The use of industrial electrical equipment requires the mandatory installation (connection) of its grounding. The procedure is carried out by qualified electricians, licensed specialists who must have the appropriate official permit allowing them to work with high voltage networks.
The installed grounding must undergo mandatory testing for compliance with the established operating parameters. For this purpose, metal bond measurement is carried out, characterizing the quality of the contact connection of grounded electrical equipment with a direct ground loop itself. The technological operation includes:
- Checking the continuous integrity of the entire grounding circuit.
- Measuring the resistance of the grounded part of the equipment and the bus closest to it.
- Determination of the difference potentials between the equipment housing and the grounding point.
Checking all of the listed parameters is considered mandatory. Based on the results obtained, a conclusion is made about the possibility of further operation of the equipment, the need to carry out capital repairs or ongoing work to restore the grounding circuit.
Advantages of measuring metal connections
Carrying out routine measurements of metal connections on an official contractual basis , ensuring the fulfillment of the following conditions:
- Availability of appropriate permits and licenses.
- Carrying out measurements using high-tech certified equipment and instruments.
- Departure of a team of specialists to the specified address at a time convenient for clients (weekends or non-working hours).
- High professional level of electricians.
- Provision of documentation (acts and inspection results) of the established form confirming the conduct of metal communication measurements .
- Free consultation on issues of quality and wear of the grounding circuit.
Work must be carried out after the conclusion of an official contract, which provides quality assurance and compliance with established legal standards.
