What is the maximum allowable voltage difference for a balanced three-phase compressor?

The maximum allowable voltage difference for a balanced three-phase compressor is 2% of the average voltage measurements. This standard is essential for ensuring the efficient and safe operation of three-phase motors and compressors.

When the voltage balance is maintained within this 2% range, it helps to minimize issues such as overheating, excessive vibration, and reduced lifespan of the motor. A balanced voltage supply is crucial because any significant imbalance can lead to an increase in the current draw, which places stress on the electrical components and can result in failures or decreased performance.

Maintaining this maximum allowable voltage difference also ensures that the motor operates at optimal efficiency, which has implications for energy use and overall operational costs in commercial settings. Therefore, upholding this specification is vital for reliable and efficient refrigeration system operation.
