In the meantime, most power grids were composed of AC (alternating current) distribution, so there was little demand for DC (direct current) distribution.
However, in recent years, DC metering has been in the limelight due to the spread of DC circuits with many advantages such as easy grid connection with distributed power systems,
low loss, and miniaturization of power equipment.
In particular, the demand for DC distribution facilities such as renewable power generation, electric vehicle chargers, ESS (Energy Storage System),
and residential DC distribution systems is increasing, and with the significant increase in microgrid and digital loads,
it is expected that DC load will expand to 50% of the total power load.
With the opening of the DC power grid era, energy cost reduction through energy efficiency is the most urgent issue in terms of management from the point of view
of energy users or managers. This is something that should be pursued first.
To this end, accurate measurement and analysis of power consumption and efficiency (loss) for DC loads as well as AC,
and establishment of management measures are very important in various aspects such as energy efficiency,
management improvement, and greenhouse gas reduction.
DC metering is used in specific applications to measure, collect and store real-time data of DC power.
DC metering allows business owners to monitor generation and reception power usage to reduce energy costs or verify the
energy integrity of a facility..etc and they can achieve certain management goals. They are used in a variety of industries such as solar systems,
EV charging stations, battery energy storage systems (BESS), cell towers, data centers, and Light Rail Transit.
DC circuits are growing noticeably with the rise of renewable energy applications,
and the greatest demand for DC metering is in energy applications such as electric vehicle charging stations,
solar panels, DC data centers, and DC microgrids.
Monitoring these applications can track energy production before conversion or loss after conversion,
measure efficiency, and track performance. J&D Electronics offers an all-in-one DC metering solution including the Sensway-DCS series.
Offering features including watt-hour (Wh) monitoring and data logging, the DCS series can track a DC system's performance across multiple parameters.
