One of the main requirements for electrical isolation protection is that the isolated equipment or circuitry must be powered by a separate power source. This power supply can be an isolation transformer or a power supply with a safety rating equivalent to an isolation transformer. Electrical isolation is generally achieved with an isolation transformer with a voltage ratio of 1:1.
2 All sockets in the circuit must have dedicated jacks for equipotential bonding.
3 Except for flexible cables that supply Class II equipment, all flexible cables must contain a protective core for equipotential bonding;
4 Set the protection device that automatically cuts off the power supply. It is used to automatically cut off the power supply of the fault circuit according to the specified time when the two devices in the isolation circuit have different phase line faults.
