Horstmann Faulted Circuit Indicators

Dipl. Ing. H. Horstmann GmbH is a medium-sized company based in Heiligenhaus near Düsseldorf (Germany). The company was founded in 1946 by Heinrich Horstmann, and since that time it has been a successful family-owned company. Due to its long experience and continuous investment in research and product development Horstmann is today recognized as a leading manufacturer in medium voltage technology for:

  • Short-circuit and earth fault indicators
  • Voltage testers and voltage detecting systems
  • Earthing devices and accessories.

Horstmann offers a wide variety of Horstmann FCIs designed for North American underground distribution circuits and overhead distribution and transmission lines.

This includes specialty products and solutions providing remote fault indication and circuit information for today’s SMART networks.

Our products meet highest quality requirements and are developed and manufactured in own production facilities in Germany. In order to respond to these demands, we have a very high vertical depth of production (e. g. own SMD assembly system) as well as an own research and development department with state-of-the-art testing and measuring equipment. Besides the electronics manufacturing, we have also a mechanical production facility for safety material.

Our company has been certified according to DIN EN ISO 9001 since 1996.

Rexel Utility is the preferred distributor of Horstmann GmbH Representatives across Canada and offer a wide variety of Horstmann FCIs designed for the North American high and medium voltage market.  Horstmann meets the needs of the underground and  overhead transmission, sub transmission and distribution lines.  This includes specialty products providing remote fault indication and circuit information for today’s integrated SMART networks from 120 volt to 161 kV applications

Featured Horstmann Faulted Circuit Indicators:

Smart Navigator 2.0

The Smart Navigator 2.0 continuously monitors the over-head line and provides measured values and fault information to the control room.  This enables engineers (or automated alorithms) to initiate immediate switching and circuit restoration decisions.

The indicator is a self-powered sensor which harvests its power supply from the overhead line.  Power is stored in a rechargeable lithium cell for period with low or no load current.  Each unit is simply and securely clipped onto a phase conductor of the overhead line.  A set of three units at each monitored location consists of one master and two satellite units.  The master communicates via cellular networks directly to SCADA without the need for a pole-mounted box.

Smart Navigator 2.0

Smart Navigator 2.0 HV

The proven overcurrent detection algorithm detects fault currents reliably under a wide range of network situations.  Individual parameter settings tailor the Smart Navigator 2.0 HV perfectly for all locations in your overhead line network, eliminating false tripping.

Fault messages containing information about fault direction, voltage interruption, current drop and increase in conductor temperature support the problem detection and root cause identification. Every fault is signaled to the control room within 1 minute.

iHost

iHost manages data and communication between smart FCIs and SCADA.

iHost provides a single platform for utilities to manage the increasing number of low cost, communicating, “smart field devices” installed throughout the power network.

Installing iHost enables the utility to make best use of these new devices whilst at the same time extending the information horizon of existing SCADA and other IT systems.

Smart Reporter

Horstmann’s Smart Reporter solution allows utilities to receive event based fault and circuit load information directly to their SCADA systems via DNP3 protocol. A multi-output Smart Receiver located in the Smart Reporter enclosure communicates with up to 12 Smart Navigators individually and provides all their data to a SCADA system via connection to an installed customer specified modem/router. The engineered Smart Reporter solution includes a wide range AC power supply, battery backup, heater, tamper protection and IP66 lockable enclosure. A Power Management Unit (PMU) is available to ensure long life to the backup battery and data transmission.

Integrating into existing SCADA communications systems (wired or wireless) creates a self-contained data acquisition solution, the Smart Reporter provides the critical information required by today’ utilities to make valued decisions.

Navigator LM

Navigator LM Overhead Faulted Circuit Indicator ≤ 46kV

Navigator is the latest generation of faulted circuit indicators, utilizing over 60 years of experience from the Horstmann Company.

Designed for overhead distribution circuits, the Navigator LM fault indicator quickly and accurately aids trouble crews in determining the status of the system and the location of faults. Installed on bare or covered conductor the unique design allows for easy installation and/or removal with a hot stick.  The speed at which a crew can find the Fault is greatly increased, saving time and money.

Navigator LM Overhead Faulted Circuit Indicator ≤ 161kV

Navigator LM Overhead Faulted Circuit Indicators for voltages ≤ 161kv are available from the Horstmann Company.

Identical in features to the original ≤ 46kV Navigator LM, attached to the housing is a conductive wire cage to shield the internal electronic circuits of the Navigator from the high intensity electrostatic field surrounding transmission lines up to 161kV.

Easily installed on conductor for viewing from the ground or from a patrolling helicopter the unique design provides all around visibility.

FCI – LT – LM Series Underground PPZ Sensing Sequence

Load Tracking – Load Memory
c/w Pulse/Pause/Zero

FCI – LT Series Fault Indicators are primarily designed for utility underground cables, where phase to phase spacing is limited. The closed core, cable clamping mechanism is designed to significantly reduce the proximity effect of adjacent cables and for easy installation and/or removal with a hot stick.

Various bail sizes are obtainable to meet the needs of small and large cable size.

In combination with the Underground FCI’s, Fiber Optic cables are supplied to remotely view the FCI flash from outside the metal clad gear.
