AIM:
To draw the performance characteristics of 3-phase squirrel cage induction motor by conducting load test.
THEORY:
A 3-phase induction motor consists of stator and rotor with the other associated parts. In the stator, a 3-phase winding is provided. The windings of the three phase are displaced in space by 120º.A 3-phase current is fed to the 3-phase winding. These windings produce a resultant magnetic flux and it rotates in space like a solid magnetic poles being rotated magnetically.

HI GSM Green House Monitoring System (Model: WT-9001 IP65)




Appropriate environmental conditions are necessary for optimum plant growth, improved crop yields, and efficient use of water and other resources. Automating the data acquisition process of the soil conditions and various climatic parameters that govern plant growth allows information to be collected with WT-9001 with less labor requirements. The WT-9001 GSM Greenhouse monitoring systems employ PC or SMS-based systems for keeping the user continuously informed of the conditions ....etc

Aim
To conduct load test on three-phase squirrel cage induction motor.
Apparatus Required
Precaution
The motor should be started without any load.
Procedure
1) Connections are given as per the circuit diagram.
2) The TPSTS is closed and the motor is started using star-delta starter to run at rated speed.
3) At no load the speed, current, voltage and power are noted down.
4) By applying the load gradually with the help of spring balance and brake drum arrangements.
5) The speed, current, volta ....etc
