What is galvanic isolation？
Transformer Isolation：
Principle: Electrical isolation is achieved by utilizing the magnetic coupling between the primary winding and the secondary winding of the transformer. There is no direct electrical connection between the primary winding and the secondary winding of the transformer, but energy can be transferred through the magnetic field.
Application: It is widely used in power adapters, medical devices, laboratory instruments, etc.
Optocoupler Isolation：
Principle: Electrical isolation is realized by using an optocoupler (photoelectric coupler) to convert an electrical signal into an optical signal and then converting the optical signal back into an electrical signal. The optocoupler contains a light-emitting diode (LED) and a photosensitive element (such as a phototransistor) inside.、
Application: It is widely used in digital circuits, control systems, communication equipment, etc.
Relay Isolation：
Principle: Electrical isolation is achieved by using the contact switches of the relay. There is no direct electrical connection between the coil circuit and the contact circuit of the relay, but signals can be transmitted through the switching action of the contacts.
Application: It is widely used in control systems, switching circuits, etc.
Isolation Amplifier：
Principle: The input signal is isolated from the output signal by using an isolation amplifier while maintaining the amplification and transmission of the signal. The isolation amplifier usually contains isolation elements such as transformers or optocouplers inside.
Application: It is widely used in industrial measurement, sensor signal processing, etc.

Why Must a Transformer Core Be Grounded at Only One Point? Isn't Multi-Point Grounding More Reliable?Why Does the Transformer Core Need to Be Grounded?During operation, the transformer core, along with the metal structures, parts, and components that fix the core and windings, are all situated in a strong electric field. Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I01/29/2026 -
