This can be defined in the load-flow page of the transformer. The attached example shows how to use a phase-shift transformer to control the active power shared between several transformers…
To change the tap position of a 3-winding transformer during a simulation define a parameter event (EvtParam) using the appropriate variable: e:nntap_int_h which corresponds to the tap-position HV…
Several EMT studies (transformer energisation, load rejection, ferro-resonance etc.) require a detailed model of the non-linear behaviour of the transformer iron core which is defined by its…
The loading on an element such as a transformer or line is always based on the current.For a transformer, the loading for each side is calculated from the actual current and the rated current for that…
These are the different Apparent Power variables which can be selected in the flexible data page of a transformer or line. Using the transformer as an example: m:Smax:bushv (Maximum power)…
There are various possibilities to ground the star point of transformers. Generally, the grounding is defined on the Basic Data page => Grounding / Neutral Conductor. The following options are…
The attached example project shows three different possibilities to implement automatic voltage regulators (AVR), installed along a line. The most left arrangement uses an auto transformer, where the…
