Safety, security and reliability expertise for low and medium voltage distribution products

In the developed world, the Industrial Internet of Things (IIoT) is changing the generation, transmission and distribution of power and electricity. Two-way communication flow enables smarter and more efficient use of resources and gives more control to customers on how and when they use electricity. In the developing world, distributed energy resources (DER) and distributed generation (DG), often in the form of renewable energy are bringing reliable electricity to citizens for the first time.  

The modernization of electricity distribution is exposing grid operators, regulators, suppliers and consumers to new opportunities and challenges. Transmission and power distribution product suppliers now need to meet a new set of IIoT related requirements, such as cybersecurity and interoperability. The influx of DER and renewable energy is increasing demand for proven technologies that can interconnect with the grid in a mutually beneficial way. The advent of data analytics and artificial intelligence is changing the way system operators and consumers are making critical decisions, often without human intervention. And smart power distribution devices are being adopted in smart homes and smart cities at an unprecedented rate.
