2. Multiply the phase-to-ground voltage by the square root of 2 to convert the rms value of the voltage to the peak phase-to-ground voltage. 3. Multiply the peak phase-to-ground voltage by the maximum per-unit transient overvoltage, which, for this voltage range, is 3.0, as discussed later in this appendix.

Provided is a live overhaul process for a ±800 kV ultra-high voltage DC power transmission line. An operation method of entering an equal potential comprises the steps of: after an equal potential worker finishes dressing according to a clothing specification, climbing to a cross arm along a strain tower, fastening an insulated protection rope to enter a fitting junction at a cross arm side ...
