A method and apparatus to individually detect the cathode to helix current of multiple TWTs sharing a common cathode to helix voltage supplied by a single HV EPC, which provides the capability to determine which tube has exceeded the limit and to adequately protect each helix structure from destruction due to excessive current. An apparatus for detecting travelling wave tube helix current comprises a capacitor having an input electrically connected to a radio frequency signal, an inductor having an input electrically connected to an output of the capacitor and to an input to a helix of a travelling wave tube, the helix of the traveling wave tube electrically connected to a chassis of the traveling wave tube by an impedance, a resistor having an input electrically connected to an output of the inductor and an output electrically connected to the chassis of the travelling wave tube; and wherein a cathode to helix current of the travelling wave tube may be sensed across the resistor.
