(minimum health and safety conditions to be applied in annex-1 workplace buildings and annexes)

The regulation on electrical indoor facilities published in the Official Gazette dated 21.08.1984 and numbered 18565 by the Ministry of Energy and Natural Resources entered into force by making changes over time. General provisions regarding grounding and grounding facilities in Article 44 of the Regulation and “inspection of protection devices against indirect touching of live parts” are defined in Article 46.

According to the 7th and 10th articles of the regulation on grounding in electrical installations, which entered into force by the Ministry of Energy and Natural Resources by being published in the Official Gazette dated 21.08.2001 and numbered 24500, grounding has been made mandatory and the establishment, operation, inspection, In terms of security, the provisions regarding the safety have been determined. In the annex-p section of the regulation, the recommended periods for the inspection, measurement and inspection of various grounding facilities during the operation period are specified, and it is foreseen that the inspection and measurement of the resistances of the grounding of industrial facilities and commercial centers will be carried out in 1 (one) year periods.

In accordance with the above-mentioned laws and regulations, you can have your electrical installation checked by Dameks A.Ş. in order to carry out accurate and reliable periodic controls and measurements of your facility in terms of life and property safety, especially employees. The controls and measurements to be made by our technical staff, who have all the technical competencies and documents, will be delivered to you with the valid format and approval in all official institution audits.

What actions are taken in electrical indoor installation measurements and controls?

Fault current (rcd) measurement

Tests and measurements will be made at all end consumer points protected by residual current devices. (sockets, electronic devices, machines, etc.) Rcd opening current (ma) and opening time (ms) will be measured and it will be checked whether the protection is in the right current and at the right time.

• - Continuity check

It will be checked by the (r1+r2) method whether the protective conductors are installed from the end consumer points to the equipotential busbar.

• -Insulation/insulation control

Insulation of conductors/cables and floor insulation will be checked with measurements.

• -Grounding facility controls and measurements

Grounding/loop impedance measurement will be carried out at the end consumers, sockets and machines in the facility. The suitability of the protection against indirect touch will be checked by measuring the grounding/loop impedance value at the end consumer points, whether the protective conductor is drawn in the appropriate cross-section up to the end consumer points.

• -Lightning protection facility control

Grounding resistance measurement and control of the existing lightning protection facility in the facility will be carried out in accordance with the current TS EN 62305 standards and will be reported.

• - Panel grounding control

• - Residual current protection control

• - Transformer and transformer oil control

• - Generator body protection grounding control

• - Control of panel, motor and connection points with thermal camera

All energy rooms, meters, distribution panels, branches, cable shafts, generators, ups, motors, machinery and equipment and electrical connections, elevator electrical installation, lighting installation, weak current installation, starting from the low voltage side of the transformer, if any, within the facility, under the control of the electrical installation, Switches, sockets and junction boxes, compensation systems and grounding facility are checked for compliance with current projects and standards, measurements are made.

It is determined and reported whether there is appropriate sizing and protection for all kinds of equipment and machinery in the electrical installation.

In addition to these, thermal camera examinations of the panel, cables and cable connections are made to determine whether there is an overload or unbalanced load.

What is the scope of electrical indoor installation measurements and controls?

• - Detection of electrical elements such as all fuses, switches, residual current protection device (residual current relay), mains socket and ups socket

• - Residual current protection device (residual current relay) tests (detection of tripping current (ma) and tripping time (ms))

• - Voltage drop measurements

• - Measurement and control of the current carrying capacity of the cables in the panels

• - Connection controls of conductors in panels

• - Control of protection of panels against non-electrical effects that may come from outside

• - Control of single line diagram and detailed explanations in panels

• - Control of electrical hazard and warning signs on panels

Controlling the labeling of equipment such as switches, fuses and residual current protection devices in the panels

• - Control of cables in panels and fuse boxes against mechanical effects

• - Checking the suitability of the color coding of the cables in the panel and fuse boxes

• - Control of grounding and neutral busbars in the panels

• - Checking that the grounding conductor has been transported to the end consumer points without interruption

• - Control of panels against external mechanical effects and temperature effects

• - Grounding measurements and controls

• - Loop impedance measurements

• - Insulation resistance measurements

Why should electrical indoor installation measurements and controls be made?

Electrical internal installations may wear out over time, problems may occur in their connections or may lose their function. For this reason, electrical indoor installations should be checked regularly every year in accordance with occupational safety and related regulations. Performing internal installation checks and maintenance on a regular basis provides the following benefits to businesses.

• - It prevents high energy loss. (increases energy efficiency)

• - It prevents the decrease in quality that may occur in production as a result of disruptions and malfunctions.

• - By ensuring employee safety, injuries and loss of life due to electrical accidents are prevented.

• - By determining the weak points of the installation, the service or production of the facility

• - Electrical accidents that may occur may cause material damage. Regular control of electrical indoor installations ensures that such damages are prevented.

• - Improper sizing of electrical installation components and use of inappropriate equipment, uncontrolled use will bring additional costs to the facility. In the controls to be made, such nonconformities are determined and reported, and the operating efficiency of the facility is increased.

At which points in the facility are electrical indoor installation measurements and controls applied?

• - Main board and sub boards

• - External lightning and lightning protection equipment

• - Machines, generators and engines

• - Sockets and boxes

• - Energy cables

• - Earthing and equipotential systems

• - Lighting systems

• - Fuse, switch, residual current relay control

• - Harmonic control

• - Compliance of electrical hazard and warning signs

• - Compliance of the electrical labeling system

In which audits are our electrical indoor installation control reports valid?

• -Occupational health and safety inspection

• - MoLSS official audit

• - Inspections for licensing purposes of official institutions such as the municipality
