Hey guys do you know about the frequency to verify the GE UR Relays in order to make sure that its active functions are working properly since it was commissioned and stays online. Someone said normally should be every year but I don't know if any standard covers this matter. Any coments from you i will appreciate..

Find out what your Regional Reliability Organization will allow.  I believe that in the WECC if you fully monitor the relays alarm contact you can go nine years.
