In the power system and equipment manufacturing industry, this tester is primarily used for dielectric strength verification and power frequency withstand voltage testing of electrical equipment.
High Voltage Tester is suitable for power frequency AC withstand voltage testing of equipment such as GIS, transformers, cables, and switchgear, ensuring insulation safety under high voltage operating conditions. Its stable output, comprehensive protection, and portable design are key advantages for power testing companies.
In substation automation systems, this tester is primarily used to verify the operating characteristics and logic settings of relay protection devices.
Protection Relay Tester simulates various fault waveforms to fully automatically test the coordinated operation of protection relays, current/voltage transformers, and circuit breakers. It supports differential, distance, and overcurrent protection types, making it an indispensable tool for power grid operation and maintenance and relay protection project commissioning.
During the commissioning phase of large electrical equipment, this equipment is primarily used to verify current transformer ratios, protection settings, and secondary circuit response.
Primary current injection equipment can output high-amplitude currents for busbar protection testing, circuit breaker tripping and closing experiments, and CT circuit calibration. Its high output accuracy and continuous stability ensure authoritative and repeatable test results.
During the manufacturing and maintenance of medium and high voltage equipment, this equipment is primarily used to detect and locate early-stage partial discharge defects.
Partial discharge test equipment can monitor the partial discharge characteristics of cables, transformers, and transformers online or offline, providing early warning of insulation degradation trends. Its key advantages include high sensitivity, strong interference immunity, and data traceability, helping customers implement refined operation and maintenance strategies.
In power plants and substations, it is primarily used to analyze circuit breaker operating time, synchronization, and mechanical characteristics.
The circuit breaker analyzer collects opening and closing times, speeds, current curves, and bounce parameters to assess whether circuit breakers meet technical standards for breaking capacity and response speed. It is a critical tool for ensuring safe power operation and is widely used in scheduled inspections and equipment acceptance.
In oil-immersed transformers and high-voltage transformer systems, it is primarily used to test the dielectric strength, moisture content, and dissipation factor of insulating oil.
The transformer oil test kit provides breakdown voltage, moisture content, acid value, and chromatographic analysis of the oil, helping users determine the extent of insulation degradation and maintenance requirements. Its modular design allows for flexible use in the laboratory and field, meeting diverse testing needs.
Used in UPS systems, power plant DC systems, and energy storage equipment, it primarily tests battery capacity, measures internal resistance, and assesses health status.
The Battery Test Kit automatically collects and analyzes data from both individual cells and entire battery packs. It can detect issues such as voltage imbalance, capacity drop, and abnormal internal resistance, helping customers proactively identify battery degradation risks and improve the stability and availability of power supply systems.
