Schneider Electric design
NEXgulf design has been achieved thanks to full up-to-date means such as
computer aided design software, synthetic laboratories, simulation of
behaviour…
NEXgulf is designed according to the best practices in terms of installation,
operation and maintenance:
reliability: the user benefits from the expertise developed by Schneider
Electric in the area of operating dependability for more than 45 years,
simplicity: little effort is required for local manual operations, iconillustrated instructions on each front panel make the operating sequence
and switching device status very simple to understand,
safety: very comprehensive set of mechanical interlocks prevents
operator errors.

Strict and systematic checks
During its manufacture, each NEXgulf is subject to systematic routine
testing, intended to check both quality and conformity:
measuring of operating torque,
dielectric test,
testing of safety systems and interlocks,
testing of low voltage components,
conformity with drawings and diagrams.
The results obtained are given by the quality control department for each

Vacuum circuit breaker
Evolis circuit breaker
from 1 to 17.5 kV with vacuum technology
Evolis circuit breaker equips the cubicles type IF11, IF12, C11 and C12
for voltage values of between 7.2 kV and 17.5 kV.
Evolis circuit breaker is used to protect & control MV public or industrial
distribution networks.
High electrical endurance
A magnetic field is applied in the axis of the vacuum interrupter contacts.
The process maintains the arc in diffused mode even at current values.
It ensures optimal dispersion of the energy over the contact surface and
avoids localized temperature rise.
The advantages of this technique are:
a very compact vacuum interrupter,
low energy dissipation of the arc in the vacuum interrupters.
Evolis is in conformity with the highest electrical endurance class
(IEC62271-100: class E2).
High mechanical endurance
This magnetic field is generated by a patented external coil which surrounds the contact zone.
This solution provides many advantages:
a simplified and therefore reliable vacuum interrupter,
heavy duty contacts which do not distort during repeated switching
operations,
considerable reduction in control mechanism energy.
The Masterpact control mechanism used on Evolis provides the
benefits of a system that has proven itself for over 10 years on
hundreds of thousands of installations.
Evolis is in conformity with most demanding mechanical endurance
class (IEC 62271-100: class M2).

Protection Chain
Sepam: protection, monitoring and control units
Sepam is a range of digital protection, monitoring and control units and is
at the centre of the protection, monitoring & control system for NEXgulf
functional units: all the necessary protection, metering, control, monitoring
and signalling functions are carried out by Sepam.
Like the NEXgulf range, the Sepam range is a range of units defined to
provide an optimal solution for each application and includes:
Sepam S type: substation incomer and feeder,
Sepam B type: bussectioning,
Sepam T type: transformer feeder,
Sepam M type: motor feeder,
Sepam C type: capacitor feeder,
Sepam G type: generator feeder.
Sepam advantages
Sepam, a digital multi-functional protection unit, provides you with the
following advantages:
simple to use for better daily efficiency: user-machine interface (UMI)
which is ergonomic and which provides comprehensive & clear information
to operators.
simple to incorporate: flexibility and user friendliness of parameter setting
software and simplified tests.
money saving:
integrating all functions required in one single, ready to use product,
upgradeable solution, to spread the cost of investment over time.
centralized NEXgulf switchboard management:
Sepam is easily integrated into all network control systems, due to its
Modbus communication interface,
all data required for installation monitoring and control are accessible
through the Modbus communication.
better network knowledge through the oscillo-disturbance recording
function & measurement of the imbalance ratio, motor operation
parameters, etc.
Modbus communication architecture
16
NEXgulf
improving continuity of service:
through effective preventive equipment maintenance using switchgear
diagnosis functions: time and number of operations, sum of breaking
currents2A
, etc.
through clear and comprehensive information, both locally and remotely,
reducing the time needed to act in the event of a fault.

Measurement & Control
Power monitoring and control devices
The PowerLogic Power Meter is a cost effective, high performance meter.
It can operate as a stand-alone device or as part of the power monitoring
and control system from Schneider Electric: the PowerLogic system (1).
Essential power monitoring
revenue-class; accuracy 0.1 % current / voltage,
on-board memory for energy consumption analysis,
on-board clock / calendar for time / date stamping.
Application flexibility
separate meter and display modules,
direct-connect up to 600 V: higher voltages with PTs.
Other devices, such as the PowerLogic Circuit Monitor Ionmeters, are
availablefor MV & LV networks. Main functions include comprehensive
power monitoring, power quality analysis, recording and optional
input and output control.
Earthing Switch
An earthing switch is used to earth and short-circuit the cable ends before
work is performed on the cable. The switch incorporates the following:
designed for making capacity,
a fast-acting closing mechanism independent of the operator,
a locking device which will not allow it to be operated until the circuit
breaker has been opened and withdrawn,
3 voltage capacitive dividers incorporated into the insulators which
support the terminal plates, and connected to three “neon” indicators
mounted on the front plate, to indicate whether the cables are live or dead.
Voltage Presence Indicating Systems are in compliance to IEC 61958.
