Star delta is a method of starting three-phase motors with reduced voltage.

• It involves connecting the motor windings in a star configuration during starting and then switching to a delta configuration once the motor is up to speed.

• This reduces the starting current and torque, which can be useful for large motors or when the power supply is limited.

• For example, a 30 kW motor might draw 60 amps at full voltage, but only 35 amps when started in star delta mode.

• The switch between...read more

• Preventive maintenance helps in identifying and addressing potential issues before they escalate into major problems.

• Regular maintenance schedules can prevent unexpected breakdowns and costly repairs.

• Proper maintenance can also improve the efficiency and productivity of plant and machinery.

• Examples: Regularly checking and replacing worn-out parts, lubricating...read more

The grade of grease for an excavator machine depends on the operating temperature and load capacity.

• The most common grades of grease used for excavator machines are NLGI 1 and NLGI 2.

• NLGI 1 is suitable for low-temperature applications and light loads.

• NLGI 2 is suitable for high-temperature applications and heavy loads.

• It is important to consult the manufacturer's recommendations for the specific excavator model.

• Regular maintenance and lubrication of the machine is crucial for...read more

A capacitor is an electronic component that stores and releases electrical energy.

• A capacitor consists of two conductive plates separated by an insulating material called a dielectric.

• When a voltage is applied across the plates, one plate accumulates positive charge while the other accumulates negative charge.

• Capacitors are commonly used in electronic circuits to store energy, filter out noise, and stabilize voltage levels.

• They can be found in various devices such as power su...read more
