## STUDY OF SERIES INVERTER USING SCR

Experiment No.: 2 Experiment Name: To Study Series Inverter using SCR Objective: To study the mechanism of working of inverter using SCR. Theory: In series inverter, the commutating elements L and C are connected in series with the load. This constitutes a series RLC resonant circuit. The Two SCRs are used to produce the halves (positive and …

## Testing the Performance of Given UPS

Experiment No.: 4 Experiment Name: Test the performance of given UPS Objective: To test the performance of given UPS Theory: An uninterruptible power supply or uninterruptible power source (UPS) is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails. A UPS differs from an auxiliary or emergency power system or standby generator in that it …

## Determination of negative temperature coefficient and calibration of a Thermister

Experiment No.: 5 Experiment Name: Determination of negative temperature coefficient and calibration of a Thermister Objective: To determine negetive temperature coefficient and calibrate a Thermistor Theory: Thermistor (10 K): Thermistor is a contraction of a term thermal resistor. Although positive temperature co-efficient (P.T.C) of unit exhibit an increase in the value of resistance with increase …

## Temperature measurement using Thermocouple.

Experiment No.: 4 Experiment Name: Temperature measurement using Thermocouple. Objective: To measure temperature by using thermocouple Theory: Thermocouple (J/K type): The Thermocouple is the most commonly used type of all the temperature sensing devices due to its simplicity, ease of use and their speed of response to changes in temperature, due mainly to their small …

## Calibration of given LVDT

Experiment No.: 3 Experiment Name: Calibration of given LVDT Objective: To measure Linear displacement by LVDT To plot displacement v/s output voltage characteristics curve Theory: The most widely used inductive transducer to translate the linear motion into electrical signal is the Linear Variable Differential Transducer (LVDT). The basic construction of LVDT is given in the …

## Speed Measurement by using Stroboscope

Experiment No.: 2 Experiment Name: Speed Measurement by using Stroboscope Objective: To measure speed by usinh Stroboscope Theory: The primary use for a stroboscope is to stop motion for diagnostic inspection purposes. However, the stroboscope can be used to measure speed. In order to do this, several factors need to be considered. First, the object …

## Measurement of Strain by using Basic Strain Gauge and Determine the Stress Induced.

Experiment No.: 1 Experiment Name: Measurement of strain by using a basic strain gauge and hence determine the stress induced. Objective: To measure strain by using a basic strain gauge To determine the stress induced Theory: It is a resistive transducer as well as passive transducer and it works on the basis of familier equation …
