Answer
Transformator (D) is in ster gekoppeld wat die transformator in staat stel om beide huis- en industriële laste te beperk. Dit help om die strome te balanseer en oorspanning te voorkom.

Answer
Transformator (B) is 'n verhoog transformator wat die spanning of die lyn verhoog, en sodanig die stroomvloei vermindert, wat die koperverliese verminder.

Answer
Hier is 'n grafiek wat 'n sinusgolf met benaming toon, wat die spanning oor tyd weergee, met amplitude en frequency wat ooreenstem met die opwekking by (A).
