Tracking Electricity with the Use of Split Core Current Transformers

Given the planet’s dwindling resources, energy needs to be saved—and there are several ways to go about it. One is submetering to make people more conscious of their energy consumption. An article by Bill Fallon posted on Westfair Online reports that individual submetering is now being implemented in Connecticut:

The state’s Public Utilities Regulatory Agency on July 14 issued the technical specifications for new submeters that can micromanage electric bills in buildings where gross averages had held sway in billing.

Multiple-unit buildings in the past often used factors like square footage and number of appliances to gauge electric use. Such broad groupings offered little incentive to conserve, according to Klein, and at the same time, landlords were prohibited by law from submetering electricity to their tenants.

Under new regulations approved by the state Legislature last year, submetering will be allowed in buildings or campuses that are currently master-metered if it is likely to lead to energy conservation. But, all tenants in a single building or complex must be submetered.

Landlords may not make a profit on the energy bills.

Submetering is gaining importance in the effort to track energy allocation and billing that even consumers must understand so they’ll learn how to cut their energy use. Advanced submetering with split core CTs helps people save on energy and cut costs.

Since one end of a split core CT is removable, the bus bar or load conductor doesn’t have to be disconnected during installation. This is why split-core CTs are easy to install, without interrupting power supply or systems.
