1.Zero voltage regulation in a transformer occurs at :
(A)zero p.f. lead 
(B)unity p.f.
(C )leading p.f.
(D)lagging p.f.

2.A parallel plate capacitor has 15 p.F capacitance. If the linear dimensions of the plate are doubled and the distance between the plates are also doubled, then new value of capacitance would be :
(A)15uF
(B)30 uF
(C )60 uF
(D)7.5 u.F

3.Resistance of a 230 V 100 W bulb is R1 and that of a 230 V 75 W is R2. Then,
(A)R1= R2
(B)R1 > R2
(C )R1 < R2
(D)R1 - 2R2

Definition

Instrumentation and controls in a boiler plant encompass an enormous range of equipment from simple industrial plant to the complex in the large utility station.

The boiler control system is the means by which the balance of energy & mass into and out of the boiler are achieved. Inputs are fuel, combustion air, atomizing air or steam &feed water. Of these, fuel is the major energy input. Combustion air is the major mass input, outputs are steam, flue gas, blowdown, radiation & soot blowing.

ABSTRACT
Instrumentation and controls in a boiler plant encompass an enormous range of equipment from simple in the small industrial plant to the complex in the large utility station. Boiler Instrumentation Control is the control over the industrial boilers. It consists of several control loops to control various systems related to a boiler. The main control of boilers include combination control and feedwater control. To do the various operations in control different hardware methods are used. ....etc

Components
The system comprises a Transmitter, converter module, float chamber, a feedline modulating control valve and an electronic microprocessor based PID/FUZZY controller.

Operation
A positive change of water level in the boiler alters the level transmitter inductance value of coil causing an imbalance in the system. This signal is transmitted through the electronic control box and connected to PID controller. Then the microprocessor-based PID level controller transmitted an electr ....etc

ABSTRACT



Because of high requirements in power, efficiency, installation space and weight, the design of electrical machines for hybrid electrical vehicles is a particular challenge. This seminar describes a comparative study allowing the selection of the most appropriate electric-propulsion system for a parallel hybrid electric vehicle (HEV). This seminar is based on an exhaustive review of the state of the art and on an effective comparison of the performances of the four main electric propulsion systems, namely the d ....etc

DESIGN OF BOILER STACK
ABSTRACT
Chimney, which form the last component of a system using a flue gas such as feoiler, IC engines, play a vital role in maintaining efficiency, draft, etc, of a system and also in minimizing the atmospheric pollution.
The boiler plant of HOCL had used LSHS (low Sulphur heavy stock) as a fuel. Recently they changed the fuel to LSFO (low Sulphur furnace oil). As a combined effect of increased corrosion rate and natural calamities the stack had undergone failure. As per the Kerala State Polluti ....etc
