  • Acceptance and Maintenance Testing Medium-Voltage

    The main advantage of testing at very-low frequency is that it significantly reduces the size, weight, and cost of the power supply required and thus offers greater attraction for field testing medium-voltage cables. If the test frequency were dropped to 0.1 Hz, the capacitive reactance, as calculated earlier, becomes 1.6 megohms.
