The BE1-87T Transformer Differential Relay is designed as primary protection for power transformers against internal faults. Available in either single- or three-phase configurations, this solid-state relay compares the currents entering and leaving the protected transformer. If any imbalance is detected that is not attributable to other (tested) factors, the relay provides a contact closure to isolate the power transformer to limit damage.FEATURES• Single- and three-phase configurations. • Input isolation. • Three-phase configuration includes internal phase shift compensation with zero-sequence current blocking. • 2nd- and 5th-harmonic restraint. • Adjustable through-current restraint. • % IOP display. • Tap scaling covers the range of 2.0 to 8.9 amperes in 0.1-ampere increments in 5 Ampere CT models, and 0.4 to 1.78 amperes in 0.02 ampere increments in 1 Ampere CT models. • Low sensing burden. • Maintains proper operation when tested for interference in accordance with IECC C37.90-1989, Trial-Use Standard Withstand Capability of Relay systems to Radiated electromagnetic Interference from Transceivers. • UL listed (except for 250Vdc power supply). • Five year warranty
