The concept of overload power

Overload power refers to the situation where a device exceeds its rated power during actual operation. Every electrical device has a rated power, which is the maximum power that the device can withstand under normal operation. When the actual operating power of the device exceeds this rated power, it is called overload. The specific value of overload power depends on the type of device, the manufacturer, and the specific application scenario.

The impact of overloaded power

Running in overload condition can lead to various issues with electrical equipment. For instance, when an electric motor operates under overload, the temperature rise of its windings exceeds the allowed value, leading to insulation aging or damage of the windings. Additionally, overload can also cause short-circuit faults in the equipment, hence appropriate protective measures are necessary.

Overload Protection

To prevent damage to equipment due to overloading, overload protection devices are often employed. These protective devices can automatically cut off the power supply when an overload condition is detected, thereby preventing equipment damage caused by prolonged overloading. Common overload protection devices include thermal relays and overcurrent protection relays.

Conclusion

There is no unified standard for the specific value of overload power, as it depends on the specific equipment and application scenario. However, understanding the concept of overload power and its potential impact is crucial for ensuring the safety and reliability of electrical equipment. Appropriate overload protection measures should be considered when designing and using electrical equipment to prevent damage caused by overloading.
