Introduction; Applications - Megger Programma Sverker 750 User Manual

2.1 Applications

Sverker 750/760 is intended primarily for testing
relay protection equipment, but it can also be used
for many other purposes. Virtually all single-phase
relay protection equipment that does not require
variable frequency can be tested, and Sverker 750/
760 can also test three-phase relay protection
equipment that can be tested phase by phase.
Moreover, many relay protection systems that
require phase shifting can be tested.
Items that can be tested using Sverker 750/760
include:
Type of relay
Overcurrent relay
Inverse time overcurrent relay
Undercurrent relay
Ground fault relay
Directional overcurrent relay
Directional ground fault relay
Overvoltage relay
Undervoltage relay
