Bibliography

Defines minimum requirements for over/under current relays. It includes a specification of the protection function, measurement characteristics and time delay characteristics.

IEC 60255-151:2009 specifies minimum requirements for over/under current relays. It includes a specification of the protection function, measurement characteristics and time delay characteristics. Defines the influencing factors that affect the accuracy under steady state conditions and performance characteristics during dynamic conditions.
