WebJan 7, 2024 · Sizing is not done based on calculated short-circuit, all of the CT ratios listed would be saturated under a short circuit condition. For example if you're drawing between … WebThe maximum current (I) = 10 A. The CT rating (P) = 5VA. Now let’s solve for the maximum length of #14 AWG leads that will result in a rated accuracy for a 10A secondary current. Solving for maximum total impedance (ZT): P = I²ZT ZT = P / I² = 5 / 10² = 0.05Ω. Solving for the maximum lead resistance (ZW): ZT= ZW + ZB ZW= 0.05 – 0.01 = 0 ...

WebGenerally, when measuring high voltage and high current transformer signals, you use a VT (voltage transformer) and CT (current transformer). The ratios between the primary and secondary rated voltages and rated currents are the VT and CT ratios. For example, if the rated primary current/rated secondary current is 500 A/5 A, the CT ratio is 100.
