Current Sensors

FARADAY
SCG

This sensor would measure the leakage currents associated with the sheats of the power cables. The measure is derived from the current of a conventional current transformer, whose secondary is a coil which concentrates the magnetic field on a garnet which has a high Verdet constant.

SCF

This sensor measures the current using a conventional optical fiber. Therefore, it is completely linear and is not subject to saturations. As it is oriented to underground cables, the main measure would be short circuit of it.

SCM

It has two transformers on the outer envelope itself. On a same optical fiber it is possible to locate 6 sensors SCM, since each sensor has two current transformers.

CHARACTERISTICS

Current-sensors

La parte sensora, puede ser de dos tipos:

  • Fibra óptica. Existe campo suficiente para medir directamente desde la fibra óptica.
  • Materiales Garnet. Es posible concentrar el campo en un punto reducido, donde se ubica un elemento denominado Garnet, el cual posee una constante de Verdet muy elevada.
