4.5 CT LOCATION
NOTE:- CT Location is not applicable to the DSE7210 / DSE7310 autostart controllers.
There are two possible locations for the current transformers in the system:
1) Generator : The CTs are used to measure and display generator current only. The typical wiring diagrams
in the preceding section all show the CT measuring the generator load. For clarity, an example is shown
below.
2) Load : The CTs are used to measure and display generator current when the generator is on load and
mains current when the mains is on load. The module display automatically changes to display the current
in the relevant instrumentation page. This example shows the CTs in the ‘load’ for a three phase delta
system but the same philosophy is applicable to the other topologies.
