Market Research Added A New Report "High
Frequency, High Voltage Advanced Winding Analyzers And Surge Testers
Market". Advanced winding analyzers and surge testers
are being widely used as standard calibrating instruments.In the past
decade the electronic and electrical industry saw the advent of many
technically advanced instruments being used in various fields. The
ease of usage and efficiency provided by this equipment haveaugmented
the increase in demand for electronic and electrical equipment.
However, the demand of this equipment depends upon the reliability
and efficiency provided by device.High voltage testing has gained
significance in the past decades due to this factors. Advanced
Winding Analyzer and surge testers are used for trend analysis which
will prevent downtime due to less equipment failure and give
increased equipmentreliability.
Surge testers use
the principle of impedance balance to test the quality of electrical
windings. They act as a capacitive-discharge system. A capacitor is
charged with high voltage and then discharged into the winding,
through a solid state assembly. This sequence is repeated thus
stressing the insulation of the winding with high voltage pulses. The
resulting voltage decay pattern of two winding is then displayed on
the CRT. The waveform pattern will be perfectly superimposed for good
windings but in case of a defective winding a double wave pattern
will appear on the screen as one wave pattern from the good winding
plus the erratic pattern from the faulty winding. Surge testers not
only tests ground insulation, but more importantly, it tests
turn-to-turn coil-to-coil and phase-to-phase insulation. If as few as
one turn is shorted the surge test till detect this fault.Advanced
winding analyzersdetect and evaluate winding faults by simulating
conditions that equipment experience during startup and normal
operation. It performs all requested tests, stores the results, and
continuously monitors voltage levels while testing. If the analyzer
detects a weakness in the insulation, the test is interrupted, the
operator is alerted, and all test parameters at the time of the
interruption are reported. This analysis includes surge testing,
polarization index testing, DC high potential testing, winding
resistance testing, and insulation resistance testing.

However, traditional
analyzers and surge testers have several shortcomings. The test
results provided areless reliable. The operators working with the
instruments my lack awareness about the testers. Automation is being
used as an effective tool to overcome this problems. A computer and
IP network attached to the testers are used to display the accurate
result. The computers are also used to keep a record of the anomalies
in voltage. Thus it becomes to take preventive measures. Advanced
analyzers and surge testers are used for quality checks and spare
testing throughout the manufacturing process of coils, motors and
generators. Large screens, high operating frequencies and high
portability is inclining the market towards advanced winding analyzer
and reliable surge testing.
Power generation
sector is now transforming to equip advanced technology such as smart
grid, distributed generation network, micro turbines and utility
automation, among others. The usage of these instruments is under
planned deployment into smart-grid, power stations and substations as
electricity infrastructure upgrade. Analyzers manufacturers are using
research and development strategy to adapt the advancing equipment in
the market. Countries globally are shifting towards monitoring
electricity with emphasis on reduction in energy losses. These
factors have supported the demand of advanced winding analyzers and
surge testers. The testers available in the market are highly
advanced and multitasking.These instruments now offer tests that can
determine the entire system integrity and report in real time. Megohm
measurement, Insulation tests, polarization index tests, motor
current signature analysis, step voltage test, hypot tests, meg
tests, voltage power and efficiency data etc, are few tests provided
by high voltage analyzers and surge testers.
These instruments
can be segmented depending upon the end user such as industrial,
commercial, manufacturing firms and utilities. However, high cost of
testers is acting as a hindrance in the growth of its market. These
advanced equipment may witness growth in infrastructure and oil and
gas sectors. The developing nations such as China and India have
undertaken many projects for infrastructure and industrial
development. These factors will make Asia Pacific as an attractive
market for advanced winding analyzers and surge testers.
Some of the Major
Players in this market are Baker
Instruments, Electrom instruments, ALL-TEST Pro, LLC.,PdMA, SKF,
Renown Electric, Whitelegg machines Ltd., Stanley Electric motor
company, INC., Schleich and SPS electronics, among others.
