Transformer rating is in kVA not in kwThe manufacturer of transformers fixed a name plate on the transformer on which are recorded the rated output, the ratedvoltages, the rated frequency etc. of a particular transformer.A typical name plate rating of a single phase transformer is as follows : 20 kVA, 3300/220 V, 50Hz. Here 20 kVA is the rated output...

explanation about protection provided to induction and other types motor are given below:In order to avoid unexpected breakdowns, costly repairs and subsequent losses due to motor downtime, it is important that the motor is fitted with some sort of protective device. Generally speaking,Motor protection can be divided into the following 3 levels:• External...

DIFFERENT TYPE OF DC LINKS:How many types of dc links? Direct-current links are classified as followsMono polar dc linkBipolar dc linkHomo polar dc link 1) Mono polar dc link: The monopolar link has one conductor usually of negative polarity, and ground or sea return.
