Basler BE1-25 Instruction Manual

The BE1-25 Sync-Check Relay monitors the voltages on both sides of a circuit
breaker and determines that proper phase angle and voltage exist prior to closing the
circuit breaker.
Phase angle limit is adjustable over the range of 1 to 99 degrees.
•
Time delay is adjustable over a range of 1 to 99 cycles or 0.1 to 99 seconds.
•
Voltage monitoring circuits provide independent determination of bus and line
•
voltage levels for selectable closing conditions.
Voltage difference provides additional verification of proper breaker closing
•
conditions.
Expandable phase window option provides the capability to quickly close critical
•
system ties under emergency conditions.
Separate sync and voltage monitor output contacts are available.
•
Optional external selection of voltage conditions.
•
Qualified to the requirements of
•
- IEEE C37.90-1978, C37.90a-1974, and IEC 255 for surge withstand
capability;
- IEEE C37.90.1-198Xfor fast transient;
- IEC 255-5 for impulse.
UL Recognized under Standard 508, UL File #E97033.
•
Five year warranty.
