Primary harmonic eliminators are used to reduce the influence of ferroresonance on voltage transformers. By limiting resonance overvoltage and abnormal excitation current, they help protect voltage transformers and improve the safe operation of power distribution systems.

During the installation of power equipment, safety measures must be strictly followed, especially when laying power cables, working near live equipment, testing insulation resistance, and handling high voltage cabinets, transformers, low voltage cabinets, and cable systems.

An overcurrent protector is used to protect circuits and equipment when current exceeds a safe value. Under normal operating conditions, the protector should match the circuit requirements, fault current level, rated interrupting capacity, and equipment short-circuit current rating.

Portable electronic products such as mobile phones, PDAs, and notebook computers often require overcurrent protection in their switching power supplies. Proper overcurrent protection helps reduce equipment damage caused by unsuitable adapters, abnormal voltage, polarity mismatch, or excessive current.

The enclosure of a low voltage distribution cabinet refers to the outer shell of the cabinet. A reasonable cabinet enclosure structure can support internal component installation, ventilation, insulation, and production efficiency.

High and low voltage distribution cabinets are widely used in power distribution systems for circuit control and protection. Understanding common fault types such as malfunction, switching failure, insulation failure, current-carrying failure, and external damage can help improve troubleshooting efficiency and shorten maintenance time.

Temperature rise is an important factor affecting the safe and stable operation of high and low voltage switchgear. Reasonable design, online monitoring, regular maintenance, and improved heat dissipation can help reduce the probability of temperature rise failures.
