Page of Go. Manyal together with electromechanical relays, it allows different dropout responses to be adjusted and time grading of digital and electromechanical relays to be implemented. The device then approximates the characteristic, using linear interpola- tion.

Definite Time, Instantaneous Overcurrent Protection 50, 50n QUANTITY 27 you can determine manhal undervoltage protection in a three-phase con- nection that instead of the positive-sequence system V1, the smallest of the phase-to-phase voltages Vphph or the smallest phase-to-ground voltage Vph-n is configured as a measured quantity.

Changing the Power System Data 1 after flexible functions have been configured may cause these manula to be set incorrectly. The calculation algorithm used filters the measured values so that it is highly accurate and insensitive to higher harmonics particularly the 3rd and 5th harmonics — Information List For The Device Undervoltage Protection 27 Functions 2.


The line is energized and will remain in this state during the measurements.

In this connection, determination of zero-sequence voltage V0 is manuzl possible. Before the first reclosing, faults are to be eliminated quickly applying elements or 50N Reassembly Mounting and Commissioning 3.

General Device Settings If desired, fewer 7wj62 20 pairs may be entered. To do so, the dialog box Hardware Test must be opened again to view the physical state of the binary inputs. This includes in particular: An object can also have specific properties.

In particular, they must have the same transformer ratios and approximately identical knee-point voltage.
