- A compact and reliable hand-held tool to make LV fuse replacement safe and avoid personal injury.
- The Kelman Fusemate closes the faulted circuit and displays the current flowing.
- The operator is a safe distance away using remote control.
- Fusemate has a fuse in series with a miniature vacuum switch. Its control and monitoring electronics
   provide the indication and control functions.

How FUSEMATE Works :

- Use of Fusemate gives the operator crucial information to enable him to deal with the circuit safely.
- When closed under ‘Normal load’ current conditions the Fusemate will complete the circuit and display
   the current level on the LED bar graph display.
- When closed under ‘Fault’ current conditions, the fuse in the Fusemate blows to provide automatic protection
   for the operator (for abnormal currents where the fuse has not blown, the operator can open Fusemate).
- The trigger mechanism in the Fusemate is designed to give a uniformly controlled opening operation which is
   independent of the operator action and can safely interrupt up to 2kA.

The Fusemate is designed to carry a maximum load current for a short period of time in order to allow a
circuit to be tested (typically less than 5 minutes) and should normally be removed from the circuit as soon as the
current level has been established.

The Fusemate gives a clear indication of the blown fuse and Fusemate should always be used in conjunction with
 industry standard safety precautions when working on energized LV circuits.

Live Cable Jointing :

A special adapter kit is available to permit the Fusemate to be temporarily connected in parallel when making a cable
joint. This allows the jointer working on live LV cables to establish that there is no fault on the cable prior to
beginning work and to complete the joint safely.

Safety                  : Inherently safe design.
Remote operation : Via a low power radio keyfob up to 30m range.
Portability             : Light weight (2kg) and small size ideal for single man operation.
Ease of use           : Compact design and clear instrumentation enable quick and effective use.
Compatibility        : Fits JS and JP type fuse positions, even in linkboxes and polemounted fuse holders. There is also an
                              accessory to facilitate use on NH fuse systems (DIN 43620/IEC 269).
Reliability             : Rugged design allows operation under the most severe working conditions.

FUSEMATE can be used directly in :

• LV feeder frames.
• Pole-mounted fuse holders.
• Underground Distribution Boxes.

FUSEMATE can be also be used with adaptor kits in many other situations :

• With NH fuses.
• In live Cable Jointing procedures.
• Non-standard LV underground distribution boxes, kiosks and feeder frames.

REZAP FM

Fault Location.
Using years of experience, Kelman has developed sophisticated single ended fault location algorithms. Using impedance to
fault calculations combined with patented fault location theory, the REZAP Fault Master can estimate the distance to a fault.

All the voltage and current data needed to provide a distance to fault estimation is gathered by the REZAP FM when
installed onto a feeder with a fault condition.

The estimated fault location is given on the REZAP FM display to the staff on site, and can be used on both permanent
faults and on intermittent faults.

Using the estimation given by the REZAP Fault Master, it is usually easy to narrow the field of the search to less than 15%
of the cable network. The results can be used to start excavation right away, or to enable a targeted installation of DELTA
V fault location technology.

Features

Data Logger.
The REZAP Fault Master has a data logger that will record voltage and current waveforms when triggered on over
current or under voltage using programmable levels set with the REZAP Connect software.

The information from the data logger can be used to determine the severity of the fault and to estimate if the fault is close in
to the substation, or lies further out on the feeder. The information is loaded directly from the REZAP Server and can be
saved to a local file to e-mail and print. The data can also be saved into a CSV formatted file.

Load Profiler.
The Load Profiler built into the REZAP Fault Master takes an average reading of the current flowing over each hour, as
well as additional readings. REZAP Load Profiler software displays these readings for the last few days, allowing an
engineer to determine if a fuse is blowing due to intermittent fault activity or overload conditions.

Message Forwarding.
SMS and e-mail messages can be sent to engineers and other staff when a fault becomes active. Messages can be sent
from individual installations or from an entire area. It is possible to set up message rules while the REZAP Fault Master
is powered off.

