The BTB200 controller provides the ability to control a bus tie-breaker, for applications where it is necessary to divide the common bus-bars during certain operating conditions.
It manages the synchronization between the two separated halves of the bus-bars (named A and B), based on an input signal, taking into account the number of generator sets connected on the two halves.
Generator sets synchronisation is achieved directly by the CANBUS connection to the SICES genset controllers, or alternatively by using analogue lines.
BTB200 measures the current flow across the tiebreaker (3ph) by means of current transformers. It is able to measure the active (kW), reactive (kvar) and apparent power (kVA) exchanged on the bus-bars (and the power factor too), showing the flowing direction (A to B or B to A) on the display and by the LEDs on the front panel.
BTB200 also measures the total energy on the bus-bars using energy counters (active and reactive, A to B and B to A).
