Power System Automation
Data acquisition
Data acquisition refers to acquiring, or collecting, data. This data is collected in the form of measured analog current or voltage values or the open or closed status of contact points. Acquired data can be used locally within the device collecting it, sent to another device in a substation, or sent from the substation to one or several databases for use by operators, engineers, planners, and administration.
SupervisionComputer processes and personnel supervise, or monitor, the conditions and status of the power system using this acquired data. Operators and engineers monitor the information remotely on computer displays and graphical wall displays or locally, at the device, on front-panel displays and laptop computers.ControlControl refers to sending command messages to a device to operate the I&C and power-system devices. Traditional supervisory control and data acquisition (SCADA) systems rely on operators to supervise the system and initiate commands from an operator console on the master computer. Field personnel can also control devices using front-panel push buttons or a laptop computerIn addition, another task is power-system integration, which is the act of communicating data to, from, or among IEDs in the I&C system and remote users. Substation integration refers to combining data from the IEDs local to a substation so that there is a single point of contact in the substation for all of the I&C data.
Power-system automation processes rely on data acquisition; power-system supervision and power-system control all working together in a coordinated automatic fashion. The commands are generated automatically and then transmitted in the same fashion as operator initiated commands.
TESLA 4000is an intelligent, state of the art, user-friendly multi-timeframe dynamic power system recorder with advanced Phasor Measurement Unit (PMU) and Continuous Disturbance Recording (CDR) capabilities.
TESLA 4000 is an easy-to-use and cost effective, state of the art, multi-time frame (simultaneous) power system monitoring recorder. The integrated Phasor Measurement Unit (PMU) functionality streams synchrophasor data for wide area monitoring.
The TESLA creates records simultaneously in three time domains - fault (fast), dynamic swing (slow) and trend records and also creates event logs.
The CDR creates continuous records without triggers which together with the fault, swing and trend records provides wide area visibility of system performance. The CDR also creates redundancy in PMU data.With these powerful recording and communication capabilities, the TESLA recording systems provides the most versatile and complete monitoring of power system health.

iCBseries comprises embedded pole type vacuum circuit breakers for medium voltage and indoor use. They are suitable for three phase AC operations for 12kV, 17.5kV, 24kV and 36kV and are used for the protection of the electrical equipment in various industries, mining, and especially for medium voltage distribution sub stations, together with suitable air-insulated cubicles.
The iCB used German Technology and is available in complete series for medium voltage and for all commonly used rated currents, from 630A to 4000A, and for rated breaking current up to 40kA. The iCB circuit breaker come with a mechanical lifetime of 30, 000 operations.
The embedding with epoxy resin covers the vacuum interrupter as well as the upper and lower contacts of the circuit breaker, thus creating a full insulation for the internal electrical circuits. The embedding is done with a fully automated process, the APG (automated pressure gelatin) process. Thus, the iCB is no longer subjected to environmental hazards, and is fully maintenance free in this aspect.
A special flexible bedding fills the space between the vacuum interrupter and the epoxy resin, creating a cushion that responds to all thermal expansions and contractions, safeguarding the iCB from the occurrence of any electrical gap and therefore flash overs.
The embedded pole technology protects the circuit breaker from shock and mechanical stress, pollution and condensation. Flash overs between the interrupters are now virtually a thing of the past. Also, the creep age length of the interrupter and therefore the voltage withstand level (BIL) of the circuit breaker increase dramatically, opening new dimensions in cubicle design.
The use of modern, small-size vacuum interrupters with first class technology, the above features ensure the highest level of reliability for the iCB circuit breaker.
While meeting all relevant standards, with a lifetime of over 30, 000 mechanical operations, and the ability to function as a recloser, the iCB can surely meet the highest demands of the industry.
Last not least, the high level of automation and technology used make the iCB also economically competitive and interesting for panel builders around the world.

iSISis now the switchgear (up to 40.5 kV) with the smallest foot print in the world, reducing the foot print to 50% of GIS switchgear. ISIS is also the greenest switchgear as the insulation is provided by patented solid insulation technology and as such eliminates completely the use of green house gas of SF6. It has other patented features like phase segregated, independantly earthed and metal clad poles, and all active components are insulated with special patented epoxy material, making iSIS extremely safe from fire, explosion and water.
Thus, iSIS will be an ideal replacement for the GIS around the world, in all applications where space is critical like in large metropolitan cities, windmill applications, offshore platforms etc. where safety is paramount like in oil, petrochemical, chemical and pharmaceutical industries and in all countries which are increasingly banning the use of SF6 gas in switchgear.
