g.) For a step up three phase distribution transofmer the preferred connection is ________
h.) Which secondary connection of a three phase transformer is used to suplly three different voltage loads simulatenously? _____________
i.) Which type of regulation can be used to control power? ____________
j.) What types of power stations is used to supply the base load in a utility company? Name two:
k.) In which side a tap changer is located in a transofmer connected Delta/Star?
L.) What technology is used to extract electricity from hot water?
m.) Which of the two distribution transofmers gets its supply by a cable?
Explanation / Answer
1) for a residential area underground residential layout is recommended. although a specific fault on an underground circuit might take longer to locate and repair, underground systems fail less often and the average customer outage time (averaged over all customers) is less for most underground systems.
2) Due to saturation in power transfoemrs, the current has a high percentage of fifth harmonic.
3)For a step up three phase distribution transofmer the preferred connection is delta- star connection. This is because this delta-star connection is most economical.
4) the technology that is used to extract electricity from hot water is thermoelectric tubes.
5) the tap changer is located in the star side of the transformer
