GDWR-5A Earth Resistance Tester is a high-precision test instrument used in various fields such as substations for testing grounding resistance and related parameters. The instrument has the characteristics of small volume, light weight, convenient carrying, strong anti-interference performance and high accuracy.
According to IEC and the relevant national standards, transformer turns ratio test is a necessary project in the process of power transformer production, user handover and maintenance test.
GDJR-200D Single Phase Electronic Thermal Relay Calibrator is mainly used for the setting and verification of various electrical equipment. With features of reasonable design, convenient operation and large output power, it is widely used in electric test sites of power system, railway, petrochemical, metallurgy and mining enterprises.
GD8000C quantitatively leak online monitoring system is mainly used in the 35KV SF6 switch room and 500KV, 220KV, 110KV GIS room in the substation to monitor the SF6 gas leakage in the SF6 combined electrical equipment room environment and the oxygen content in the air in real time.
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.
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.
