A variable frequency drive vfd is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor.
Single phase submersible starter connection diagram. In on state gives low voltage at output and in non conducting state gives high voltage at its output all transistors outputs are connected to 12345678 pins portb of microcontroller. For star delta staterthe motor connection must have 6 cables from control panel and 6 terminals at induction motor u1u2v1v2w1w3to wiring the motor connection for star delta starterthe important thing that we must fully understand is about the basic of star delta magic triangle. What is a vfd.
Marketers concerned about fueling times efficiency serviceability reliability and overall quality find it an easy choice to specify fe petro brand submersible turbine pumps stps. The use of transistor is it acts as inverter ie. Based upon equipment rating.
At a pressure of 1000 v applied between each live conductor and earth for a period of one minute the insulation resistance of hv installations shall be at least 1 mega ohm or as specified by the bureau of indian standards. Eg g controls e section 16695 pump control systems. Variable frequency drive in short vfd is an energy saving device by converting fixed frequency to adjustable frequency to control ac induction motor in variable speed base on the loads changes also know as variable speed drive frequency inverter and adjustable frequency drivesvfd also works as a phase converter to convert single phase input to three phase output in small ratings.
In effect there are four states. For detail about star delta stater please read my last. As per ie rules 1956.
Frequency or hertz is directly related to the motors speed rpms. 1 hp fixed speed submersible turbine pumps. The star contactor serves to initially short the secondary terminal of the motor u2 v2 w2 for the start sequence during the initial run of the motor from standstill.
