Abstract :
Protection system is a tool that can be interpreted as a protection or
protection of a device that functions to detect interference or abnormal
automatically. 3 phase induction motor is the most widely used motor in the field
of industry, so the 3 phase motor is considered very important in the industrial
world, so the induction motor must work properly and safely while operating.
There are so many disturbances that occur in the 3 phase induction motor in it,
namely overload, unbulance voltage and increase in temperature on the 3 phase
induction motor. The protection system of the 3 phase induction motor is
automatically controlled by Arduino Uno. The overload limit, unbulance voltage
and temperature rise will be adjusted according to the ability to operate a 3 phase
induction motor, this protection system uses the Arduino Uno microcontroller.
From the results of testing the Analysis And Design Tool for the 3 Phase
Induction Motor Protection System as Prime Mover. The difference in
measurement results of the ZMPT101B voltage sensor and power supply is 4.3%
error, the current sensor readings displayed on the ACS712 power supply and
current sensors have an error of 5.2% and the DS18B20 temperature sensor
measurement and an error measuring 5.15%. Comparison of real values and
sensor measurement values are still included in the normal category.
