1.Verify the protective relay: Ensure that the relay responds accurately to fault conditions.

2.Test current transformer (CT): Simulate high current to verify CT performance.

3.Simulate fault conditions: Generate high current to simulate real-world fault scenarios.

4.Calibration: Provides a reliable method for calibrating protective equipment.

Improve system reliability: Ensure that the protection system is correctly activated in actual fault events.

1, Electrical equipment testing and maintenance
1. Electrical equipment and component testing:
Overload test: Test the operating capacity of electrical equipment under conditions exceeding the rated current, and evaluate its overload protection performance.
Temperature rise test: By using high current to heat up the equipment, measure the temperature rise of each part of the equipment to ensure its safety during normal operation.
Voltage withstand test: to test the insulation performance of electrical equipment under high voltage and high current, in order to prevent equipment failure or safety accidents caused by insulation damage.
Circuit breaker test: Test the cutting ability of the circuit breaker under overload current and short-circuit current, ensuring that it can quickly operate in the event of a power grid fault and protect the safety of the power grid.
Contactor and relay testing: Verify the operating characteristics and reliability of these control components under specified currents, ensuring the accuracy and stability of the control circuit.
2. Cable and busbar testing:
Test the bearing capacity and insulation performance of cables and busbars under overload current, and evaluate their operational safety and reliability.

2, Materials Research and Processing
1. Material conductivity testing:
In the fields of materials science and engineering, primary current injection testers can be used to test the conductivity of different materials, providing a basis for material selection and application.
2. Metal melting and welding:
Through electric heating, a high current generator can quickly heat and melt metal materials for processes such as metal casting and welding.

3, Research and Teaching
1. Research experiment:
In scientific research experiments in fields such as power electronics, electrical transmission, and electromagnetic fields, high current generators can be used to simulate actual working conditions and provide necessary experimental conditions for scientific research.
2. Teaching demonstration:
In the teaching of electrical majors in universities and vocational colleges, primary current injection testers can be used for teaching demonstrations and experimental operations, helping students intuitively understand the principles of current generation, transmission, and control.

4, Industrial Automation and Other Applications
1. Industrial automation:
In industrial applications such as motor testing and control, electroplating, and electrolysis, primary current injection testers can be used to provide the required current output, ensuring smooth production processes.
2. Power system simulation and fault analysis:
By simulating various fault scenarios in the power system, such as short circuits, ground faults, etc., primary current injection testers can be used to evaluate the stability and disturbance resistance of the power system, providing important references for the operation and maintenance of the power system.
3. Other special applications:
In some special occasions, such as electromagnetic compatibility and interference testing, power electronic device testing, etc., high current generators can also play an important role.
