Ct shorting switches
WebThe 1-OCP series of Open Circuit Protectors manufactured by Electromagnetic Industries LLP. Is a voltage sensing devices using high speed shorting SCR switches. When the secondary peak voltage exceeds the clamping voltage value, the SCR operates, shorting the C.T. secondary. and reducing the voltage to about 2 volts in less than 1/4 cycle. Webmonitor). Using 18 AWG wire for the secondary means that the current transformer must be less than 18.95 feet from the connected load (37.9 feet divided by two, The maximum distance from CT out to the load and back to the current transformer). This table is based on 5 amp secondary current transformer types. CT Line Wire=Rw Devices (Meter, Relay,
