As an electrical engineer or professional you already know that an electrical or distribution substation is very important components of any power distribution system. Normally electrical grid can be considered as simple circuit which includes power source or generation, power transmission and electricity distribution lines for connecting to the electricity consumers. The role of electrical… Read More »
In general understanding electrical distribution transformers are used to reduce primary system voltages (which is normally 2.4-34.5kV) to the level of utilization voltages i.e. 120- 600V. International electrotechnical commission standards do not distinguish between distribution electrical transformers and power transformer. They are all power electrical transformers in the sense that their purpose is to transmit… Read More »
Buchholz Relay Circuit is used for Transformer Protection, as we know there are many defects and dangers during the operation of power transformer that need to be addressed and necessary measures to be taken. Some of the hazards to transformer protection include overheating, over current and short circuiting etc. Another class of fault that causes a transformer… Read More »
