Overhead Automatic Transfer with Overcurrent Protection Case Study Solution G&W Viper-S ® reclosers with SEL 351-R controls (Lazer ® Automation Solution) makes an ideal solution for overhead automatic source transfer applications also requiring load side overcurrent protection. Typically, the reclosers and controls are positioned at the junction point for the preferred (or normal) source and at the alternate (or standby) source for the critical load(s). If desired, however, the SEL controls can be linked via Mirror Bit communication using radio or fiber optic cable, permitting the reclosers to be installed at any point on the source circuits. Challenge The vast majority of electrical service interruptions are on overhead circuits. Exposure to the elements, wildlife, and tree
