In this Video, Disha Mehtani, Asst. Prof., Biyani Group of Colleges explains about the construction and working of Buchholz Relay. This relay is a gas operated relay and is used for the proctection of oil immersed transformer. Basically a relay is used for the protection against power system when there is a fault in the system.

In this Video, Disha Mehtani, Biyani Group of Colleges explains about the UPS. Basically ac power supplies can be used for ups I.e standby power supply for critical loads. It has two configuration: 1. load is directly supplied from main source. 2. the load is supllied from an inverter.

Hand writing Analysis is all about how you craft your words indicates 5000 different personality traits and this science is known as “Graphology”. Your personality can be easily judged just looking at the way you write so go through this interesting lecture to judge yourself.

This lecture is presented by Ms. Apoorva Gupta, Asst. Professor of Biyani International Institute of Engineering and Technology. HVDC transmission system is used to transmit bulk power over a long distance without much loss of power and with great efficiency. There are three types of dc links for HVDC transmission system.

This lecture is presented by Ms. Apoorva Gupta, Asst. Professor of Biyani International Institute of Engineering And Technology. Speed control of electrical drives are the control system used for controlling the speed of the electrical drives which can be any motor or generator etc..Control of the electrical devices is very important for the proper working of the derive system and there are basically five blocks in the control system.

This lecture is presented by Ms. Apoorva Gupta, Asst. Professor of Biyani International Institute of Engineering and Technology. Base load plants supply the electric power constantly through the 24 hours of the day while the peak load plant supply the electric power only during the peak hours of the day and they generally supply the load for 4 to 8 hours of the day which is generally from 10 am in the morning to 4 pm in the evening.

This lecture is presented by Ms. Apoorva Gupta, Asst. Professor of Biyani International Institute of Engineering and Technology. Motor is basically that device which convert electrical power into mechanical power .There are five types of motor first, separately excited motor .second self excited motor which is further subdivided into two types series excited motor and shunt excited motor third one is compound excited motor it is sub divided into long shunt compound excited motor and short shunt compound excited motor.

This lecture is presented by Ms. Apoorva Gupta, Asst. Professor of Biyani International Institute of Engineering And Technology. Hydro Power Plant uses kinetic energy of water to generate electricity, it is generally used as peak load power plant and its working time is generally of 4 to 8 hrs. These power plants are of reversible type means they work as generator when supplying the load and as motor during the night time duration or off peak hours.

This lecture is presented by Ms. Apoorva Gupta, Asst. Professor of Biyani International Institute of Engineering And Technology. Types of D.C. Link this lecture explain in detail the types of d. c. links which are mono polar, bipolar and homo polar .These types of dc links help to transmit bulk amount of electric power through the HVDC Transmission line.

This lecture is presented by Ms. Apoorva Gupta, Asst. Professor of Biyani International Institute of Engineering And Technology. Power Modulator are those devices which are used to convert the given electrical power into the desired power for e.g. the supplied power is of ac form than and required is dc than we will employ rectifier power modulator for converting ac power into dc , and if the given form is dc and required is ac than we will employ a inverter power modulator.
