Energy Meter TestingPublished on 24/2/2012 and last updated on Saturday 21st of July 2018 at 07:48:53 PM
We cannot think of life without electricity and when there is electricity consumption there is a need to measure its consumption. Here energy meter comes into picture. In every residence, malls, industry, everywhere energy meters are used to measure the electrical energy consumed. Those consumers which consume large energy needs better technology to manage their energy consumption and need more data to improve their services. Improvement in energy meter technology has increased the value-added features such as remote sensing, LCD display, recording of tempering events, and many more quality monitoring features in it, along with compactness of size. But it has raised the problem of electromagnetic interference which affects the performance of the equipment. So for better reliability, energy meters have to pass through various electromagnetic compatibility (EMC) tests where meters are compared under various normal and abnormal conditions with a laboratory to ensure its accuracy in the field.Please Rate this Article
Standard Tests for Energy MetersThe performance tests of an energy meter as per IEC standards are divided mainly in three segments which include its mechanical aspects, electrical circuiting, and climatic conditions.
- Mechanical component tests.
- Climatic conditions test include those limits which influence the performance of the meter externally.
- Electrical requirements covered many tests before giving accuracy certificate. Under this segment, energy meter is tested for:
- Heating effect
- Proper insulation
- Supply of voltage
- Protection to earth fault
- Electromagnetic compatibility
