Residential Lighting (Illumination) : A residential lighting system is not same as a commercial lighting system. From design and product selection to installation, there are several factors that distinguish the two types of lighting systems. When planning the lighting design, it is necessary to understand the difference to avoid the wrong application and an inefficient … Read more
Three Phase Transformer Generally, electrical energy is generated in generating stations by 3-phase alternators. 3-phase system is used for transmission and distribution of Electric-energy. For stepping down or stepping up the voltage of these systems, 3-phase transformers are used. Advantages of 3-Phase Transformer over 1-Phase Transformer (For Same Capacity) Q. State the advantages of three … Read more

Let us first of all know the suitable lamps/luminaries for residential purpose and illumination levels required for different parts of the residential area. (A) Light Sources for Room Lighting / Residential Lighting : … Read more
Industrial Applications of Transformer Q. Give industrial application of transformer. Transformer is such a important device used everywhere, where voltage from one value is to be changed to the other value. In generating stations to increase the voltage for transmission lines. In receiving stations, sub-stations to step down the voltage. In street light distribution. In … Read more
Primary of Transformer is connected to D.C. supply Q. What will happen if the Primary of the Transformer is connected to D.C. of the same Magnitude? A d.c. current will not produce the alternating flux and hence there will not be any self induced E.M.F. to oppose the supply voltage. Moreover the winding resistance is … Read more
UPS full form :- Uninterruptible Power Supply UPS PARTS NAME AND FUNCTION. Rectifier The rectifier carries out several key functions. The first is to convert the input power from AC (Alternating Current) to DC (Direct Current). Its second main role is to recharge the batteries, while the DC power routes to the inverter too. Depending … Read more
Pulse Transformer For coupling square wave or a pulse from primary to secondary the conventional transformer need change of shape of signal. Pulse transformer is a transformer which is designed to couple pulses from primary to the load connected to secondary without changing the shape of the pulse. Pulse transformers are used for coupling pulses … Read more

High Frequency Transformers In this category we study (1) Audio frequency (AF) transformer (2) Intermediate frequency (IF) transformer. (1) Audio Frequency (AF) Transformer Audio frequency range is 20 Hz to 20 kHz These transformers are especially designed for connecting different telephone systems to each other keeping their respective power supplies ‘isolated’. Following are the functions … Read more
