735/737 Feeder Protection System Protection The 735/737 is a digital feeder relay designed for primary circuit protection on distribution networks of any voltage. Advanced protection features include: Three-Phase and Ground TOC Distribution Feeder Protection The 735/737 provides a choice of five separate TOC curve shapes. For each curve shape 10 different time multipliers and four different curve shifts may be set. Three different curve types can be selected: ANSI, IAC, and IEC/BS142. This allows the selection of the optimum curve for coordination with equipment. The front dials allow the...
