Rural network challenges | Catalogue Rural network challenges Since typically 80 percent of a rural network’s faults are transient, 80 percent of its fuses are blown unnecessarily. In most rural network configurations, the feeder is protected by a circuit breaker or recloser. Lateral ines l (also referred to as T-offs or spur lines) are usually protected by fuses. As a fuse is unable to distinguish between temporary and permanent faults, it blows on all faults, causing downstream customers to lose power and requiring a line crew to replace the fuse. In rural networks, it may take hours for the...

Fusesaver™ is the most cost-effective solution for optimising reliability while minimising operating costs of rural overhead medium-voltage networks. It is capable of almost completely removing the impacts of temporary faults on lateral lines. Fusesaver™ is a new class of intelligent, compact and low-cost, single-phase reclosing circuit-breaker. With on board microprocessor control and wireless connectivity, Fusesaver™ has configurable protection, multi-phase operation functions, on board event history, load profiling and can be integrated into a SCADA system for remote control. It is an electrically...

Fusesaver™ | The Fusesaver™ system, self-powering, magnetic actuator, nameplate The Fusesaver™ system In order to minimise installation and operating costs, the Fusesaver™ was developed as part of an integrated system of tools and accessories. All system components work together, which permits easy installation, fast commissioning, and reliable operation in all conditions. A typical Fusesaver™ installation includes the following items for each phase: 4. Communications Module. Configuration of the unit is achieved through a wireless connection to a PC application called Siemens Connect. Design...

Vacuum interrupter, position indicator, external lever | Fusesaver™ Vacuum interrupter The Fusesaver™ relies upon Siemens well-established vacuum interrupter technology. The vacuum interrupter utilised in the Fusesaver™ is a specific innovation by Siemens to facilitate the half-cycle fault interruption capability required to be able to save fuses successfully. Position indicator The indicator is directly coupled to the magnetic actuator and has red/green colours to indicate close/open status (colours can be reversed by special order). Fusesaver™ position indicator External lever The Fusesaver™...

Fusesaver™ | Line mounting, crossarm, pole, or line-tension mounting, Communications Module Fusesaver™ mounting options Fusesaver™ is an electrically floating device so requires no grounding. This product architecture allows for a number of different mounting options. In all cases the Fusesaver™ has been designed to be mounted horizontally. Line mounting The preferred method for mounting of the Fusesaver™ is to hang it directly from the line using the line-clamp assembly. The line-clamp assembly connects directly to the dead-end of the conductor and ensures that the Fusesaver™ is hung at its...

Wireless communications, battery, LED and fault-passage indication, tripping and closing, attachment tool | Communications Module Wireless communications The Communications Module includes an intelligent, short-range wireless transceiver, which enables encrypted communication using the public 2.4 GHz band. Battery The Communications Module includes a battery to provide power to run the Communications Module radio and to manually operate the Fusesaver™ when the line current is off. The Communications Module is available in two models: 1. The classic version with fitted-for-life, primary-cell bat...

Siemens Connect | Software configuration and operation Siemens Connect software Communication with the Fusesaver™ circuit breaker is performed using a PC application called Siemens Connect and a USB radio antenna. With these items, a local operator has short-range (approximately 20 m) access to the Fusesaver™ over the encrypted radio link. Fusesaver™ plus Communications Module communicates with USB antenna Configuration The Fusesavers™ are configured wirelessly through the S iemens Connect PC application. All the user needs to do is to identify the Fusesavers™ to be configured together as a site,...

Event data, load-profile data, reliability data | Siemens Connect Event data Fusesaver™ stores a time-stamped history of the major events in its on-board memory. The event record contains a history of up to 3,000 events including protection operations, fault data, outage durations, and configuration changes. The event data can be viewed using the Siemens Connect PC application. Data can be filtered and exported as required. Load-profile data The Fusesaver™ can collect data on the current flowing in ach phase of an installation. The Fusesaver™ can e report the following data for each 24 hour period:...

Fusesaver™ | Protection settings Fusesaver™ protection Fusesaver™ with partner fuse – time-current curve (a FAST protection curve can be added as shown in the lower figure) Time-current curve Fault detection is achieved with a cutting-edge, highspeed protection algorithm that is capable of detecting faults within 2 ms. On the first trip, the Fusesaver™ can clear the fault in the first half-cycle after contact part when required. The default Fusesaver™ protection algorithm uses an inverse protection curve that is based upon an i2t value. b K-type 15 A fuse d Fusesaver™ set to coordinate with a...
