BS EN 60255-11:2010 Measuring relays and protection equipment - Voltage dips, short interruptions, variations and ripple on auxiliary power supply port
This part of the IEC 60255 series specifies the general requirements for a.c. and d.c. power
supplies, for measuring relays and protection equipment for power system protection,
including the control, monitoring and process interface equipment used with those systems.
This part is based on:
• IEC 61000-4-11 for a.c. voltage dips, short interruptions and variations;
• IEC 61000-4-17 for voltage ripple;
• IEC 61000-4-29 for d.c. voltage dips, short interruptions and variations.
