<p>PROBLEM TO BE SOLVED: To provide a current transformer secondary protective device wherein, being small, handling as well as service check-up is easy. SOLUTION: A non-linear resistor, an action display device 5 which is, provided above it, supported by a low-melting point solder, an insulating vessel 1 enclosing them, and a terminal 3 which is, provided on both ends of the non- linear resistor, conductive to outside of it are provided to a current transformer secondary protective device, wherein a zinc oxide element 14 is used for the non-linear resistor, as a feature.</p> |
