structure_type_id

The type of structure that is causing an interference in the sensor's measurements.

structure_type_id

structure_type_id Type

string (Structure Type)

structure_type_id Constraints

enum: the value of this property must be equal to one of the following values:

Value Explanation
"lightning_finial"
"aviation_light"
"guy_wires"
"other"

orientation_from_mast_centre_deg

The orientation of the interference structure, relative to the centre of the mast, causing an impact on the sensor's measurements.

orientation_from_mast_centre_deg

orientation_from_mast_centre_deg Type

number (Orientation from Mast Centre [deg])

orientation_from_mast_centre_deg Constraints

maximum: the value of this number must smaller than or equal to: 360

minimum: the value of this number must greater than or equal to: 0

orientation_reference_id

The orientation reference the item is measured against. E.g. magnetic north.

orientation_reference_id

orientation_reference_id Type

string (Orientation Reference)

orientation_reference_id Constraints

enum: the value of this property must be equal to one of the following values:

Value Explanation
"magnetic_north"
"true_north"
"grid_north"
null

distance_from_mast_centre_mm

The distance from the mast centre to the interference structure causing an impact on the sensor's measurements.

distance_from_mast_centre_mm

distance_from_mast_centre_mm Type

number (Distance from Mast Centre [mm])

distance_from_mast_centre_mm Examples

900

diameter_of_interference_structure_mm

The diameter of the Interference Structure. If lightning finial, then it can be used for IEC validation. For irregularly shaped structures, a representative diameter would be sufficient for an analyst to understand it's size.

diameter_of_interference_structure_mm

diameter_of_interference_structure_mm Type

number (Diameter of Interference Structure [mm])

diameter_of_interference_structure_mm Examples

30

date_from

The date from when these properties are active. If these properties follow a change, then this Date From should equal the previous Date To. The format of this date should follow ISO 8601 with the 'T' required. If a timezone is used, it is essential that this timezone is the same as the logger timezone.

date_from

date_from Type

string (Date From)

date_from Constraints

date time: the string must be a date time string, according to RFC 3339, section 5.6

date_from Examples

"2020-07-28T20:00:00"

date_to

The final end date for when these properties are active. If these properties are currently active please use null. If null is not allowed please use 2100-01-01T00:00:00. The format of this date should follow ISO 8601 with the 'T' required. If a timezone is used, it is essential that this timezone is the same as the logger timezone.
