Electrical Safety Inspections

Thermographic Inspection

Under normal conditions in an electrical installation, the electrical current causes heating. These heat losses, which occur as heat energy, are the result of complete functionality in terms of the components that make up the installation and this heating generally remains within safe limits. However, if the installation is not installed correctly, the connections are not complied with, or due to the characteristic of the electrical load passing through the installation or due to incorrect distribution between the phases, this heating may exceed the safe limits. This is a danger to the installation.

Thermographic inspection services provided by authorized inspection bodies are the studies carried out to investigate and detect these hazards. These studies are carried out on electrical wiring components. In the examinations carried out, if there are faulty and poor connections and undesirable contact points between the installation components, they are revealed. These points are also detected if there are load imbalances between the phases, if the installation component is subjected to overloads above its capacity and fault currents are present in the installation. Thanks to these studies, future risks and unexpected situations such as fire or electric shock are prevented.

Theoretically, all objects emit different values ​​of thermal energy depending on the properties of the object. This thermal energy is in the invisible infrared range. This range is between microwave rays and red light. This energy can only be monitored by thermal imagers. These cameras also clearly reveal problems that are not visible to the normal eye but can have serious consequences.

This imaging system is based on invisible infrared (IR) energy (heat), and the overall structure of the image consists of colors and shapes that appear according to this heat energy. This imaging system is also used for security purposes. It is also used in night vision systems, heat-guided missiles and a number of military devices.

However, this imaging system is widely used in the electricity sector to detect problems caused by electricity. In any electrical installation, the heating that occurs during the transition of the electrical current is monitored by thermal imagers and if there is a problem, it is detected.

Cables, contact points, power transformers, capacitors and similar components which are under extreme load are monitored by thermal imager and any problems in the heated points are determined without any other electrical measurement.

The devices used during thermographic examination have a certain temperature range to generate the image. IR (infrared) emissions are detected at the detected temperature point. These IR (infrared) rays have different wavelengths and these devices display different images according to these temperature values. The cameras in these devices capture the temperature difference even at the lowest temperature and generate the image from this difference.

Thermographic inspection services are provided by accredited inspection bodies both in the low voltage range and in the high voltage range. However, the most commonly used area is the low voltage range. The most common situation is that loosened electrical connections produce resistance to the electrical current passing through them. In this case, a temperature begins to form at the connection point. This rise in temperature causes the compound to malfunction. This results in larger system failures and therefore significant costs. At one point, the system crashes.

In the field of high-voltage surveillance, thermal power cameras are mostly used for power transformers. High voltage connections must be checked in order to identify the problem and intervene correctly. In addition, high-voltage power lines and power elements are other measured power transformers.

Our company provides electrical installation measurement and inspection as well as thermographic inspection services. ASTM E1934 standard is taken into consideration in these inspection studies. The full name of this standard, which was updated in 2014, is as follows: standard guide for inspecting electrical and mechanical equipment with infrared thermography. This standard specifies the responsibilities of persons using electrical and mechanical systems, and persons to perform infrared thermographic examination.

Internal Installation Periodic Inspection

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 sprinkler systems, sprinkler system, hydrant system and fire cabinet system are installed.

·         Foam, gas and dry powder stationary extinguishing systems for the transport of water, gas, foam or similar substances

Steel pipes are generally used for pipe installations. According to the flammability classes of building materials, steel pipes are classified as non-flammable, non-flammable, non-flammable and charcoal.

Nevertheless, if regular and continuous inspections and inspections of the piping are not performed, they may leak at a time when it is needed or may not be used at all. Therefore, in order to avoid large-scale damages in the future, it is obligatory to have periodical maintenance of the piping in accordance with the minimum requirements for health and safety regarding the use of construction machinery and equipment in the workplaces described in the legal regulations. This legal obligation is stipulated in the Regulation on Health and Safety Conditions in the Use of Work Equipment.

In the annex of the mentioned Regulation, Regarding Maintenance, Repair and Periodic Controls (Annex 3), the control periods of the installations in operation and the control criteria to be considered in these controls and related standards are explained. In this context, pipe installations, which are part of the fire installation, must be inspected and inspected at least once a year unless a specific period is specified in the standards.

Inspection of Motor Pumps

Motopumps are portable pumps which are generally used by firefighters. It is generally used to discharge water in floods or to intervene in fires and to draw water from sources such as lakes, ponds, seas, cisterns, pools and rivers. Motopomes can work with gasoline as well as some types of electricity. In its simplest terms, the motor pump is a motor-driven pump.

Regardless of what purpose they are used, the motopomes need to be checked and inspected regularly and in the same way as any other machine. The motor pumps are a complete machine and, if not maintained regularly, can inevitably fail at unexpected times. The sooner these malfunctions are intervened, the greater the potential for future damage. During the operation of the motopumps, the most common problems are: the strainers may be worn and worn, there may be wear on the impellers and impeller vanes, or the return bearings of the cups may be defective. These problems result in reduced pump flow, reduced head and efficiency losses of the engine.
