Differential Protection is used to protect the Generators & Transformers from internal faults.Differential Protection Relays are used to do so.Before the energisation of power transformer,it must be ensure that the connections doen for differential protection are in order.

Wrong connections/C.T. polarity may cause mal-function of Differential Protection Relays

Differential Stability Analyzer can simulate different abnormal conditions of differential circuits of a Yy0 group power transformer

Global warming refers to an average increase in the Earth's temperature, which in turn causes changes in climate. A warmer Earth may lead to changes in rainfall patterns, a rise in sea level, and a wide range of impacts on plants, wildlife, and humans. When scientists talk about the issue of climate change, their concern is about global warming caused by human activities.

Earth has warmed by about 1ºF over the past 100 years. But why? And how? Well, scientists are not exactly sure. The Earth could be getting warmer on its own, but many of the world's leading climate scientists think that things people do are helping to make the Earth warmer.
