【英文介绍】

The stable differential relay SPAD 346 C is designed to protect double-winding power transformers and generator transformers. The main functions include winding short circuit, turn fault, ground fault and short circuit protection, as well as winding short circuit and extreme short circuit protection. In addition, relays can be used to protect three-winding power transformers, provided that 75% of the short-circuit power supply of the power transformer is supplied from the same direction.

The SPAD346C3 is a differential relay manufactured by ABB. A differential relay is a device used to protect the differential current in a power system. Differential current refers to the difference between the currents flowing through two current transformers and is usually used to detect faults in a line or device.
