  • Current and Voltage Unbalance- causes and counter

    Any deviation in voltage and current waveform from perfect sinusoidal, in terms of magnitude or phase shift is termed as unbalance. In ideal conditions i.e. with only linear loads connected to the system, the phases of power supply are 120 degree apart in terms of phase angle and magnitude of their peaks should be same. On distribution level, the load imperfections cause current unbalance

  • Pneumatic Testing of Low-Voltage Cable | TD World

    The diagnosis “leak/no leak” is based on the pressure drop over time, which is monitored from the moment air injection ends. The test duration is a function of the specific time of each cable that is detected at the first step. This technique is applicable to bundled cables with several phase conductors that can be connected in a loop.
