What is the ratio of current transformers in Schneider recloser and sectionaliser?
As standard, inside switchgear tank is installed with 3 CTs for 3 phases current measurement. These CTs are with 2000:1 ratio for N, U, W, RL series. E series is integrated with CT of 1000:1 ratio
However, the above ratio data is for information only. There is no access to CT circuits for customers to measure the secondary currents or use them for a third party device.
Note that N series can be optionally installed with another 3 CT on the other side of the switchgear for customer’s use. These are called additional or extra CTs and the ratio can be requested from one of the following options at time of order
800/400/1; 600/300/1; 400/200/1 and 200/100/1
