These energy savings would reduce emissions by 4 million tons of CO2, or the emissions of over 1 million cars, per year. For an individual building installation, a peak power reduction of up to 15 percent can be achieved by using Emax 2 in place of traditional breakers.
Breakers have been traditionally used to increase safety and protect electric circuits, but with this innovation they find use in energy savings as well.
Breakers like the Emax 2 are used where protection and control of large amounts of energy are used in a low-voltage environment like industrial and commercial buildings, data centers or ships.
Due to energy savings, the Emax 2 breaker will typically pay for itself within a year, the company claims.
The breaker contains a protection trip relay with an integrated power controller that measures and evaluates energy consumption, then manages the loads to maintain or reduce the peak power usage as determined by the user. This will also help prevent blackouts since the root cause is often peak demand exceeding supply.
To manage energy, the electricity supply to non-essential equipment is switched off and back on again as soon as acceptable power levels are reached. Intelligent decision making is achieved by a built in controller and software that uses complex algorithms to decide when it is appropriate to switch the power while maintaining the overall functionality or productivity of the connected equipment.
The breaker also has a communication module that allows it to share vital consumption and system reliability data directly with smart grid and other protocols.
Tarak Mehta, head of ABB’s Low Voltage products division, said, “Because breakers are all around us, the total energy savings potential is massive. It’s a great example of how we can use smart technology to reduce energy wastage. This is good news for the environment and for our customers who can achieve significant cost savings by switching to our new device.”
In 2012, ABB invested about $1.5 billion in research and development and continues to employ 7,000 technologists worldwide.
ABB invests in tidal turbine company Scotrenewables
Recently ABB Technology Ventures (ATV) has led a $12 million investment in Scotrenewables Tidal Power, a provider of tidal turbine systems, to support the rollout of a new hydrokinetic device and to expand ABB’s renewable energy assets.
