Transmission Line Energy Indicator. Johan W. Alexander. US Pat. # 2467648 April 19th 1949, Filed May 2nd 1946. This invention overcomes the problem of standing waves on a transmission line by combining the outputs of current and voltage sampling networks in the same meter after rectification. When current is at a maximum, voltage is at a minimum and vice versa. A capacitive voltage divider is used. |
