• Dead and Live Testing for Time-Saving Electrical Testing Solutions

    Electrical Testing Electrical testing procedures are so risky that without using the appropriate testing equipment can cause fatal accidents and, in extreme cases, even death. Therefore, only the relevant qualified professionals should carry out both electrical installation and maintenance testing.

    Electrical Testing

    Electrical testing is simply the critical evaluation of electrical circuits to determine their electrical performance. With respect to the electrical continuity of circuits, these testing procedures are usually split into dead and live testing.

    1. Dead Testing

    Generally, the first form of electrical testing after installation is dead testing, which qualified electricians perform on de-energized circuits. Among this kind of tests include the ring circuit loop test, which helps identify ring circuits in any installation and ensure these circuits do not form radial or ampersand loops — that the loops are actually ring circuits; and the circuit loop test, which helps ensure all circuits in the installation only contain cables conducting from one end of the installation to the other with minimum resistivity.

    2. Live Testing

    Once you have satisfactorily completed carrying out dead testing procedures, you should follow the dead test with live testing procedures. The main live tests are the earth loop impedance test, which helps ensure the resistance (impedance) of the earth cable remains at its optimum value for proper functioning in the event of an electrical fault; and the polarity test, which helps ensure all electrical apparatuses within the circuit are set within their respective recommended electrical polarities for continuous flow of electrical energy

    Electrical Safety

    While electrical testing remains an important practice in the electrical installation and maintenance procedures, you should ensure every time you carry out these tests you use the right electrical testing equipment. Electrical safety measures demand, for example, that you unplug all equipment from the circuit before carrying out any dead testing procedure.

    Other safety precautions you need to adhere to during electrical testing include using the right testing equipment, following standard-certified electrical testing methods and workplace safety procedures, and putting on the appropriate attire.

    Contact a specialized manufacturer of advanced electrical testing equipment to get the most appropriate test equipment built to IEE and IEEE standards for electrical installation. These experts also offer guidance on proper electrical testing procedures so you can plan for how well you can optimize the performance of circuits using the right testing processes.
