- Full scheme, 3+1 zone Impedance relay

|
|
|
|
|
This relay has 3 polygonal measuring zones. Each zone
can be separately directed forwards, reverse, bi-directional or blocked.
Zone 4 has independent settings in forwards and reverse directions. Two
independent voltage memory systems ensure correct directional
measurement. The relay also includes teleprotection,
switch-onto-fault-logic, power swing blocking, voltage transformer
supervision and phase unbalance supervision. |
The relay is very well suited as protection for
transmission and sub-transmission networks with isolated or solid
neutral grounding. The short manual and easy settings makes it
particularly useful when different types of personnel applies the unit |
