An unwanted electrical current that disrupts the normal operation of electronic devices or systems, often caused by external electromagnetic fields or improper grounding.
高压线产生的干扰电流可能损坏敏感的电子设备。
Interference current from high-voltage power lines can damage sensitive electronic equipment.
屏蔽电缆可以有效减少干扰电流对信号传输的影响。
Shielded cables can effectively reduce the impact of interference current on signal transmission.
In power systems, interference current often refers to harmonic currents or ground fault currents that deviate from the standard operating frequency.
Interference current typically refers to unwanted currents from external sources (e.g., power lines), while noise current often originates from within the system (e.g., thermal noise in resistors). Use '干扰电流' for external disruptions and '噪声电流' for internal system noise.
Proper grounding is the primary method to mitigate interference current. Ensure all equipment shares a common ground reference to prevent potential differences that can induce unwanted currents.
The term combines '干扰' (gān rǎo, meaning 'interference' or 'disturbance') and '电流' (diàn liú, meaning 'electric current'). It entered technical Chinese vocabulary in the mid-20th century as electrical engineering developed, directly translating the English concept of 'interference current'.
In Chinese technical contexts, '干扰电流' is the standard term for unwanted currents that disrupt system performance. It is distinct from '信号电流' (signal current) and '噪声电流' (noise current), though overlaps exist in practice. Always specify the context (e.g., electromagnetic interference, grounding issues) when discussing mitigation strategies.
