AC Control Relays and Wire Lengths
AC Control Relays and Wire Lengths
(OP)
I remember an EC&M article back in the '80's about problems with AC control relays having long wire connections. The article included tables based on wire size, and probably voltage, and provided recommended maximum wire lengths for use with AC relays to avoid disruptive levels of capacitive charging current between two wires that would interfere with relay operation. The Rotork Electric Valve Actuator catalog from that era also discussed the problem, and recommended using DC control relays in their actuators for long control wiring runs.
I've never seen this discussed anywhere else. Can anyone describe the problem in detail and recommend tables based on testing different wire sizes and types?
