This first test measured the PD up to and including the 33 kV ring main unit (RMU) located at the bottom of the Turbine A Tower, 1240 m away. OLPD Test 2 was then carried out at the RMU at Turbine A to pinpoint the location of the PD source that was detected in OLPD Test 1, using TDR pulse timing measurement techniques as described below. Project OLPD Test 1 was carri
