AC hi-pot testing is the effective and direct way to test insulation strength for electrical equipment, apparatus or machines. It checks dangerous flaws which assure electrical equipment continuous working.
GIT series is widely used for high voltage, big capacity GIS power equipment insulated withstand voltage test, partial discharge test and GIS transformer accuracy test, suitable for GIS substation, GIS power equipment manufacturer, basin type electrical insulator manufacturer.
It widely used in electrical manufacturing, power operation departments, research institutes and universities.
Withstand voltage test is an essential preventive test for electrical equipment. It is divided into two parts: AC and DC withstand voltage test.
GDFR-C1 series AC/DC digital meter is on-site instrument, which test both AC and DC voltage. It consists of voltage divider and measurement instrument.
GDFR-D1 Series AC/DC digital meter is on-site instrument, which test both AC and DC voltage. The digital meter and divider are equipped in one unit.
GDZJ-5S is used to test turn-to-turn insulation strength of single-phase motor, 3-phase motor, Micro motor, Special motor, electrical motor, transformer (including switching mode power supply transformer), relay and winding electrical equipment.
GDZJ-30S is used to test turn-to-turn insulation strength of rate voltage 10kV motor, HV and LV motor, AC/DC motor, transformer winding and coil winding.
GDTL AC Resonant Test System for CVT is series resonance with power frequency specially for CVT.
GDTL series AC Resonant Test System for Generators can be used by adjusting inductance of the reactor, or adjusting the work way of resonant frequency of the system to achieve resonance.
GDTF Series AC Resonant Test System For Cables are composed of frequency/voltage adjustment power supply, excitation transformer, reactors and capacitive divider.The power frequency can be adjustable, which make the reactor and tested capacitor resonance.
