High Voltage Testing Market to Observe Strong Development by 2026
The
availability of electrical energy is vital for the economic
development and quality lifestyle. Any electrical equipment must be
capable of withstanding over-voltages during the operation. This can
be assured by suitable testing techniques and testing equipments.
High voltage testing can be broadly classified into tests on
completed equipment and on insulating materials. The tests carried
out on sample of dielectric consist of measurement of dielectric loss
per unit volume, dielectric strength of the material and
permittivity. Test carried out on completed equipment are the
measurement of capacitance, power factor, ultimate breakdown voltage
and flash over voltage. The break down voltage test on completed
equipment is only done on a few samples since it permanently damages
and destroys the equipment from further use. Breakdown voltage
equipment is subjected to withstand test on which the voltage applied
is about twice the normal voltage. Various types of used in testing
are DC hipots, AC hipots, oil dielectric tester, AC dielectric test
sets, aerial lift and bucket truck tester, cable fault locator, surge
generators, VLF, HV divider and tan delta. Distribution and
transmission are the application of high voltage testing products. At
higher voltage, reliability and proven track record become even more
important.

High
Voltage Testing Market: Drivers & Restraints
In
U.S., Europe and China, the most common transportation voltage level
is 550 KV. Canada, Korea and U.S are tending to use 800 KV which is
also applied to India and China. This is due to longer distances of
power transmission, requiring higher voltage to minimize transmission
losses. Increasing transmission voltage levels, current for a given
power is reduced to lower levels hence resulting in requirement of a
thinner and a lighter cable which can easily withstand such lower
current levels. Emerging economies like China and India will support
the need for higher transmission voltage to increase the capacity.
High voltage testing equipment market demand in Asia-Pacific is
constantly rising making it the most attractive market specifically
in China and India. In Europe, high and extra-high voltage
underground electricity cable systems rated at 220KV and above have
become part of the backbone of modern day power transmission
infrastructure.
In Europe shift towards usage of underground high voltage cables instead of currently in place overhead transmission
lines is expected to help in improving connectivity and reliability
as compared to overhead lines. China and U.S. are two leading
high-voltage switch gear markets in the world attracting huge
business. Main drivers in China are several power generation,
transmission and upcoming pipeline projects. User-friendly
high-voltage test systems for on-site testing are of great interest
for the Chinese cable industry. Growth in Russian market will be
driven by new power transmission lines and up gradation of existing
ones. In U.S., growth is expected to be driven by increased
investment in transmission and distribution infrastructure and
replacements.
