microBEL Sx
A range of controllers for MV switchgear
-
They combine the functions of a short-circuit indicator and a telemechanics unit
-
They enable remote diagnostics of the uninterruptible power supply
-
They support local change-over switches I-0-II and signals
Find out what the microBEL SX has to offer
microBEL SX controllers are designed to operate MV transformer substations and cable terminations equipped with current transformers and voltage sensors that enable the measurement of phase currents and voltages in several MV bays. Based on these measurements, the controller performs earth fault and phase-to-phase fault detection functions (for disconnector bays) or protection functions (for circuit breaker bays) in networks with any type of neutral point configuration.
Maintenance of transformer stations and MV cable joints

Detection of earth faults and phase-to-phase faults in switchgear bays
Implementation of safety functions for switchgear panels
Operation in networks with any type of neutral point earthing
Independent operation of functions for each MV panel
