Transformers can be deployed with a variety of protection options, including a MagneX interrupter or a secondary breaker with weak link for secondary fault and overload protection; a primary weak link fuse; a current-limiting fuse for high interrupting ratings and limiting fault currents; a low-voltage, distribution class MOV arrester; and internal or external lightning arresters. These protection options eliminate the need to install external overcurrent devices and simplify power restoration.
