Monitor multiple CT feeds with the LINAM Summing CT. Combine LINAM CT Split-Core Current Transformers and a Summing CT to build an economical maximum demand ammeter that sums up to five individual CT inputs into a single output. This summation solution lets you monitor multiple feeders to understand distribution transformer loading.
The Summing CT is encapsulated in potting compound. The primary and secondary terminals are stainless steel.

In-Service Installation—Use Summing CTs along with the shorting block accessory for electrical load surveys, submetering for department costing, and in conjunction with demand, kilowatt-hour meters. A combination of Summing CTs and the shorting block accessory allow installation when secondary load is present.
