## Lecture on Transformer Regulation

Subject: Engineering | Topics: ,

Primary purpose of this lecture is to presentation on Transformer Regulation. Regulations of a transformer means the difference between the full-load and no-load supplementary terminal voltages expressed as a percentage of the full-load voltage. Here also discuss on efficiency of a transformer, it is a power factor means the output divided by the input- the two being measured from the same unit. This lecture also explain Condition for Maximum Efficiency, Uses of Auto-Transformer, Additive Polarity and Subtracting Polarity. Finally discuss on Parallel Operation of Single-Phase Transformer and Three Phase Transformer with mathematical examples and graph.

### Generator Differential Protection System

Over view of Differential Relay: While over-current, voltage, distance and directionality are powerful techniques, all of them involve some compromise between the objectives of reliability, security, speed, selectivity and economy. Differential protection is different. It is profoundly simple, in.....
