why measure the gravity in battery?
What is mechanical interlock?Explain the uses?
If oil and air can withstand a high MeV when used as an insulator in a transformer, what are the values of how high for each material?
what is the transmission loss for electrical supply? specifically a large shopping complex where the grid is half KM away, what will the % of transmission loss? is there any transmission loss for captive unit generation for above set? thanks

Why PT is fitted in incomer panel.....?
We have ONLINE UPS 15KvA (3PHASE 440V I/P,3PHASE O/P,440V) I want to step down from 440 to 220 V What to do. Pl. suggest with specification.
how many types of grounding?
assume we are put both df/dt and vector surge relay in same bus the df/dt relay setting is +5 hz an -5HZ. we want operat the vector surge relay before the df/dt how i calculate the setting of the vector surge relay.
kVA rating of ordinary transformer is increased when connected as an auto transformer because A transformation ratio increased B secondary voltage increased C energy is transferred both inductively and conductively D secondary current increased
