Isolation transformers usually have good anti-interference performance, but not all isolation transformers can completely resist interference. The following are some considerations for the interference immunity of isolation transformers:
1. Magnetic coupling and isolation: Isolation transformers provide electrical isolation through magnetic coupling rather than direct electrical connection. This isolation design prevents high-frequency interference signals from being transmitted through the electrical connection, reducing the impact of noise and interference.
2. Insulation and winding design: The insulation design of an isolation transformer usually takes a series of electrical isolation measures, such as the use of insulating materials, appropriate insulation layer thickness and insulation structure design. These designs provide better insulation and reduce the transmission of electrical noise and interference.
Although the isolation transformer has good anti-interference ability, there are still some factors that may affect its interference resistance:
1. Frequency range: Isolation transformers are often designed to optimize performance over a specific frequency range. Interfering signals outside a specific frequency range may have a greater impact on it.
2. Environmental interference: The environment around the isolation transformer may contain electromagnetic interference sources, such as electromagnetic field interference, high-frequency noise and radio frequency band interference sources. These interference sources may affect the performance of the isolation transformer through airborne transmission or through conduction and radiation.
3. Design quality and characteristics: The design and manufacturing quality of an isolation transformer will directly affect its interference resistance. Poor quality design and manufacturing can lead to leakage, poor insulation, or structural problems in electrical connections, affecting its performance.
