A Measurement represents any measured, calculated or non-measured non-calculated quantity. Any piece of equipment may contain Measurements, e.g. a substation may have temperature measurements and door open indications, a transformer may have oil temperature and tank pressure measurements, a bay may contain a number of power flow measurements and a Breaker may contain a switch status measurement. <br/>The PSR - Measurement association is intended to capture this use of Measurement and is included in the naming hierarchy based on EquipmentContainer. The naming hierarchy typically has Measurements as leafs, e.g. Substation-VoltageLevel-Bay-Switch-Measurement.<br/>Some Measurements represent quantities related to a particular sensor location in the network, e.g. a voltage transformer (PT) at a busbar or a current transformer (CT) at the bar between a breaker and an isolator. The sensing position is not captured in the PSR - Measurement association. Instead it is captured by the Measurement - Terminal association that is used to define the sensing location in the network topology. The location is defined by the connection of the Terminal to ConductingEquipment. <br/>Two possible paths exist:<br/>1) Measurement-Terminal- ConnectivityNode-Terminal-ConductingEquipment<br/>2) Measurement-Terminal-ConductingEquipment<br/>Alternative 2 is the only allowed use. <br/>When the sensor location is needed both Measurement-PSR and Measurement-Terminal are used. The Measurement-Terminal association is never used alone.<br/>

Notes:
|
Indicates to which phases the measurement applies and avoids the need to use 'measurementType' to also encode phase information (which would explode the types). Since Controls have associations with Measurements, they will have the capability to handle each phase. The phase information in Measurement, along with 'measurementType' and 'phaseConnection' uniquely defines a Measurement for a device, based on normal network phase. Their meaning will not change when the computed energizing phasing is changed due to jumpers or other reasons.<br/><br/>

Name: Terminal
One or more measurements may be associated with a terminal in the network.
|
Name: Measurement
Measurements associated with this terminal defining where the measurement is placed in the network topology. It may be used, for instance, to capture the sensor position, such as a voltage transformer (PT) at a busbar or a current transformer (CT) at the bar between a breaker and an isolator.
