Measurement functions
6.12 Electrical network parameters
The sentinel Energy trip unit requires configuration of the parameters associated with the
characteristics of the electrical network. The parameters of nominal voltage Un, nominal
power Pn, nominal frequency Fn, and the sign convention of power polarity are used by the
measurement functions of the sentinel Energy trip unit. These parameters have no eect on
the protections except the reverse active power protection.
These parameters are accessible from the CONFIGURATION NETWORK of the sentinel
Energy display, the panel display or the Hager Power setup software.
Nominal voltage setting
This setting allows the nominal voltage of the electrical network to be configured.
Network Un V 208 to 690 V
Nominal power setting
This setting allows the nominal power of the electrical network to be configured.
Network Pn kW 50 to 9995 kW in increments of 5
Nominal frequency setting
This setting allows the nominal frequency of the electrical network to be configured.
Network Fn Hz 50 or 60 Hz
Setting the power sign convention
The power sign convention parameter is used to configure the power sign according to the
supply direction of the Energy circuit breaker.
Configuring this convention correctly enables the 4 quadrant set-up to be respected:
- Positive active power when the downstream equipment operates as a receiver,
- Reactive power, on the one hand with the same sign as active power when the equipment downstream
is inductive, on the other hand with the opposite sign when the equipment downstream is capacitive.
P sign convention Default setting
Positive - negative Positive
P < 0 P > 0
Q > 0 II Capacitive (lead) I Inductive (lag)
Q < 0 III Inductive (lag) IV Capacitive (lead)
