When reliable and fast indication of the failure section is needed after a short circuit, the fault detectors are a must-have. Fault circuit indicator is used to detect short circuit failures or phase-to-earth faults in electric power distribution networks. When it comes to an earth fault, an earth fault indicator is required. This device is projected to detect and report each incident in distribution networks of medium voltage. The abovementioned equipment reduces substantially the time and costs needed to find out the point of fault and eliminate the incident.

    Streamer Inc. had built the perfect customer trust. We design the indicators that undergo the three-stage quality control successfully. It means that our equipment will serve for at least 10 years without changing a battery.

    The installation of detectors was hardly ever so simple and ordinary. The further maintenance is even easier, because there is no need in that. These FCI will bother you only with its intended application, i.e. when a short-circuit happens.

    One more thing about the true beauty of our devices is that they have an anti-vandal construction. No idle barbarian could just throw a stone and break the equipment ― the latter is out of option.

    How does fault indicator work?

    1. The detector should be placed on key places on the line.
    2. In case an accident happens, it measures a short failure all along of the fault path.
    3. Each detector, located on that path, indicates the accident. It becomes easy to find the failure just keeping to the path.
    4. The device can communicate by sending the information with SMS/GPRS. It helps to determine the failure section.

    Main features of modern fault detecting devices

    • high indication visibility, which is possible due to high-brightness LED or xenon light sources;
    • failure information transmitting straight to the control station, using the GSM-connection and radio networks with data relaying;
    • good selectivity: it is possible to adjust the device response conditions depending on specific line preferences;
    • high accidental flowing sensitivity: the newest EFI detect earth faults with stream less than 1A.

    Pole mounted and conductor mounted FCI range

    When it is needed to fit out the line with FCI, pole mounted range is a cheap and easy solution.

    The conductors’ magnet field is checked by the detectors. The magnetic field imbalance is detected by the fault indicator during a phase to ground or a phase to phase of the short.

    In order to advance the equipment, the overhead line can provide the control point with the failure data, if the detectors’ range is installed in conductors.

    The devices check the current stream and the linevoltage. These values vary a lot during a phase to phase or phase to ground fault. The direction and the faulty phase are located by the fault passage indicator.
