Abstract
Dispositivo de supervisión de continuidad de neutro y protección contra sobretensiones de servicio, que consta de un dispositivo electrónico (1) condicionador de las señales de tensión que se conecta a una red trifásica de baja tensión con neutro y mide las tensiones simples (V1), V2) V3) y la tensión homopolar asociada (VS), enviándolas a un elemento de control (2), programable, que por medio de un algoritmo realiza las funciones de activar una salida de alarma o de protección cuando detecta desequilibrios en las tensiones simples por averías en el conductor de neutro o en alguna de las fases, activar una salida de protección cuando detecta una sobretensión inadmisible en alguna de las fases y reconectar tras una avería después de comprobar las tensiones, siendo la protección un interruptor/contactor con mando eléctrico. De aplicación en la distribución de electricidad.Neutral continuity monitoring device and service overvoltage protection, consisting of an electronic device (1) conditioning the voltage signals that is connected to a three-phase low-voltage network with neutral and measures single voltages (V1), V2) V3) and the associated zero sequence voltage (VS), sending them to a programmable control element (2), which by means of an algorithm performs the functions of activating an alarm or protection output when it detects imbalances in simple voltages for faults in the neutral conductor or in any of the phases, activate a protection output when it detects an inadmissible overvoltage in any of the phases and reconnect after a fault after checking the voltages, the protection being a switch / contactor with electrical control . Applicable in electricity distribution.
