Modelica.Electrical.Analog.Sensors

Information

This package contains potential, voltage, and current sensors. The sensors can be used to convert voltages or currents into real signal values o be connected to components of the Blocks package. The sensors are designed in such a way that they do not influence the electrical behavior.

Package Content

Name	Description
PotentialSensor	Sensor to measure the potential
VoltageSensor	Sensor to measure the voltage between two pins
CurrentSensor	Sensor to measure the current in a branch
PowerSensor	Sensor to measure the power

Modelica.Electrical.Analog.Sensors.PotentialSensor

Information

The potential sensor converts the voltage of a node (with respect to the ground node) into a real valued signal. It does not influence the current sum at the node which voltage is measured, therefore, the electrical behavior is not influenced by the sensor.

Connectors

Name	Description
p	pin to be measured
phi	Absolute voltage potential as output signal [V]

Modelica.Electrical.Analog.Sensors.VoltageSensor

Information

The voltage sensor converts the voltage between the two connectors into a real valued signal. It does not influence the current sum at the nodes in between the voltage is measured, therefore, the electrical behavior is not influenced by the sensor.

Connectors

Name	Description
p	positive pin
n	negative pin
v	Voltage between pin p and n (= p.v - n.v) as output signal [V]

Modelica.Electrical.Analog.Sensors.CurrentSensor

Information

The current sensor converts the current flowing between the two connectors into a real valued signal. The two connectors are in the sensor connected like a short cut. The sensor has to be placed within an electrical connection in series. It does not influence the current sum at the connected nodes. Therefore, the electrical behavior is not influenced by the sensor.

Connectors

Name	Description
p	positive pin
n	negative pin
i	Current in the branch from p to n as output signal [A]

Modelica.Electrical.Analog.Sensors.PowerSensor

Information

This power sensor measures instantaneous electrical power of a singlephase system and has a separated voltage and current path. The pins of the voltage path are pv and nv, the pins of the current path are pc and nc. The internal resistance of the current path is zero, the internal resistance of the voltage path is infinite.

Connectors

Name	Description
pc	Positive pin, current path
nc	Negative pin, current path
pv	Positive pin, voltage path
nv	Negative pin, voltage path
power	Instantaneous power as output signal [W]
