Rogowski coils A Rogowski coil is used to make an open-ended and flexible sensor that easily wraps around the conductor to be measured. It consists of a helical coil of wire with the lead from one end ...

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 ...

The sensors also feature the RJ-45 style connectors used by these relays. LEA CURRENT SENSORS For switchgear applications, Lindsey offers both flexible Rogowski coil sensors and low-power CT options.

The 5-mm gauge RT sensors are currently available with sensing apertures measuring 55 mm or 125 mm in diameter. For further information, call LEM USA INC., Milwaukee, WI. (800) 236-5366.
