Instruments and protective devices
Measuring and protecting your transformer.

CEDASPE manufactures several instruments and protective devices to ensure that both power and distribution transformers can work in safe conditions. Instruments are mainly used to check and control most sensible transformer elements and components; protective devices spring into action when faults occur in order to protect the transformer and avoid the risk of damage propagation.
