TESTING EQUIPMENTS
Protective Relay and Substation Tester
Brand: Teldar Instruments Co. IRT 660, Megger Sverker 900
Applications: Instrument designed for testing of electrical equipment eg. protective relay systems in substations and industrial plants. Can measure external voltages and currents and properties like level, phase, power factor and frequency.
SF6 Gas Analyzer Tester
Brand: Huazheng HZSF-41
Applications: Mainly used for Leak Detection about SF6 Gas related products or equipments such as GIS Switchgear, SF6 Circuit Breakers and other SF6 related electrical equipment.
Vacuum Bottle Circuit Breaker Tester
Brand: Huazheng HZ-KG7
Applications: Can measure the internal gas pressure of vacuum interrupter arc chamber. It will also test whether the vacuum tube has already deteriorated with the method of frequency withstand voltage.
Very Low Frequency (VLF) AC Hipot Tester
Brand: Huazheng HZDP-80kV
Applications: Can measure Medium-Voltage Power cables using AC Withstand Voltage Test to test the leakage current of the insulation at very low frequencies. It can effectively find more dangerous concentrated defects. It is the most direct method to identify the insulation strength of the electrical equipment.
Sweep Frequency Response Analyzer
Brand: Huazheng HZ-600A
Applications: Because electrical equipment such as Power Transformers are inevitably vulnerable to impulse of various fault short-circuit current or physical collision at the process of operation or transportation, winding may lose stability. It can measure the deformation of transformer windings using frequency response analysis.
Transformer Short-Circuit Impedance Tester
Brand: Huazheng TRZ-10
Applications: Can measure the short-circuit impedance value of the transformer. The amount of change in the short-circuit reactance is an important basis to determine the winding deformation of the tested unit.
