star delta starter control circuit
Its ok to start small motor directly… but there is one big problem when you will start big motor
Directly.
A large induction motor in delta can produce an sudden or inrush current of over 5 times its
full load capacity when starting up!
The surge or simply sudden increase in current can cause a lot of problems as the electrical system will be hit with a massive demand at once. This can lead to component failure and fires due to the temperatures rising in the infrastructure. Voltage drops can also appear on other machines/devices across the electrical network which is a problem for things such as computers and servers.
What is solution for that problem..?
We use star delta starters to reduce the current when a motor starts.
By using star delta starters we reduce the starting voltage which causes a drop in the starting current.
