NME 200
A Fast and Powerful Electric Maneuver Device
NME 200 is a maintenance free electric motor driven operating device for supervision and control of polemounted air-break switches, load break switches and disconnectors. Utilizing rare earth magnet motor
technology, NME 200 has the power to operate even the most stubborn units with the speed to make the
operation safe.
NME 200 has a flexible interface so it can be used in the
following modes;
• Remote operation via Radius RNO data radios
• Remote operation using DNP3, 60870-5-101 or IEC
60870-5-104 interface
• Hardwire interface to a local SCADA RTU
• Local operation using an operator’s panel
NME 200 is designed to operate in a wide range of switch
applications. The motor switch operator can be used in
conjunction with the following communication alternatives.
Radius RNO Data Radios
For any remote device, the key to its successful operation is
the communication between the device and its host.
Netcontrol has been providing such communication systems
for the electricity industry for decades and has designed a
number of radio modems, which provides the security and
robustness needed for these applications. Netcontrol provides
a fully SCADA integrated communication system. Netcontrol
offers a range of dedicated data radios which utilize a
compressed protocol with mesh technology. They have high
signal recovery resulting in a reliable wide area networked
remote control and lower costs.
Operational Features
The robust mechanical cabinet hosts a rare earth magnet
motor device creating a safe and rapid maneuver. The
typical operation duration for NME 200 is under one
second. The device is normally remotely operated but can
also be controlled locally by an operator’s panel. The panel
is designed to be clear and easily understood. Indications
such as switch position, battery status and charging status
are easily viewed. A battery test can be performed at any
time to check the condition of the batteries.
NME 200 fits seamlessly into radio network. RNO data radios
are event triggered to maximize spectrum efficiency. Each
unit can also act as a repeater forwarding messages to other
units. Any message has the ability to pass through four other
units before reaching its destination. RNOs communicate with
a central radio which can be integrated into a SCADA system
and can utilize industry protocols such as DNP3, IEC 608705-101 and IEC 60870-5-104.
Stored Energy / Battery Management
NME 200 is provided with a rechargeable battery
solution to ensure continued operational performance
beyond the loss of supplied voltage.

3rd Party Communication
The NME 200 cabinet temperature is thermostatically
controlled and the battery charging is temperature
compensated to ensure battery health. A calibrated load
further tests the batteries at configurable time intervals to
ensure that their health has been maintained.
NME 200 prevents battery discharging beyond their
minimum charge level by measuring the battery capacity
at regular intervals and subsequently disconnecting the
batteries from the circuit, prior to this minimum level being
reached. The host system is kept informed of battery status
via a number of remote status alarms, which are also
displayed on the local operator’s panel.
Local Operation with Hit & Run Function
NME 200 has a local control panel that can be used to open
or close the load switch. Critical status information such as
switch position and battery status is displayed at the panel.
A lamp test gives the operator confidence that no alarms are
missing.
The unit can be switched to either ‘local’ or ‘remote’ mode
and for additional safety can be switched to an ‘off’
position which prevents both local and remote operation.
Safety is paramount and therefore to perform a local operation
the operator must press an ‘activate’ button before
pressing either the ‘open’ or ‘close’ in order to avoid
unintentional operations.
Integrated Self-Sectionalizing Function
NME 200 has an optional integrated self-sectionalizing
function. When a line disturbance occurs, a selfsectionalizing routine starts. The user can configure how
the system works, by setting various timing and reclaim
parameters. The device will open within the dead-time of an
upstream breaker and will close when the voltage returns
for a preset period. If it closes into a fault, it will open and
lockout in the next dead-time. This makes the device ideally
suited for spur lines as well as main sections. All information
is reported to the customer’s control centre for immediate
real time monitoring.
For additional safety the unit can be programmed to allow for
”Hit & Run” operation, which allows the operator to move to a
safe distance from the switch after pressing the local
maneuver control.
NME 200 can be supplied, as an option, with a DNP3, IEC
60870-5-101 or IEC 60870-5-104 protocol interface,
allowing it to be integrated into an existing SCADA system.
The communication medium is then free so NME 200 can
communicate to the host via a range of different options from
TETRA radio to fiber optic or cellular. Netcontrol provides their
PDR range of digital data radios, which allow wide high-speed
communication to the host system. By using a mesh type
technology with repeating functionality it can cover very wide
geographical areas.

NME 200 can be deployed in a large switching station and can
be hardwired via in-built terminal interfaces to the
existing switching station marshalling cabinet and SCADA
RTU. Control and monitoring are via opto-coupled interfaces
and volt-free contacts. Power for the motor is derived from the
battery in NME 200 and thus there is no concern about
voltage drop along the cables to the unit.

A handle is provided that can be used if a manual operation
is required. Inserting the handle in to its operating position
disengages a clutch, decoupling the motor and allowing the
operator to freely move the switch. The handle is designed so
that it can be left in position and padlocked, thus preventing
manual, local or remote electrical operation.
