HIGH ATTENUATION ISOLATION TRANSFORMERS
WITH OVERVOLTAGE PROTECTION
IREM Isolation Transformers of the RS series are characterized by:
high attenuation of common mode disturbances, achieved thanks to a ground-connected electrostatic shield inserted between the windings;
attenuation of overvoltages caused by lightning and line commutations. This is obtained by connecting 3 varistors between phases and ground. Each surge arrester is fitted with a device signaling when the varistor is out of order.
