Full wave bridge rectifier - Rectifier is a circuit which convert alternating voltage into the direct voltage. There are three types of rectifier circuit ‌ half wave rectifier ‌ full wave rectifier  ‌ full wave bridge rectifier  In this article we are going to discuss working principle and construction of full wave bridge  rectifier....

Why Tapping are provided on transformer winding? And what is benefit of Tapping Regulating voltage is required in power system due to following reason 1) to supply required voltage to load 2) to compensate voltage drops due to           load fluctuations 3) to compensate input voltage supply to load...

TESTING POWER TRANSFORMERS: High-voltage transformers are some of the most important (and expensive) pieces of equipment required for operating a power system. The purchase, preparation, assembly, operation and maintenance of transformers represent a large expense to the power  system.Why testing of transformer is necessary before putting in service? When...

IP Rated Enclosures ExplainedWhat is an IP rating?IP (or "Ingress Protection") ratings are defined in international standard EN 60529 (British BS EN 60529:1992, European IEC 60509:1989). They are used to define levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies (tools, dirt etc) and moisture.What do the numbers...
