The basic terminal block (OAT6DTS) have been tested for short time withstands current of 720A ... SpletSo, here CTR is 20 (100/5 = 20). It means primary current is 20 times greater than the secondary current. For CT 400/5A, CTR = 80 (which is 400/5 = 80), it means primary current is 80 times greater than secondary current.As CT is just like any other transformer, it must satisfy following equation –. T.R = Np/Ns = Is/Ip. pip install pywin32 失败

SpletIf a service has both CT’s and PT’s then the two values are multiplied together to give the billing multiplier. For example if a service has 200:5 CT’s and 2.4:1 PT’s, the multiplier will be 96. This is because 40 x 2.4 = 96. We also know much about CT’s and meters because of Blondel’s Theorem. Splet18. avg. 2003 · As long as one tap of a muliratio CT is used the other taps can be left open.
