    (Figure 1-1c). Phase Fault Detection BE1-50 relays can be used in two ways to detect phase faults. The first method is to place an instantaneous overcurrent element in each phase with the setting higher than expected load current for any power system element (Figure 1-1a, d, e, f).

  • Page 10: Combination With Other Protective Devices

    BE1-50 electrical characteristics and operational features are defined by a combination of letters and numbers that make up the style number. Model number BE1-50 designates the relay as a Basler Electric Instantaneous Overcurrent Relay. The model number, together with the style number, describes the options included in a specific device and appears on the front panel, draw-out cradle, and inside the case assembly.

BE1-50 relay functions are illustrated in Figure 3-1 and described in the following paragraphs. Figure 3-1. Function Block Diagram...

  • Page 18: Pickup Settings

    The optional power supply status relay has a set of normally closed contacts and energizes when operating power is applied to the BE1-50. If relay operating power is lost or one side of the power supply output (+12 Vdc or –12 Vdc) fails, the power supply status relay de-energizes and opens the power supply status output contacts.

  • Page 19: Current Operated Targets

    Current operated targets are triggered by closure of the output contacts and the presence of at least 200 milliamperes of current flowing in the trip circuit. NOTE Prior to September 2007, BE1-50 target indicators consisted of magnetically latched, disc indicators. These mechanically latched target indicators have been replaced by the electronically latched LED targets in use today.

    Figure 4-19. Typical Internal Connections, Single-Phase, Output E MAINTENANCE BE1-50 relays require no preventative maintenance other than a periodic operational check. If the relay fails to function properly, contact Technical Sales Support at Basler Electric to coordinate repairs. STORAGE This protective relay contains aluminum electrolytic capacitors which generally have a life expectancy in excess of 10 years at storage temperatures less than 40°C (104°F).

  • Page 39: Section 5 • Testing

    (option 3-6), verify that these contacts when external power is applied. Remove input power and verify that the status contacts close. (For relay styles with power supply types F, G, and H, the relay is powered from the current sensing inputs.) Figure 5-1. Test Circuit Connection 9171000990 Rev E BE1-50 Testing...
