A system and method is provided for ground testing of a yaw system of a nacelle prior to erection of a wind turbine. Such a system includes a pressure sense die located between a media seal and a conductive seal. The integrated high voltage capacitor further includes capacitance uniformity structures located at least partially within the insulator and a second capacitor plate located over the insulator. The casing includes a pair of side panels and a top panel connecting between the pair of side panels. The first flywheel is mounted to the crankshaft assembly to a first side of the crank throw for rotation with the crankshaft assembly about the rotational axis. In case that a single transport stream unit is divided and then recorded across two sectors, header information of the preceding sector including management information which is created corresponding to each transport stream unit is generated, and the size of the header information and transport stream units to be recorded in the preceding sector is compared with the size of a sector.
