Product Overview
The YDJ Series Power Frequency High Voltage Withstand Voltage Test Equipment is developed for high-voltage insulation testing of transformers, switchgear, cables, insulators, and other electrical products.
The system generates adjustable high-voltage output through a dedicated control unit and a high-voltage test transformer. It allows operators to apply specified test voltages to electrical equipment and evaluate its dielectric withstand performance under controlled testing conditions.
Highlight
1. Adaptable to Different Testing Environments
Electrical manufacturers and testing laboratories often work with different types of test objects. Their requirements for voltage, capacity, insulation structure, and operation methods are not always the same.
2. The YDJ Series offers several configuration options:
Multiple High-Voltage Generation Structures
Choose from SF6 gas-insulated, oil-immersed, epoxy resin dry-type, and other available transformer structures.
3. Different Control Technologies
Manual, electric, fully automatic, and industrial computer-controlled operation options are available.
4. Single-Stage and Cascade Configurations
The equipment can be configured for different output voltage levels, including higher-voltage applications using cascade transformer arrangements.
5. AC/DC Testing Options
AC and AC/DC dual-purpose configurations are available according to the selected transformer model.
6. Optional Digital Functions
Depending on the control unit, the system can support digital measurement, USB communication, computer operation, data storage, and report printing.
Typical Testing Applications
FAQ
Q1: What is a power-frequency withstand voltage test?
A: It is a dielectric test in which a specified AC voltage at power frequency is applied to the insulation of electrical equipment for a prescribed duration. The purpose is to evaluate whether the insulation can withstand the specified electrical stress.
Q2: What types of electrical equipment can be tested?
A: Typical applications include power transformers, switchgear, circuit breakers, cables, insulators, bushings, motors, and other electrical components. The suitability depends on the required testing method and equipment configuration.
Q3: What is the difference between a high-voltage test transformer and a complete hipot test set?
A: A test transformer generates the high-voltage output, while a complete hipot test set also includes the control unit and associated components required for operating and controlling the test process.
Q4: Which transformer structure should I choose?
A: YDQ(Z) uses SF6 gas insulation, YDJ(Z) uses insulating oil, and GTB(Z) uses epoxy resin dry-type insulation. The choice should be based on voltage requirements, capacity, installation environment, and application.
