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.
GDJF-2007 Digital Partial Discharge Analyzer is widely used for detecting partial discharge of high voltage equipment such as power transformers, instrument transformer, HV circuit breaker, GIS, Zinc oxide surge arrester, power cable.
TEV and AE method is acknowledged and suitable technology to be used in online partial discharge detection.
The GD-610C remote ultrasonic partial discharge detector uses an ultrasonic spectrum probe (sensor) to collect ultrasonic signals and analyze the sound of signals to diagnose faults, it is a diagnosis device for the accident of the distribution line.
Gas-insulated metal-enclosed switches (GIS) and gas-insulated metal-enclosed transmission lines (GIL) are one of the most important devices in the power system. They have the dual tasks of control and protection.
GDCY-20B Programmable Automatic Impulse Voltage Tester is mainly based on TB/T 2653, GB/T 17627, GB/T 16927, GB14048, GB7251, GB/T 16935, IEC 61730, GB4706, GB3048, JB/T 7083 and other standard requirements.
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.
GDZG-S series is equipment of testing DC voltage and DC leakage current of water-cooled generator in the situation of water through, which completely overcome the problems of long blow water time, bottom water hard to dry, easy to cause arcing within the coil. The device is light, simple wiring, and easy to read. Polarization compensation voltage is output directly by the case.
