Improvement on the reliability of protection function
Any parts and materials applied to the protection relay have limited lifetime which will bring the degradation to
the relay. The degree of degradation will be variable depending on the purpose, aging,
usage environment, and
unevenness on the performance of each part.
Our company designs its products so that the recommended renewal period is 15 years or more.
However, there may be some possibilities to occur any failures before reaching 15 years due to above reasons.
To prevent unwanted operation or no operation of relay, it is recommended to apply the relay with self-diagnosis
function and/or multiplexing relay system such as dual or duplex scheme.
