The rated CT currents applied to the SIPROTEC 7SJ600 can be 1 or 5 A. The relay is a non-directional overcurrent re- lay which can be used for line protection of high and medium-voltage networks with earthed (grounded), low-resistance earthed, isolated or compensated neutral point. Motor protection When protecting motors, the 7SJ61 relay is suitable for asynchronous machines of all sizes. Transformer protection The SIPROTEC 4 7SJ63 unit is a numerical protection relay that also performs control and monitoring functions and therefore sup- ports the user in cost-effective power system management, and ensures reliable supply of electric power to the customers.

The corresponding device driver for 7SJ66 V4.3 has also been installed in the Laptop. However, when trying communication of new 7SJ66 relay with laptop through the relay's front USB port and an straight male-male USB cable, the laptop is not detecting the relay. The SIPROTEC 7SJ64 can be used as a protective control and monitoring relay for distribution feeders and transmission lines of any voltage in networks that are earthed (grounded), low-resistance earthed, unearthed, or of a compensated neutral point structure.
