1 Product Description

1.1 Product Application Field
Reclosers can be applied in overhead distribution lines. The main applications are:
Clearing transient faults by performing autoreclosing;
Isolating sustained faults in the overhead line network;
Isolating sustained faults in a network where conventional protection coordination is not possible;
Automatic backfeed restoration.
The recloser can also be used at outdoor substations feeding overhead distribution lines for:
Substation outgoing feeder with autoreclosing functionality;
Substation busbar coupler with backfeed restoration capability;
Substation switchgear incoming feeder breaker with overcurrent protection for busbar faults, undervoltage
protection for backfeed restoration purposes and interfaces for transformer non-electrical protection.
1.2 Product Main Components
Outdoor Switching Module1.2.1
The OSM is equipped with six high voltage bushings with embedded current and voltage sensors.
The bushings are covered by silicone rubber insulation and mount on the top of the tank and provide
500 mm (OSM15) or 860 mm (OSM25) creepage distance.
The bushings are marked with the terminal designation X1, X2 or X3 for the default source side and X4, X5
or X6 for the default load side. The source and load side can be reversed in the RC settings if required.
Figure 1
General arrangement of the OSM15_Al_1(5)
1.2.1.1 OSM Housing
The OSM tank is made of corrosion resistant anodized aluminum alloy. The tank is coated with light gray
RAL 7038 powder coating. Threaded holes (M12x30) on each side of the tank allow the application of
various kits and OSM installation on various poles and structures. These threaded holes can also be used to
install a set of lifting lugs on the tank. The earthing provision (M12x30 threaded hole) is labelled for
identification.

OSM25_Al_1(5) housing
1.2.1.2 Mechanical Trip and Lockout Mechanism
A mechanical trip hook is located at the bottom of the tank (Figure 3). When the hook is pulled down, the
OSM is mechanically tripped, locked in the OPEN position and electrically isolated from the driver. An “OSM
Coil Isolated” warning event is generated by the RC5_4 to provide indication of the locked state. The OSM
remains locked and cannot be operated until the trip hook is pushed back into the operating position.
Figure 3
Mechanical trip hook
1.2.1.3 Mechanical Position Indicator
The position indicator is located under a protective cover at the bottom of the tank and is clearly visible from
the ground (Figure 4). The indicator color is red when the OSM is closed and green when it is open.
Figure 4
Main contact position indicator

12
Recloser Control Cubicle1.2.2
The RC5_4 recloser control cubicle is made from powder coated aluminum, the same as the OSM tank.
The RC5_4 main components are shown at figure below.
Figure 5
RC5_4 with internal door closed
Figure 6
RC5_4 with internal door open
The external door has a padlock provision that is suitable for a shackle with up to a 12 mm diameter.
The external door can be securely fixed in the open position.
The anti-vandal cover is fixed from inside the housing with one captive screw. It protects the umbilical cable
from unauthorized disconnection.

13
Figure 7
Control cable connection
The RC5_4 cubicle is equipped with stainless steel earthing provision with M12x30mm bolt: All internal
components and parts are earthed to the main RC cubicle with 2.5 mm2 copper earthing jumpers.
The housing has provisions for protection against dust and water ingress.
Figure 8
RC housing provisions
The RC5_4 is equipped with a Door Position Switch which is used for disabling the CPM at closed RC, as
well as a SCADA indication of the RC door position.
The door position switch is mounted on the internal door and actuated by the lever mounted opposite to the
switch on the external door (Figure 9).

1.2.2.1 Control Panel Module (CPM)
The CPM provides local control and indication functions of the Rec15/25 (Figure 10). Control buttons and
indication LEDs are located at the front side of the CPM (Figure 11). The CPM has an integrated USB
interface for PC connection.

1.2.2.2 Recloser Control Module (RCM)
The RCM is the recloser control module. The RCM provides protection, communication, measurement and
control functions.

1.2.2.3 Power supply filter module (PSFM)
The PSFM is used for an RC5_4 auxiliary power supply connection (Figure 14). This module provides
impulse noise protection for all internal modules of the RC5_4.
Figure 14
Power supply filter module
1.2.2.4 Rechargeable Battery (BAT)
The rechargeable battery provides the RC5_4 with auxiliary power when the main auxiliary power is not
present. The power supply system is designed to provide battery optimum charging and optimize battery
lifetime.
Technical parameters of Rechargeable Battery are in Table 7.

17
1.2.2.5 Input/output module (IOM)
The RC can be supplied with an IOM (Figure 15) module on request It provides control and indication
functions with the aid of digital inputs/outputs.
Figure 15
Input/Output module
The IOM contains twelve digital inputs and twelve digital outputs. The location of these connectors
(marked “15”…”18”) with these inputs and outputs are shown in Figure 16.
Figure 16
Location of IOM connectors
Digital inputs are potentially isolated by means of opto-couplers (Figure 17).
Figure 17
Digital inputs
Bistable relays with changeover contacts are used for the digital outputs as illustrated in Figure 18.

Technical parameters for Ethernet interface in Table 9.
Wired ethernet module starts working automatically after Network settings setup for corresponding interface
is completed. LED indication description:
Green LED –Indicating the network connection speed.
Glowing continuously –Aprox 100 Mbs;
No indication –Less than 10 Mbs;
Default setting is 100 Mbs;
Yellow LED –Packages transmitting is active.
No LED indication –Ethernet module disconnected.
Ethernet module operation is continuously monitored by the controller. Automatic restart for Ethernet module
will be initiated in case device hanging will be detected.
Optical Ethernet module
Optical Ethernet module provides full remote (SCADA) and local communication and engineering
functionality via optical fiber SC/ST interface.

1.2.2.7 Wi-Fi Module (WFM)
The RC5_4 can be supplied with a Wi-Fi module in request.
The Wi-Fi module provides full remote (SCADA) and local communication and engineering functionality over
wireless TCP/IP connection.
It is connected to the RCM via a USB cable (Figure 21).
Figure 21

Technical parameters of Bluetooth module are in Table 12.
1.2.2.8 Bluetooth Module (BTM)
The RC can be supplied with a Bluetooth module on request.
The Bluetooth module provides point-to-point wireless connection between the RC and a personal computer.
It is connected to the RCM via a USB cable (Figure 21).
Technical parameters of Bluetooth module are in Table 11.
Control Cable1.2.3
The umbilical control cable (Figure 22) connects the OSM actuators, metering and auxiliary wiring to the RC.
Control cable wires are protected by PVC coated steel armored sleeve. The cable is equipped with a heavy
duty 42 pin male connector on the OSM side and heavy duty 32 pin female connector on the RC side. The
connection is made using heavy-duty connectors. These connectors exhibit excellent mechanical properties
and prevent rust.

20
Advanced CVCSs, control module (CM) and the circuit breaker technology allows unplugging the umbilical
cable when the device is in operation. The position of the main contacts will remain the same, as when the
umbilical cable is plugged unless there are preprogrammed actions. There are no hazardous voltages from
either side of the unplugged umbilical and it will not cause any injury.
The umbilical cable can be plugged in when the main line is energized.
