Data centers account network data like social network profiles and uploaded media. The U.S. alone stores a third of the world’s data—nearly 900 exabytes (900 billion gigabytes)—in data centers all over the country. With eight Internet users coming online every second, six of them in North America, data centers have to expand constantly to make room.
However, expansions take their toll on the local power grid. According to the Natural Resources Defense Council, data centers consumed a total of 91 billion kWh, enough to power New York’s homes twice over, in 2013. Most of the consumption stems from HVAC systems used to keep the databanks cool. After all, heat is the enemy of sensitive electronics. Continue reading
In days past, most current sensing designs followed only a few basic approaches. With the advancements in technology came a slew of measuring choices, making the selection process a bit more challenging. Should you choose Reflective light proximity sensors? Hall Effect sensors? How about one that uses Eddy current sensing?
Granted, for general applications, any type would likely yield satisfactory results. However, if you’re asking more from your devices, or if you have to work in extreme conditions, some options work better than others. That’s when you need to be concerned about the choices you make.

As a split core transformer, flexible transformer, and AC and DC current sensor distributor, Aim Dynamics is always excited to carry the latest power monitoring equipment on the market. That’s why the company is proud to announce the addition of the 5A Rope Kit with High Voltage Power Transformer – RōCoil TCA-5-HV-KIT to its product line which will allow users to take advantage of the broad current range and easy installation offered by the RoCoil Flex Probe CTs.
As a three-channel integrating transconductance amplifier (TCA), the RoCoil TCA-5 converts the 131mV/1000A electrical output signal from the RoCoil current sensor to a 5 amp AC current, thus emulating a traditional current sensing transformer. It is factory-calibrated to work with DENT RoCoil CTs (131mV/1000A).
Like any other device, current sensors and transformers must have at least one ground, namely in low-voltage circuits (below 1,000 volts). Although most systems are protected against sudden surges, it pays to add extra insurance to ensure the safety of the circuit, be it a solid-core, split-core, or Rogowski coil.
Grounding attaches a less-resistant conduit to the earth to provide as a return line for an excess charge, particularly one provided by lightning. Electricity follows the path of least resistance, so a ground connection can keep devices working and save lives. The earth is a poor conductor of electricity, after all, making it a suitable detour for excess voltage. Continue reading
Light Emitting Diodes, or LEDs, are the latest and best in the world of industrial lighting. An accelerating transition to these high energy-efficient devices has been changing the landscape of luminaries design on a global scale. In fact, LEDs are already prevalent in the products you buy and in the space you live, work, and play.
Despite their high efficiency, LEDs still need monitoring and current sensing devices to ensure they continue to function at an optimal level. Think about the LED lighting systems used in airports, tunnels, and industrial complexes. Think of the utter chaos and disorder that can occur if these systems fail. The measurement of current in these systems provides essential information so that users can take the necessary preventive or corrective steps appropriate for the situation. Continue reading
Industrial automation is a great way for businesses to cut down their operations costs. By allowing machines to complete menial tasks on their own, without supervision, and with a high degree of reliability, automation eliminates the various costs associated with retaining a worker to do the same thing—including labor, human resources, and damages for unintended errors.
