In general terms, maintenance works are the interventions made in order to minimize the equipment malfunctions in the field, extend their service life and maintain the establishment of the establishment. If the conditions required by the environment and the machinery and equipment operating in these conditions are considered in a manufacturing facility, it is very natural for them to malfunction, deteriorate and complete their operating life. Therefore, it is only possible to prevent possible malfunctions or to replace the equipment whose service life has expired.

In this context, electrical internal installations may cause problems in their connections over time, become obsolete or become unable to function. In order to avoid these situations, electrical internal installations should be checked regularly.

This issue is also covered by the Regulation on Health and Safety Conditions in the Use of Work Equipment issued by the Ministry of Labor and Social Security. In accordance with the aforementioned regulations, employees must be protected from the danger of contact with electricity directly or indirectly due to the construction machinery and equipment used in the enterprise.

In the annexes of the Regulation, it is stated that regular inspections of electrical installations, earthing installations, lightning conductor installations and accumulator, transformer and similar electrical installations should be carried out by electrical engineers, electrical technicians or high technicians (Annex 3).

In order to ensure the continuity of operations and production, to prevent fire risks and to prevent electrical accidents, enterprises should have their internal installation controls checked regularly.

Our company, periodic inspections of internal installation control within the framework of electrical safety inspections, in accordance with the relevant legal regulations, standards and test methods published by domestic and foreign organizations. A few standards considered in these studies are:

• TS IEC 60189-2 Low frequency cables and wires - PVC insulated and PVC sheathed - Part 2: Double, triple, quadruple and quintet cables for indoor installations
• TS 12541 Electrical installations installation, maintenance and repair workplaces - General rules
• TS 4915 EN 60669-1 Switches - For stationary electrical installations used in homes and similar places - Part 1: General specifications
