Current Sensing Benefits for LED Systems

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

The Hall Effect: Electricity and Magnetism

Current sensors appear nothing more than a square piece with a hole in the center. Yet this design allows them to take accurate current and voltage measurements for direct current (DC) systems. This is one of the most notable applications of the Hall Effect, a phenomenon that affects charged carriers like wires. Continue reading

A Quick Guide to Selecting a Current Transformer

When you’re planning to install an ammeter in an existing electrical circuit that transmits high voltage electricity, you will need to also install a current transformer. This is a device that reduces the voltage of the electricity flowing through the system to protect the measuring device and the person installing it from electrocution. However, choosing a current transformer suitable for the circuit is not that simple. Continue reading

Current Transformer—Measuring without Touching

A typical transformer consists of two coils of insulated wire wound around an iron-containing core. One coil is connected to the source of electricity, while the other to the device being powered with the transformed electricity. The ratio of the number of turns the coils are wound to the core depends on how much transformation is needed. Continue reading
