Current transformer vs power transformer
WebA flyback transformer (FBT), also called a line output transformer (LOPT), is a special type of electrical transformer. It was initially designed to generate high voltage sawtooth signals at a relatively high frequency. In modern applications, it is used extensively in switched-mode power supplies for both low (3 V) and high voltage (over 10 kV ... 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,
