Page 9: Section 1 • General Information
The BE1-60 Voltage Balance Relay provides a high-speed response to block other devices from incorrect operation resulting from a blown fuse or other fault in a potential transformer circuit. The BE1-60 detects these conditions, initiates corrective action, and indicates the problem and location. -

This condition would warrant an alarm indication and an orderly shutdown of the unit. The BE1-60 Circuit 1 output would accomplish this task and the Circuit 1 target would indicate that an open power potential transformer fuse had initiated the correct shutdown sequence. -

SECTION 2 • CONTROLS AND INDICATORS INTRODUCTION All BE1-60 controls and indicators are located on the relay front panel. The controls and indicators are shown in Figure 2-1 and described in Table 2-1. Figure 2-1. BE1-60 Controls and Indicators 9170700990 Rev D... - Page 16 Target indicators are manually reset by operating the target reset switch (locator D). Output Test Pushbutton The BE1-60 may be equipped with two pushbuttons (Circuit 1 (optional) and Circuit 2) that can be used to verify operation of the relay output contacts.

Page 17: Section 3 • Functional Description
STEP-DOWN TRANSFORMERS Voltage received from the power system potential transformers is applied to sensing transformers within the BE1-60 relay. The voltage is stepped down to appropriate levels and supplied to full-wave rectifier circuits within the relay. FULL-WAVE RECTIFIERS AND INTEGRATORS Outputs from the step-down transformers are full-wave rectified and then integrated. -

Circuit 1 output relay(s) and the upper pushbutton energizes the Circuit 2 output relay(s). AUXILIARY OUTPUTS Two sets of optional, auxiliary outputs are available on the BE1-60 relay. One auxiliary output changes state when the Circuit 1 output relay energizes; the other auxiliary output changes state when the Circuit 2 output relay energizes. -

Page 27: Maintenance
Figure 4-8. Typical Output Connections MAINTENANCE BE1-60 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 28 This page intentionally left blank.

Page 29: Section 5 • Testing
SECTION 5 • TESTING OPERATIONAL TEST PROCEDURE The following procedure verifies operation of the BE1-60 Voltage Balance Relay. Stated voltages refer to line-to-neutral for single-phase and wye inputs, and line-to-line for delta inputs. Terminal numbers may be found in Section 4, Installation. Target indicators, if present, should operate in conjunction with their corresponding output. - Page 30 This page intentionally left blank. BE1-60 Testing 9170700990 Rev D...
