    Abstract - (Show below) - (Hide below)

    Will formulate uniform rules regarding performance, testing and rating for coupling capacitors for power line carrier systems on HV overhead power lines in the power frequency range 15 Hz to 60 Hz and a carrier frequency range of 30 KHz to 500 KHz. It also formulates specific safety rules and provides a guide for installation and operation.
