ELECTRIC SUB METER.

An electric sub-meter is a device that measures the amount of electric energy that has been consumed by a residence, a business, or an electrically powered device. They are typically calibrated in billing units; the meters usually measure your electricity consumption in terms of kWh or kilowatt-hours. These meters usually give a reading in numbers. Electrical submetering involves the installation of power meters that can measure energy usage after it reaches the primary utility meter. Submetering offers the ability to monitor electrical energy usage for individual tenants, departments, households. This device monitors the account for their actual energy usage.

The main purpose of using an Electric Sub Meter is to measure and monitor electrical energy in single-phase environments such as in both indoor and outdoor. An electric sub-meter enables to manage and monitor the electricity usage. The sub-meter is installed downstream from the main meter and does not replace the main meter. The way the electric sub-meter works are that the main meter will record the total utility consumption for the entire property, while the sub-meter only records a portion of the consumption in the sub-metered area. This means that the sub-meters energy consumption is a part of that recorded by the council meter.

Electric sub-meters are suitable for a variety of setups, like, backyard rentals, student accommodation, vacation rentals, business parks, apartment blocks, complexes, and more. Sub-meters can be used to measure electricity usage as well as water usage. 

The upsides of using an electric sub-meter are:

• The reverse current and earth load tempering protection.
• The ease of accurate energy measurement.
• Granular in-depth review of facility energy data.
• Better informed to make decisions that can help optimize energy performance.
• Comparison of usage across similar facilities over time.
• The ability to identify and eliminate wasted energy.
• Gives you early access to maintain issues for repair before critical equipment fails.

Energy management is a growing practice among many facilities. Successful energy management requires detailed information on how energy is being used and how it can be saved. This information cannot be achieved easily without any equipment. For much better and effective energy management and monitoring, the facility needs proper equipment to understand. This is the reason why an electric sub-meter is important, it can provide metering, submetering, and monitoring functions that allow facility managers to gather data that allows them to make more informed decisions about energy use.

 The whole process of installing a sub-metering device takes around 6 to 8 hours and requires specific equipment like fuses, terminal blocks, and extra wires. So, it is suggested to hire a professional for this work. There are many brands in the market that sell electric sub-meter. You can get it offline in any electrical store or you can purchase it easily online from any website. Make sure to invest in a top-grade product as it ensures longevity and also, safety.
