sähkölisämittari

A sähkölisämittari, often translated as an auxiliary electricity meter or sub-meter, is a device used to measure the electricity consumption of a specific part of a building or a particular appliance. Unlike the main electricity meter that measures the total consumption of a property, a sähkölisämittari provides a more granular breakdown of energy usage.

These meters are commonly installed in multi-unit dwellings like apartment buildings to track the electricity used by individual apartments. This allows for fair billing of tenants based on their actual consumption, rather than dividing the total building usage equally. In commercial settings, they can be used to monitor the energy used by different departments or specific pieces of equipment. Similarly, in larger homes, a sähkölisämittari might be used to measure the power drawn by a specific area, such as a workshop, a rental unit, or even an electric vehicle charging station.

The primary purpose of a sähkölisämittari is to facilitate accurate cost allocation and to enable better energy management. By identifying where electricity is being consumed, property owners and users can make informed decisions about energy efficiency improvements. They can be either self-contained units or part of a larger building management system. The data from these meters can be read manually or transmitted wirelessly for remote monitoring.
