Reliability through design excellence

The Cyberex brand has been an industry leader in the design and development of mission critical

systems that ensure uptime and business continuity for customers across the globe. 

We recognize that every customer has unique electrical requirements and we work closely with them to

develop solutions that solve their most difficult challenges.

SuperSwitch®4 provides maximum reliability through its innovative design.

The modular components, from the power stage to the redundant bus architecture,

have been engineered to unprecedented standards.

The SuperSwitch®4 is available in select cabinet sizes that cater to your serviceability requirements.

Its standard ultra-dense design maximizes physical floor space. Front access is required for operation

and removal of serviceable components, while one side or rear access is required for installation and

tightening of customer connections. A full front access cabinet design is also available for complete

operation, maintenance, installation and IR scanning accessibility.

Fully rated hockey puck SCRs are employed to prevent system damage after load faults.

The superior cooling design of the assembly enables higher current applications.

Infrared scans are easily accomplished without removal of assembly.

Connections and maintenance are made easier by staggered phase connections and ample gutter

space. 100% of connections are torqued ensuring maximum reliability.

SuperSwitch® 4 redefines reliability

Forty years ago, Cyberex revolutionized power distribution with its invention of the digital static

transfer switch (STS). Since then, building on the innovation of ABB engineering and the technological

advancements and commissioning of the most extensive installed base of STSs worldwide,

the SuperSwitch®

4 has evolved. Designed with a ‘true’ fault-tolerant architecture, SuperSwitch®4 ensures

there is truly no single point of failure through the use of our patented transfer algorithms and robust

electrical components. With an increased MTBDE to an estimated 1.5 million hours, SuperSwitch®4

reliability is unmatched. SuperSwitch®4 redefines power reliability with its exceptional design,

serviceability and user-interface.

Current protection

Instantaneous phase overcurrent protection (PIOC, 50)

The instantaneous three phase overcurrent function has a low transient overreach and short tripping

time to allow use as a high set short-circuit protection function, with the reach limited to less than

typical eighty percent of the power line at minimum source impedance.

Four step phase overcurrent protection (POCM, 51_67)

The four step phase overcurrent function has an inverse or definite time delay independent for each

step separately.

All IEC and ANSI time delayed characteristics are available together with an optional user defined

time characteristic.

The function can be set to be directional or non-directional independently for each of the steps.

Instantaneous residual overcurrent protection (PIOC, 50N)

The single input overcurrent function has a low transient overreach and short tripping times to

allow use as a high set short circuit protection function, with the reach limited to less than typical

eighty percent of the power line at minimum source impedance. The function can be configured

to measure the residual current from the three phase current inputs or the current from a separate

current input.

Functionality

Differential protection

High impedance differential protection(PDIF, 87)

The high impedance differential protection can be used when the involved CT cores have same turn

ratio and similar magnetizing characteristic. It utilizes an external summation of the phases and neu

tral current and a series resistor and a voltage dependent resistor externally to the relay.

The single input overcurrent function has a low transient overreach and short tripping times to

allow use as a high set short circuit protection function, with the reach limited to less than typical

eighty percent of the power line at minimum source impedance. The function can be configured

to measure the residual current from the three phase current inputs or the current from a separate

current input.

Four step residual overcurrent protection (PEFM, 51N/67N)

The four step single input overcurrent function has an inverse or definite time delay independent for

each step separately.

All IEC and ANSI time delayed characteristics are available together with an optional user

defined characteristic.

High set instantaneous phase and earth overcur rent, 4 step directional or un-directional delayed

phase and earth overcurrent, thermal overload and two step under and overvoltage functions are

examples of the available functions allowing user to fulfill any application requirement.

Disturbance recording and fault locator are avail able to allow independent post-fault analysis after

primary disturbances with a single failure in the protection system.

6 x 32 dual directional channels for intertrip and binary signals transfer is available in the commu

nication between selected IEDs inside the station or in a near-by station.

The advanced logic capability, where the user logic is prepared with a graphical tool, allows spe

cial applications such as automatic opening of disconnectors in multi-breaker arrangements, closing

of breaker rings, load transfer logics etc. The graphical configuration tool ensures simple and

fast testing and commissioning.

Serial data communication is via optical connections to ensure immunity against disturbances.

The wide application flexibility makes this product an excellent choice for both new installations and

the refurbishment of existing installations.

Installations with rectangular load cells below the lower back up roll or above the upper back up roll:

Accessible parts: Mounting surfaces in the mill stand, the sledges if present, the rockers,

the pressure plates closest to the load cells and

intermediate mating plates if present.

Installations with circular load cells under the screw-down or hydraulic cylinder:

Accessible parts: Mounting surfaces above the upper back up roll

bearing chuck, plain or tapered thrust roller bearings, pressure plates

closest to the load cells and other intermediate mating plates if present.

Installations with annular load cells above the screw-down inside the mill stand:

Accessible parts: Mounting surfaces of the screw-down nut, plain or

tapered thrust roller bearings, pressure plates closest to the load cells.

The parts and mounting surfaces mentioned above need to be accessible

before the start of the work or otherwise the investigation of

them need to be planned for in advance so that it can be performed

later during the site visit.

Service duration

Typically 1 day on-site to inspect the roll force measurement installation, evaluate and give

recommendations if further actions are needed.

During at least 4 hours, load cells and pressure plates need to be accessible outside the mill stand

for inspection and testing. This can be done during a planned maintenance stop, or by the customer

exchanging to spare load cells and spare pressure plates in the mill stand in advance.

Additional time for travel, preparation, analysis and reporting is needed.

Note: Free access to the mechanical parts and the mounting surfaces 

in the actual mechanical installation is essential for achieving

the expected goals with the Health Check during the site visit. The

accessible parts required for different load cell types and positions

in the mill stand are listed below.
