Thanks for all the feedback todate.
Thoughts so far:
With nominal Line to Line Voltage of 66.0kV rms.
Typical Max line to Line Voltage of 72kV rms.
Max Line to Ground Voltage 41.6kV rms (On 3 phase systems the line to ground voltage is divided by 1.73).
We have determined how high the line to...
We are converting a 1200m section of overhead 66kV to underground (3 x 1C 630mm² CU XLPE). Looking for suitable 66kV Riser Pole polymer arrestors to install at both pole top ends. Can anybody help.
