3 Page 1 round-fault Indication System Rev FEATURES reen ED s indicate presence of voltage to ground for each phase of a power system. o A ground fault (or phase loss) is indicated when a set of ED s is off. o ED s are on when phase-to-ground voltage exceeds 30 Vac. o Redundant ED s are used for reliability. Pressing causes all ED s to light. Note: The feature requires an isolated ac supply. Direct connection for voltages up to 600 Vac line to line. o Potential transformers (PT s) are required for voltages greater than 600 Vac. Provides faulted-phase indication for resistancegrounded systems and ungrounded systems. 2. DESCRIPTION The is a self-powered ground-fault indication system. Presence of phase-to-ground voltage is indicated by redundant ED s (two per phase). The respective phase ED s are off when phase-to-ground voltage is less than 30 Vac. The meets the National Electrical Code requirements for ground detectors for ungrounded alternating-current systems as defined in NEC It also meets the Canadian Electrical Code requirements for ungrounded alternating-current systems in accordance with CEC (2). 3. INSTAATION Outline and panel-mounting details are shown in Fig. 1. For 208- to 600-Vac systems, connect the directly to the three-phase bus. For 208- or 240-volt installations, use terminals A, B, and C. For systems above 240 V and up to 600 V use terminals AH, BH, and CH. See Figs. 2, 3 and 5. For systems above 600 V, install PT s as shown in Figs. 4 and 6. Connect terminal and chassis-bonding terminal ( ) to ground. For connect ac supply to terminals and.
