Abstract:
A ground fault isolation system (100) and ground fault isolation circuit for isolating ground faults in electrical subsea conductor lines. The system includes a main power hub, a plurality of digital controllers operatively connected to the main power hub via electrical subsea conductor lines, and a ground fault isolation circuit (100). The ground fault isolation circuit includes a plurality of loads connected to a ground fault detection circuit (12), each load including one relay (22) on the positive power bus (18) and one relay (26) on the negative power bus (20). The ground fault detection circuit is connected to a DC to DC isolation circuit (10) that prevents a main power bus ground fault in the event of a ground fault on one of the loads. The relays are connected to a digital controller (16) on the other end, which isolates a load when a ground fault is detected, but powers the remaining unaffected loads.
Abstract:
Ein Verfahren zum Trennen von fehlerhaften Netzabschnitten eines Niederspannungsnetzes von weiteren Netzabschnitten des Niederspannungsnetzes ist dadurch gekennzeichnet, dass mehrere Netzabschnitte jeweils durch einen Leistungsschalter (5, 6) voneinander getrennt sind, wobei benachbarte Leistungsschalter (5, 6) miteinander zur Bestimmung einer Leitungsdifferenz in drahtloser Datenverbindung (8) stehen und den zwischen ihnen liegenden Netzabschnitt vom Niederspannungsnetz trennen, wenn ein vorgegebener, einem Fehler entsprechender Differenzwert der Ströme, die durch benachbarte Leistungsschalter (5, 6) fließen, überschritten wird. Damit kann ein großflächiger Ausfall der Spannungsversorgung im Fehlerfall reduziert werden.
Abstract:
The object of the invention is a multipurpose smart module (A,B) for detecting the operating status of electric devices (D) that enables monitoring the status of functioning devices (D) through installation. The module (A,B) of the invention is designed on data collection (voltage drop, current size, temperature, moisture, etc.) on an installation protection means (C) and allows detecting a change (disconnection or other changes) and identification where or on which protection means (C) a change has occurred (disconnection or other changes); the module further allows monitoring of operation of a monitored device (D) that can wirelessly communicate with a monitoring unit (E), and receiving energy through electromagnetic waves from monitoring unit (E), wherein the module (B) not only collects the data (voltage drop, current size, temperature, etc.) and indirectly measures power, it can be wirelessly remotely switched on or off.
Abstract:
A power distribution system for regulating energy transfer from a source includes a source controller responsive to a source sensor that provides feedback including a signal indicative of the voltage across the source terminals; a source disconnect device responsive to a control signal from the source controller for electrically connecting or disconnecting the source from the source terminals, wherein the source controller interrupts the supply of power by opening the source disconnect device when voltage is measured across the source terminals; a load disconnect device for electrically decoupling the load from the load terminals; and a logic device in the source controller for determining whether the source disconnect device is to be opened to interrupt the electrical connection between the source and source terminals based on a predetermined set of conditions including whether the change in voltage across the source terminals in respect to time falls outside a predetermined range.
