WebCurrent Transformer White Paper The Basics of Current Transformers Ratio The CT ratio is the ratio of primary current input to secondary current output at full load. For example, a CT with a ratio of 300:5 is rated for 300 primary amps at full load and will produce 5 amps of secondary current when 300 amps flow through the primary. WebNov 1, 2004 · I Line =150,000VA÷ (240V×1.732)= 360A. Fig. 3. When solving for phase current, don’t forget to divide the overall transformer kVA rating by 3. You can calculate the phase current of a delta transformer winding by dividing the phase VA by the phase volts: I Phase = VA Phase ÷E Phase.
WebSep 22, 2024 · Current transformers are used for metering- or protection purposes. The primary current rating of a CT must be larger than the expected maximum operating current. Metering CT’s primary current rating should not exceed 1.5 times the maximum operating current. Standard values for the primary current I pr are: 10, 12.5, 15, 20, 25, 30, 40, 50 ...
