Current transformer (CT) saturation presents a critical challenge in the realm of power system protection and automation. Under fault conditions, the magnetic core of a CT may become saturated, ...

Solid-state ac supplies replace motor-generator and tap-changing transformers to offer the same tests at the push of a button • Solid-state ac-power sources combine the variable-frequency and ...

Testing speed, which significantly increases productivity and cuts costs, is a key benefit of Megger’s new compact MRCT current transformer (CT) test set. This unit also offers enhanced measuring ...

The EZCT-S2 from Vanguard Instruments is a second-generation, microprocessor-based, current transformer set. The EZCT-S2 will perform the current transformer saturation test and the CT (current ...

Achieves 1% accuracy for CTs up to 8000 amps, ensuring precise metering and billing with traceable, reliable results. By automating the testing process and integrating real-time data management, the ...

In power supplies, dc-dc converters and many other power electronics circuits, chokes and transformers form an essential part of the filter network that provides low-ripple dc power. In many designs, ...

Open-loop current sensors have a definite price advantage over closed-loop counterparts. While you can use them in drive applications where torque accuracy isn't demanding — such as pump and fan ...

We needed to detect motion in a commercial, stepper motor driven system and subsequently initiate motion in a servomotor based system we developed. Because both systems simulate human respiratory ...
