The frequency of testing solid state (static ) protection relays
The frequency of testing solid state (static ) protection relays
(OP)
Is there any standard, either IEEE or IEC,which recommends a particular frequency for periodic testing of static protection relays. As per Du pont standard, the frequency is 6 years for microprocessor based (numerical relays). Is it applicable for static relay as well. Does a relay manufacturer recommends it ?
