1. Adopt high-efficiency and energy-saving motors, such as Y2, Y2E and YX series motors.

2. The motor that starts frequently adopts soft starter.

3. The fan and water pump motor are controlled by frequency converter.

4. Take local reactive power compensation measures.

5. Reduce the power supply voltage appropriately, for example, if the power supply voltage is 400 volts, adjust it to 380 volts. ..

But whether it is necessary to adopt energy-saving transformation does not meet the requirements of energy-saving transformation. Generally, a power quality analyzer, such as Guangzhou Zhiyuan Electronics E6000, is used to test the active power, reactive power and apparent power of the motor under no-load condition, and then it is substituted into the specific calculation formula to calculate whether the motor needs energy saving. See GBT 12497-2006 for details.
