F2 27-59
: Second voltage element 2U
It operates same as the first element the programmable parameter are :
- Pick-up level :
2u
= (5-50)%Un, step 1%
- Independent trip time delay :
t2u
= (0.1-60)s, step 0.1s
- Operation mode : (Un
+/-
2u)
2.3.12 - F81 : Dual level over/under frequency
F1 81
: First frequency element 1f
- Pick-up (operation) level of frequency difference :
1f
= (0.05-9.99)Hz, step 0.01Hz
- Independent trip time delay :
t1f
= (0.1-60)s, step 0.1s
- Operation mode : (Fn
+/-
1f)
The function can be programmed to operate as :
- Overfrequency (Fn
+
1f) : operates when the frequency rises above the rated value [Fn] by
more than 1f Hz.
f
(Fn+[1f])Hz
- Underfrequency (Fn -
1f) : operates when the frequency drops below the rated value [Fn] by
more than [1f]Hz.
f
(Fn-[1f])Hz
- Frequency balance (Fn
+/-
1f) : operates when frequency differs from rated value by more
than [1f]Hz.
f
(Fn+[1f])Hz or f
(Fn-[1f])Hz
- Operation blocked : (Fn = Dis)
F2 F81
: Second frequency element 2f
It operates same as the first element ; the programmable parameters are :
- Pick-up level :
2f
= (0.05-9.99)Hz, step 0.01Hz
- Independent trip time delay :
t2f
= (0.1-60)s, step 0.1s
- Operation mode : (Fn
+/-
2f)