TTL Auto Reset.
The REZAP Fault Master Trips to Lockout (TTL) counter can be automatically reset to the default value after a
specified period of fault inactivity. This will reduce the number of times an engineer will need to attend to their REZAP
Fault Masters, but will ensure that adequate protection is provided for highly active faults.

Location Service
When a REZAP Fault Master is installed and closed, it will request a GSM based location lookup. The result from
this is stored on the REZAP Server, and can be accessed through the REZAP Control Centre Software.

Reporting
Control Centre software can be used to create reports about fault activity. It can collate information like CML’s for
substations, regions and individual REZAP Fault Masters. This is useful for gathering information for IIP reporting.

Fault Management REZAP  Control Centre Software

REZAP Control Centre software.
The REZAP Control Centre Software is used to manage the fleet of REZAP Fault Master units installed on your
distribution network. REZAP Control Centre allows you to filter information by area, by substation or by individual
installation. Events and Records that a REZAP Fault Master has generated can be viewed, along with Alarms and
Warnings from new events. The Control Centre software can be installed on computers across your organisation,
and can connect to the information held on the REZAP Server via a LAN, WAN or internet connection. Information
from REZAP Fault Master units is stored as events. The REZAP Control Centre allows staff to look at the events to
see what activity there has been since the REZAP was installed.

Remote Communications

Overview.
The REZAP Fault Master is equipped with a comprehensive communication system. Using a GPRS Enabled SIM
Card, the REZAP Fault Master sends data from the field to a server via the internet. The server forwards the
information to the appropriate staff by SMS message and e-mail.

REZAP Server.
The REZAP Server is the backbone of the REZAP communications infrastructure. It receives information from REZAP
Fault Masters in the field.  Information is stored against the substation name and location, and is forwarded to staff who
have requested information to be sent to them via SMS and e-mail.

The server also allows engineers to remotely configure and operate the REZAP FM from their laptop or office computer
using Connect Software.

*Note that a REZAP Server is required to avail of REZAP Fault Masters communications dependant features.

They can also look at data from the Datalogger using Record Viewer software and determine if outages are caused by
faults or overloading using the Load Profiler software.

Engineers and Admin staff can check the information coming from active REZAP units using Control Centre software .

Remote Operation.

REZAP Connect.
The REZAP Connect software allows an engineer to configure and operate the REZAP Fault Master. The software can
connect to the REZAP Fault Master remotely using the GPRS antenna via the internet, or directly using the provided serial
connection cable.

Reducing Engineer Workload.
Remote operation can save many trips to site when simple configuration settings are to be changed or a reclose operation
is to be attempted after a fault condition has led to lockout.

REZAP configuration.
Basic setup of the default Trip to lockout settings, reclose and reclaim time, and the protection rating can all be configured
remotely using the Connect software.

Connect software also provides important information about the condition of the REZAP Fault Master. It can read events
and records stored in the REZAP Fault Master directly, and allows configuration of the datalogger and load profiler functions.

Fault Thumping and Mobile Controller

Fault Thumping Mode.
Once a fault has been conditioned and becomes permanent, it can be found by ‘thumping’. To thump a cable, an engineer
stands over the suspected fault location and the REZAP FM is closed onto the fault. If a loud ‘thump’ is heard from the
ground, then the fault position has been found.

Fault Thumping Mode will allow approximately an extra 20% energy above the maximum fuse rating to pass, creating a
louder ‘thump’ in the ground. This is especially useful when used in conjunction with the Mobile Phone Controller.

Mobile Phone Controller.
An engineer can pair his mobile phone to the REZAP Fault Master in the substation, and then walk the cable route while
controlling REZAP operation. Information about BUS and FEEDER voltage as well as instantaneous current can be seen
on the mobile phone. It is possible to trip and close the REZAP Fault Master, as well as perform a Fault Thump type close
from the engineers mobile phone.
