Voltage sensor setting example
The voltage sensor is based on the resistive divider or capacitive divider
principle. Therefore, the voltage is linear throughout the whole measuring
range. The output signal is a voltage, directly proportional to the primary
voltage. For the voltage sensor all parameters are readable directly from its
rating plate and conversions are not needed.
In this example the system phase-to-phase voltage rating is 10 kV. Thus,
the
sensor measurement support the
sensor" and it cannot be changed. The same applies for the
parameter which is always set to "WYE" type. The division ratio for ABB
voltage sensors is most often 10000:1. Thus, the
usually set to "10000". The primary voltage is proportionally divided by this
division ratio.

Binary input filter time

The filter time eliminates debounces and short disturbances on a binary input. The
filter time is set for each binary input of the protection relay.
