  • High Voltage Gas Insulted Switchgear (GIS) Field Testing

    Sep 18, 2019DC voltage withstand testing is not recommended on a completed GIS. However, it may be necessary to perform a DC voltage withstand test on power cables connected to a GIS. these test voltages would, by necessity, be applied from the end of the cable opposite to that of the GIS, therefore subjecting a small portion of the GIS to the DC voltage.

  • What is the peak voltage at the tips of a dipole antenna

    P = V 2 / R 100 W = V 2 / 4000 Ω 100 W ⋅ 4000 Ω = V V ≈ 632 V. This is an RMS value. Knowing that our transmission is approximately sinusoidal, then the peak voltage is something like: 632 ⋅ 2 = ± 894 V. From the above equations, we can see that power is proportional to the square of voltage: P ∝ V 2.
