kVA is the total power in a circuit, while KVAR is the reactive power in a circuit.

• kVA is the apparent power in a circuit, which is the combination of real power (kW) and reactive power (KVAR).

• KVAR is the reactive power in a circuit, which is the power that oscillates between the load and the source without being consumed.

• kVA is used to size the electrical equipment, while KVAR is used to correct the power factor of th...read more

Nitrogen gas is used in suspension cylinder to prevent foaming and cavitation.

• Nitrogen gas is used as a cushion to prevent the formation of air bubbles in the hydraulic fluid.

• It also prevents cavitation, which can cause damage to the cylinder and reduce its efficiency.

• Nitrogen gas is non-reactive and does not corrode the cylinder, making it a suitable choice for suspension systems.

• Examples of suspension systems that us...read more
