The high-tension chamber isdivided into concrete compartments for the oil switches ofthe generators, motor generator sets and the two outgoinglines, and for the measuring instrument transformers andlightning protection equipment.

Thespace between the opposite phases is joined by deadbridging pieces about 40 ft. long. The northern, or Sche-veningen phase, is fed at a point 11.25 miles from Rotterdamby two bare wires, each of 80 sq. mm cross-section (158,000circ. mil) ; the southern, or Rotterdam, phase, is fed by twowires of the same size seven miles from Rotterdam. Both double insulation permits each insulator to be tested inservice at a higher voltage. This testing is carried out dur-ing non-operating periods with a motor-generator set and atransformer equipment for 25,000 to 30,000 volts. A storagebattery locomotive, which hauls the test car, supplies thedirect current from the motor-generator set. The catenary supports on each span or cross-arm are
