Electrical measurement works and installation of earthing devices --The following measurement and installation works are performed to issue a protocol on electrical measurement works:

1. Measuring grounding resistance. – Measurement of grounding resistance of the grounding facility and electrical equipment.
2. Measuring insulation resistance. – Measurement of insulation resistance of cables, wires, engine windings and other electrical equipment.
3. Measuring the resistance of phase-zero loop. – Measurement of the resistance of the phase-zero loop in the electrical circuit.
4. Designing and installing grounding devices for electrical equipment.
