1. Factor (for measuring current transformers) Setting of a factor to adapt the RCMS… to connected measuring current transformers. The following factor setting ranges are available depending on the CT type and the application. When the channel is disabled, this setting menu has no function (display: --). Select: *1 For Bender measuring current transformers (W…, WR…, WS…, WF…, W…AB). For measuring current transformers with a different transfor- mation ratio (e.g. if third-party measuring current transform- ers are connected via a Bender measuring current transformer). If the conductor to be monitored is wound through the meas- uring current transformer several times in order to amplify the signal.1 … *250/2 … /10Examples for the factor determination X = transformation ratio, N = number of turns through the measuring current transformer (wire up)Example 1: Bender measuring current transformers with a transformation ratio of 600/1Factory setting: Factor:1, CT monitoring: on
