JetView 1004
JetView 1004
is a cost effective touch display on a high technological level.
Besidesexcellent performance, this device excels in its brilliant
LED display. Various interfaces,as well as an SDcard slot serve for
problem-free data exchange by means of JetView1004.
Peripheral devices can be connected to the touch panel via
USB port or the serial interface. For network connection, two
Ethernet interfaces withintegrated 100 MBit switch and a Gateway
function have been supplied.
The JetView1004 user interface can be dimmed. The brightness can
be setindividually. It makes easy working possible, even in
twilight or darkness. The built-inacoustic signal generator
produces alarm, indication or acknowledgment signals whichmake
operation easier.
Peripheral devices can be connected to the touch panel HMI via
USB port or the serialinterface. For network connection, two
Ethernet interfaces with integrated 100MBitswitch and a Gateway
function have been supplied.
The FTP server, as well as an SD-card slot, serve for fast and
problem-free dataexchange with the device.

TITLE : HIGH VOLTAGE DC TRANSMISSION (HVDC) AND HARMONICS
INTRODUCTION:
Historical background of HVDCtransmission.
1950 :
1954 :
1972 :
1990 :
1997 :
2000 :
Advantages of HighVoltage DC transmission.
Dis-advantages of HVDCtransmission
High Voltage DC Transmission involves stepping up and
rectification of the voltage is to betransmitted, to convert it
into high voltage DC and transmit it to a long distance of the
order of hundreds of miles. At the receiving end the high voltage
DC is inverted and stepped down to make itsuitable for power
distribution at the receiving end. This type of transmission has
advantages of economy and efficiency at the same time it has side
effects of harmonic generation. This paper gives thedetails of
these advantages and also gives themethodsof harmonic
mitigation.
116 Km transmission linewascommissionedbetween Moscowto Kasira
at 200KV.
The first commercial HVDC line was built with 98Km Submarine
cable with ground
return between island of Gotland and Swedish Mainland.
The Nelson River HVDC transmission line of 550 miles delivered
electric power of 2500MW, from Kettle generating station to
Winnipeg.
In India 1000MW Rihand to Dadri HVDC line was commissioned.
The first application of DC distribution system in Sweden of
HVDC is known as"HVDC light".
600V DC 785Km transmission line in Brazil.
1) HVDC is more efficient. This is because it is a DC
transmission at high voltage whichreduces thecurrentandhence the
IRlosses.
2) Transmitter and receiver can operate at different frequencies
this is advantageous in somecountries like Japan where part of the
country works at 50Hz and remaining works at 60Hz.
3) Power flowcan be inboth the directions.
4) DCinterconnection does not increase the maximum fault current
in eitherAC systems.
5) Deliveryof power isalmost atunitypower factor.
6) The power flow through HVDC transmission line can be
regulated against line and loadregulations.
1) HVDC transmission generates harmonics when at transmission
end AC power is rectified. At thereceiving the output of inverter
needs to be filtered to get pure sinewave.

You question, we answer
Effects of Harmonics
Mitigationof harmonics
CONCLUSION :
1) Each transmission line has many natural resonant frequencies
determined by its length,geometry and termination.The input
impedance of the transmission line can be closed to zeroand
resistive during series resonance or infinitely large during
parallel resonance at naturalresonance frequencies. If a series
resonance frequency is close to any of the dominantharmonics
generated by converter at transmission end severe telephone
interference isexpected.
2) Current harmonics injected by converter on transmission side
lead to voltage distortion.
3) Harmonics increase copper, iron and eddy current losses in
transformers, motors andgenerators.
4) Power factor improvement capacitors are stressed due to high
frequencyvoltage harmonics.5) The fuses, switch gears and relays
lead to premature failure/tripping causing shut downs of
pants.
6) Harmonics also reduce effective power factor.
1) 3-phase converter gives total current distortion of nearly
62%. However, 12 pulse converter gives 8% total harmonic distortion
of current and 18 pulse converter result in further reductionin
total harmonic distortion of current by reducing it to less than
2%.
2) Passive harmonic filter and Active harmonic filter which are
connected in shunt with theharmonics source can reduce the current
harmonics and can bring it within limits specified byIEEE 519:1992
standard.
If harmonics are taken care of HVDC transmission is the ideal
power transmission over long distance.

Question
Answer
Howtheefficiency of electrical lightingfixture is measured?
lumen 1 Watt efficacy.
LUXmeter.
Efficiency of the lighting fixture light is known as efficacy.
Normally we have seen thatthe efficiency of any system is a unit
less ratio of output and input power. But in case of lighting
fixture lights, the efficiency is not unit less and the unit is
Lumen / Watt.
How many are delivered by light by consuming of power is its
