Cost allocation refers to the use of meters and DAS to submeter and allocate energy usage by department or cost center with a campus or industrial facility. Allocating these costs provides accountability for energy use on campuses and allows businesses to accurate determine the cost of projects and services. For each building or department, the facility manager installs the necessary sensors and meters to isolate and measure the energy used by that department. On a monthly basis, the data from the DAS is analyzed to produce a cost for energy assignable to the department. For most energy and facility managers, there are benefits and payback to investing in the hardware and software to submeter campuses or industrial facilities.
Measure More... For Less
Whether called Multi-Load, Multi Circuit, Multi Channel or even Branch Circuit energy metering, Setra’s line of power meters lower the cost per metering point and measures with more granularity than other metering solutions on the market.
Identify what's going to be metered
Look across the installation and identify the equipment that are to be measured to support energy strategy
Examples: Chillers, Lighting, AHU’s, Tenant Usage
Count up how many CT’s are needed
Match the CT amperage to the breaker feeding the load or use Patrol Flex Coils (up to 1500A)
Single-Phase Service = 1CT
Split-Phase Service = 2 CT’s
Three Phase Service= 3 CT’s
Select Meter Part Number
Take the CT count and select the meter with the right number by matching the CT’s with available inputs
SPM03EDN = 3 CT inputs
SPM12EDN = 12 CT inputs
SPM48EDN = 48 CT inputs
