Analog Inputs
These inputs can be configured by the User to represent the status of external analog values that are fed to the relay.
Using Analog Inputs is a two step procedure. The user has to configure the
Measuring Elements and the Analog
Protection Elements. Each Analog Input (hardware) is represented by one Measuring Element (named AnIn[x]). That
means the number of
Measuring Elements is equal to the number of analog inputs. The user can set for each
Measuring Element the type of input (e.g. 4...20 mA). The Measuring Element will provide, based on this setting, analog
values. The values that are provided by the
Measuring Elements have to be assigned onto the Analog Protection
Elements in order to feed them. Hence one Measuring Element can be assigned on multiple Analog Protection
Elemtents. The number and names of the Analog Protection Elements are depending on the ordered device.
Examples for
Analog Input Elements.
Generator Protection Device (Example): FldC[n] - DC Field Current.
Motor Protection Device (Example): Spd[n] – Speed.
Transformer Protection Device (Example) TapV[n] - Tap Voltage.
Each
Analog Input Element is available as an Alarm and as a Trip Element.
The Configuration comprises:
Step 1 (please see section “Setting the Measuring Elements”): The first step is to set within the [Device Parameters] the
type of input for each available Analog Input (Measuring Element). That means determining, what kind of measuring
values will be provided by each analog input (e.g. 4...20 mA).
Step 2 (please see section “Configuring the Analog Protection Elements”): Configuring an Analog Protection Element
means: Activating the "Trip and/or Alarm-Element" within the [Device Planning]. After that, the Element has to be
configured within the [Protection Parameters].
