FAQ
Q1: What is ABB SPAU140C?
A: The SPAU140C is a numerical synchro-check relay manufactured by ABB in Finland. It monitors voltage magnitude, frequency, and phase angle between two power systems and permits circuit breaker closing only when all parameters fall within preset synchronization windows.

Q2: What is the difference between synchro-check and voltage-check functions?
A: Synchro-check verifies that both sides of a circuit breaker have matching voltage, frequency, and phase angle before allowing closure (used when connecting two live systems). Voltage-check only verifies that a disconnected bus/line has acceptable voltage before connecting it to an energized network section.

Q3: How many circuit breakers can SPAU140C monitor?
A: The SPAU140C has two identical operation stages, allowing it to simultaneously check the closing conditions of two separate circuit breakers. Each stage has independent synchro-check and voltage-check functions.
