Insulation Megger Resistance Test
The Megger test indicates the condition of ground insulation. However,
it does not measure the turn-to-turn state of the insulation, and may
not register localized weaknesses. Insulation Megger resistance tester
is used to measure the insulation resistance of all types of electrical
equipment. Megger resistance tester performs automatic tests, enabling
consistent operation without operator input and the instrument can also
store the results and can be operated from PC.
Megger Extended Range Insulation Resistance testers- 2101070 and 210600
When high ranges are needed for measuring insulation resistance megger
extended range resistance testers are used. The extended resistance testers
come in series of 210170 and 210600. These two testers provide excellent
test voltage regulation and an external guard terminal to eliminate surface
leakage current from the measurement. The features of these resistance
testers are that they are electronic and generate a regulated direct
current high voltage and use low-zero drift. The measurements of these
testers are of highly accurate due to the high-accuracy circuits with
high current sensitivity. These instruments are portable and come in
a molded, impact resistance, flame -retardant case.
Megger MIT300 Series-Insulation Testers for Electricians - latest
Electricians use this new series of insulation testers from megger as
they guarantee high accuracy combined with stability of calibration.
In this new series all the insulation test instruments provide indication
of insulation resistance up to 999Mohms, 200mA continuity buzzer and
facilities for nullifying the resistance of the test leads. The entry-level
range offers insulation test voltages of 250V and 500V and the higher
range models allow testing at 250V, 500V and 1,000V. In addition to the
basic features, the Megger MIT300 series adds a default voltmeter function
with a backlit display, illuminated range panel, insulation limit alarm,
resistance measurement, and an adjustable threshold for the continuity
buzzer. The model MIT330 of the latest Megger series of insulation testers
come with a downloadable software and has the ability to store and download
test data for up to 99 jobs. The MIT310, and MIT320 testers incorporate
dual solid-state displays which simultaneously show the test results
numerically and also in the form of a moving-arc bar graph. The main
features of the instrument of this series are that they are easy to use
and come with a warranty period of three years. These instruments have
a backlit LCD display, voltmeter function and storage and download capacity
is available in the higher series. All the equipments come in tough rubber
armored case that is weather proof.
Cellulose insulation
Cellulose insulation is an energy saving insulation product made from recycled newspapers. Cellulose-a material used as wobbly fill insulation is made from recycled wood fiber, primarily newsprint. The wood fiber is ragged and crushed into small,...
Reflective Insulation
Reflective insulation is one kind of home insulation techniques. The use of foil in insulation has gained importance because of versatile features such as being light-weight and resisting all three types of heat transfer; conduction, convection and...
Soundproof Insulation
Soundproof a home is more effective if the installation is taken up at the construction stage itself. This will also make it less expensive. Total soundproofing may not entirely be possible in an existing building. However, there are many soundproof...
