Plug setting multiplier is nothing but a ratio between the actual fault current in the relay operating coil to pick up current(the relay current setting). Relay pick up current= %current setting * CT ratio In other words, the ratio between the CT (current transformer) secondary current to relay operating currentis called … Visa mer In the electromagnetic relay, the current setting can be done by adding resistance value. This action is performed by inserting plugs. The resistances are connected in serieswith the relay operating coil.
