Open three-phase non short circuit proof transformer with power range up to 30 kVA. Designed and tested according to EN61558-2-4. Standard types supplied with separate primary and secondary windings. This generates ”a new system” in which any earth faults are eliminated. Degree of protection IP00. Applications: This is an ideal design for transforming voltage up or down or for installations which require a galvanic partition between the primary and sec-ondary voltage. Protects installations and equipment by generating ”a new system” in which any earth faults are eliminated. E.g. electric motor,...
