Electrical measurements

Electrical measurements are inspections of electrical wiring and power supply system, during which its safety, technical condition and compliance with regulatory requirements are assessed.

Electrical measurements are necessary not only for safety, but also for compliance with regulatory enactments. According to the rules of MK No. 238 “Fire Safety Rules” inspection of electrical wiring, including grounding and lightning protection devices, should be carried out no less than once every 10 years, but at individual facilities more often. The absence of an inspection can lead to risks in fire safety inspections, administrative consequences and difficulties in obtaining insurance compensation, since if the cause of the fire is related to electricity, insurers assess whether the mandatory electrical safety requirements have been met.

Yes, in many cases, electrical measurements are a necessary part of the commissioning of an object or wiring. They certify that the system has been tested and meets technical and safety requirements.

Insulation resistance measurements check the insulation condition of cables and wiring. They help determine whether the insulation is not damaged and whether the system is safe for further operation.

Measurements of the full resistance of the “phase-zero” loop help to evaluate the performance of protective devices in the event of damage. These measurements are important for the safety of the wiring and for automatic disconnection in situations of short circuit or damage.

Grounding measurements are important because the grounding system protects people and equipment in the event of damage. Insufficiently effective grounding can increase the risk of electric injury, equipment damage and fire.

Thermography is an examination of wiring with a thermal imager, which helps to identify overheated connections, congested areas and other defects without disassembling the system. This is an effective method for early detection of potential problems.
