Product Advantages

Accurate Mechanical Performance Analysis
The HY Series tester provides precise measurements of breaker operating time, operating speed, and contact resistance, helping maintenance engineers assess the mechanical and electrical condition of high-voltage circuit breakers.

Reliable Contact Resistance Testing
The high-current test function allows engineers to detect abnormal contact resistance and conductive-path problems, supporting preventive maintenance and fault diagnosis.

Efficient Field Testing
The integrated test platform reduces the need for multiple instruments during circuit breaker commissioning and maintenance, improving testing efficiency at substations and power plants.

Portable & Rugged
The compact protective case provides convenient transportation and protection for field applications, making the tester suitable for demanding electrical testing environments.

Digital Measurement & Data Management
Measurement results can be displayed, stored, reviewed, and printed directly, helping users create standardized test records for equipment commissioning and maintenance.

Flexible Configuration
The standard 8 m test cable provides sufficient flexibility for many on-site applications, while cable length can be customized for specific testing environments.
