Insulation testers: Regular maintenance in the
electrical industry requires testing for insulation resistance
tests from Megaohms to teraohms at 500V to as high as 10KV.With
features like variable test currents, automatic discharge of capacitance,
breakdown or burn modes, polarization index and PC interfaces
these Insulation testers are best for maintenance of motors, transformers,
generators, cables and switchgear.
Ground-Earth Testers: Soil resistivity measurements
are used to establish the best electrode design, a correct earth
system and site for geological or construction investigations.
These reliable instruments operating on 2 terminal or 4 terminal
modes offer variable test frequency and currents.Earth testing
spikes with test leads can also be made available.
RCD Testers: RCD tests are a must to check the effectiveness
of the RCDs in any wiring installation. With features like
a no trip test, trip test, timing tests,
the tester meets test requirements of IEC 364, HD 384 and BS7671.3
phase RCDs may also be tested if they have a neutral and
Loop Testers: It imperative to test fixed wiring
installations in industrial, commercial and domestic premises.
These digital loop testers test phase-earth and phase-neutral
supply loops with direct readouts of the prospective short circuit
current and prospective earth fault current. RCDs with ratings
of 30mA or greater do not trip during measurements.
Oil Test Sets: Insulation oil in transformers are
an efficient coolant as well as have a high flash point and high
electric strength. However over a period of time the insulating
properties of this oil need to be verified as degradation sets
in due to oxidation, acids, water absorption resulting in change
in its electrical properties. Automatic and semi automatic oil
test sets test samples of the insulating oil at variable test
voltages as high as 100KV.
Low Resistance Ohmmeters: Low resistance measurements
for earth bonding, welded joints in switchgear and contact breakers,
busbar and cable joints, small transformer and motor winding resistance
etc. can be effectively done by these instruments. With auto current
reversal and a rugged package these battery powered instrument
are at ease at the field or in the lab.
Line Testing Equipment: Featuring Live Alert safety
voltage detectors to warn personnel of unexpected live voltages
by an alarm, these can be clipped to a belt or carried by the
user on the field. Also available are voltage detectors and phasing
sticks for use upto 36.5 KV, these provide visual or audible indication
of grounded or ungrounded ac systems. Cable Phasing meters for
measuring voltage, phase rotation and phase out cables when connected
to capacitive test points. Also available are ultrasonic leak
and corona detectors for preventive maintenance in plants and
utilities to locate arcing connections, faulty insulators etc.
