Does anyone have any comments on the idea of putting load on the tertiary winding of an autotransformer - in this case a 400/132kV earthed Star autotransformer with a 33kV delta tertiary winding?
It is not uncommon in the UK to have reactive compensation connected to such tertiaries but this...
Hi all,
Does anyone know of any manufacturer of MV (33kV) shunt tapped reactors that offers a range down to 0 MVARs (or close). Designs based on a single core apparently limit the devices due to volts/turn limits so the ranges can't be say 0-8 MVAR but only say 4-8 MVAr (4MVAr shunt on minimum...
The machine reactances used for calculating fault currents in Industrial systems are usually the saturated reactances. The UK standard (ER G74) states (para 9.1.3) that unsaturated machine reactances should be used for fault current calculations for EHV faults (i.e. on the 400 kV Transmission...
