Why the HT and LT voltage in the multiple of 11?

because our system form factor is 1.1


What is vector group YNd11?

we use Capital letters for the High Voltage ( Primary ) and we use small letters for Low voltage secondary so in this case: YN: it's refer to High Voltage, and it means the high voltage connection is Star and Neutral is Brought out. d: refer to Low Voltage and it means that low voltage connection is delta. 11: mean LV lead the HV by 30 degree. and others number it will be like bellow 01 02 03 04 05 06 07 08 09 10 11 12 30 60 90 120 150 180 210 240 270 300 330 360 or 0


What is the function of transformer 33kv?

A '33-kV transformer' is a three-phase primary-distribution transformer, used in the UK's electricity system to step down the 33-kV primary-distribution voltage to the 11-kV secondary-distribution voltage -the lowest voltage used in the high-voltage distribution system. These transformers are categorised as 'power transformers', and are located in what are termed 'primary substations'.


What is the difference between voltage forward voltage and voltage drop?

Voltage is the potential difference between the source & any point in the circuit. The forward voltage is the voltage drop across the diode if the voltage at the anode is more positive than the voltage at the cathode (if you connect + to the anode). Voltage drop means, amount of voltage by which voltage across load resistor is less then the source voltage.


What is voltage gain?

Voltage gain is the ratio of the output voltage of an amplifier to its input voltage.
