STEP 16. Determine Placement of Current Transformers (CTs)
DO NOT INSTALL CTS UNTIL PROPER LOCATION AND PHASING HAVE BEEN DETERMINED.
Each LSP is supplied with one set of two (2) 200-amp current transformers (CTs). The LSP is equipped
with leads for these main CTs as well as leads for an optional set of auxiliary CTs which is available for
purchase from Lumin. Most LSP installations do not utilize auxiliary CTs and use the main CTs to
measure the total consumption of the electrical panel(s) backed up by a battery. In this typical
installation, the CTs are placed on the feeders from the Microgrid Interconnect Device (MID) or
Automatic Transfer Switch (ATS) to the electrical panel, as shown in Figure A.
If your installation is configured
differently than shown in Figure A or if
your installation will utilize auxiliary CTs,
consult the Lumin CT configuration
guide for CT placement information.
