The Circutor P5 Protection transformers from Eaton Electric Systems are part of the broad range of low voltage, measurement and protection heavy duty current transformers available from this company.
The Circutor P5 Protection transformers have been specifically manufactured in resin to increase the degree of strength (high mechanical resistance, high electrical rigidity, tropical weather
Current transformers are saturated when their current primary or load are above their rated values. The linearity of the current transformation between primary and secondary decreases and error increases. The difference between measurement or protection current transformers is their behaviour with the overload which occurs in the primary. Those transformers used for measurement are saturated when there is an overload in order not to damage the equipment in the secondary. Protection transformers are not saturated until there is a high current.
