Resistance to ground measurement (R);
4. Insulation resistance testing (R);
5. Low - value resistance up to 100 (om);
6. RCD ring testing;
7. Testing conditions for interruption of electric switch overvoltage protection. Loop resistance measurement (Z), determining short circuit power I;
8. Residual current devices performance test.
