Regulator Data

A regulator is modeled as a two winding transformer in ePHASORSIM.

Regulator Data

Entry	Description	Acceptable values

Entry	Description	Acceptable values
Section ID	Regulator identifier	The section ID may not contain blank spaces.
Phase	Phase present in the network	At least one phase should be selected.
Primary (in ‘General’ sub-box of the ‘Settings’ box)	Primary side of the regulator	‘At From Node’ or ‘At To Node’
Nominal Rating (in ‘Nominal Data’ box of 'General' tab)	Rating power of the regulator in kVA	Any value
Rated Voltage (in ‘Nominal Data’ box of ‘General’ tab)	Rated line-to-line voltage in kV for both primary and secondary sides	Any value
Configuration (in ‘Configuration’ box)	Connection of the transformer	‘Star to ground’ or ‘delta’
Tap (in ‘Tap Settings’ box)	Tap position of the regulator	Any value

Note

Sequence impedances of the regulator, Z0 and Z1, are considered to be very small and they are both equal to 1e-8 ohms. Moreover X1/R1 and X0/R0 ratios are also assumed to be 10.
