The power industry has many professional terms, which are difficult for beginners, non-technical users and project managers in Southeast Asia to understand. This article selects the most commonly used 10 professional terms, explains them in popular language, without complicated principles, and helps you quickly master the basic vocabulary of the power industry.
All terms are closely related to transformers, power distribution and electrical safety, which are practical and applicable to daily work and communication. The specific explanation is as follows:
| Professional Term | Popular Explanation | Application Scenario |
|---|---|---|
| Transformer | A device that converts high voltage into low voltage (or vice versa) to meet the power demand of different equipment | Industrial production, residential power supply, rural electrification |
| Insulation Resistance | The ability of electrical equipment to block current leakage, the higher the value, the safer | Transformer inspection, cable maintenance, electrical safety test |
| Surge Arrester | A “protector” that diverts thunderstorm surges and voltage spikes to the ground, protecting equipment from damage | Outdoor transformers, distribution boxes, thunderstorm-prone areas |
| Load | The total power of all electrical equipment connected to the power system, equivalent to “the amount of electricity used” | Industrial power distribution, transformer selection, load balance |
| Grounding | Connect electrical equipment to the ground to discharge leakage current and avoid electric shock | All electrical equipment, especially outdoor and high-voltage equipment |
| Oil-Immersed Transformer | A transformer that uses transformer oil for heat dissipation and insulation, durable and suitable for outdoor use | Outdoor power supply, industrial projects, rural areas |
| Short Circuit | The positive and negative poles of the circuit are directly connected, causing excessive current and equipment damage | Electrical fault handling, daily inspection |
| Distribution Box | A “switchboard” that distributes power to different equipment, controls and protects the circuit | Factories, residential buildings, construction sites |
| Desiccant Breather | A device that absorbs moisture in the air to prevent moisture from entering the transformer and damaging insulation | Oil-immersed transformers, humid areas |
| Overload | The load exceeds the rated capacity of the equipment, which is equivalent to “overloading” the electrical equipment | Transformer operation, power distribution safety |
