Electrical measurements

Electrical measurements are carried out in order to check the characteristics of the electrical network and how they meet the standards and requirements. Electric laboratory of LLC "KamaEkspert" conducts measurements of electricity in networks up to 1000V. All the modern measuring instruments necessary for this purpose are in the laboratory, and special normative and technical documentation is being used to record the measurements. These are the works: * Resistance measurements, which are carried out on electrical equipment, electrical devices, power lines and cables, on secondary circuits, whose voltage must not exceed 1000V. * Measurement of the resistance of the "phase-zero" circuit in electrical installations up to 1000V with the TN system. * Measurement of resistance of grounding devices and soil resistivity. * Testing the operation of RCDs, differential current circuit breakers (VDT). * Checking how the ATS is triggered (automatic reserve switching). * Check the connecting circuit between the grounding devices and the elements that require it. * Measurement of touch voltage. * The operation of the releases is checked in switches whose voltage can reach 1000V. * Recommendations for choosing the means of protection in electrical installations up to 1000V. * Thermal imaging control of insulation and condition of contacts in electrical equipment. * High-voltage testing of electrical appliances (rods, transformers, electric motors, insulators, etc.) and PPE: gloves and shoes made of dielectric, voltage indicators, tools for work, etc. * Detection and elimination of damage to cable lines up to 10 kV. Employees of the company LLC "KamaEkspert" in addition to electrical measurements perform a comprehensive survey of the building, make electrical wiring diagrams and offer options that allow you to correctly distribute loads and save energy. These surveys are relevant for facilities that have long been in operation and have a large and extensive energy supply system. In such facilities, as a rule, during operation and modernization, the schemes that exist do not demonstrate the real state of affairs. The whole list of electrical measurements is carried out according to the requirements and norms specified in the documentation. At the end, the electrotechnical laboratory issues to the Customer: * Report on the technical part, indicating the entire protocol package, which is needed for submission to the Interregional Territorial Department of Technical and Environmental Supervision of Rostekhnadzor for the Ural Federal District. Sometimes a separate list of required works is indicated. * Conclusion on the subsequent use of the electrical installation. * Tips that help you fix defects and avoid breakdowns.
