On Monday, Japanese startup Helical Fusion announced that it has successfully completed a major performance test of its high-temperature superconducting (HTS) coil, a critical step toward developing ...

Japanese startup Helical Fusion advances to integrated demonstration phase after successfully testing a high-temperature superconducting coil under real fusion conditions.

Swiss sensor maker LEM has developed a novel non-contact current measuring technique based on a differential adaptation of the Rogowski principle. Rogowski coils Invented in 1912, Rogowski coils are ...

However, they produce an output voltage proportional to the derivative of the primary current they are sensing, and therefore need an electrical integrator to create a signal directly proportional to ...
