Connecting Residual Current Inputs
Variant 4: Measuring Residual Current by 1A or 5A CTs and CSH30 Interposing Ring CT
DE80130
Description
The CSH30 interposing ring CT connects 1A or 5A CTs to Sepam™ to measure
residual current:
b CSH30 interposing ring CT connected to 1A CT: make two turns through CSH
primary
b CSH30 interposing ring CT connected to 5A CT: make four turns through CSH
primary.
Parameters
Residual Current Rated Residual Current Measuring Range
1 A CT I
Nr = IN, CT primary current 0.01 to 20 INr (minimum 0.1 A)
5 A CT I
Nr = IN, CT primary current 0.01 to 20 INr (minimum 0.1 A)
DE80131
Variant 5: Measuring Residual Current by Zero Sequence CT with Ratio of 1/n (n between 50 and 1500)
DE80102
Description
The ACE990 is an interface between a MV zero sequence CT with a ratio of
1/n (50 ≤ n ≤ 1500) and the Sepam™ residual current input.
This arrangement allows the continued use of existing zero sequence CTs on the
installation.
