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

Regulator Data



Acceptable values

Section ID

Regulator identifier

The section ID may not contain blank spaces.


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.
