Operation Steps

Primary Current Injection Testers work by injecting a high-current test signal directly into electrical protection devices to test their performance. Here are the general steps involved in the operation of a Primary Current Injection Tester:

1. Set up the equipment: Set up the Primary Current Injection Tester according to the manufacturer's instructions, ensuring that it is properly grounded, and all cables and connections are secure.

2. Connect the test equipment: Connect the output of the Primary Current Injection Tester to the device under test, making sure to follow the manufacturer's instructions for the proper connection.

3. Set the test parameters: Set the test parameters, such as the test current and duration, according to the manufacturer's instructions and the requirements of the testing standard.

4. Perform the test: Apply the test current to the device under test and observe the device's response. The Primary Current Injection Tester will measure parameters such as trip time, trip current, and other relevant parameters, to determine the performance of the protective device.

5. Record the results: Record the test results, including the measured parameters and any other relevant information, such as the ambient temperature and the impedance of the device under test.

6. Analyze the results: Analyze the test results to determine if the device under test meets the required performance specifications.

7. Troubleshoot and repeat: If the device under test fails the test, troubleshoot the issue and repeat the test as necessary until the device meets the required performance specifications.

It is important to follow the manufacturer's instructions and the requirements of the testing standard when operating a Primary Current Injection Tester. Additionally, proper electrical safety precautions, such as wearing appropriate personal protective equipment and ensuring that the equipment is properly grounded, should be taken to prevent injury or damage to equipment.

What is primary and secondary injection testing:
Primary and secondary injection testing are two different methods used to test the protective relays and circuit breakers of electrical systems.

Primary injection testing involves injecting a high current directly into the primary side of the protective relay, simulating a fault condition in the electrical system. This method is used to test the entire protective relay system, including the current transformer, wiring, and associated protective equipment. Primary injection testing is typically used for testing high-current applications, such as power transformers and generators.
Secondary injection testing, on the other hand, involves injecting a low-level current into the secondary side of the protective relay, simulating a fault condition. This method is used to test the relay's internal components, such as the trip unit and wiring, and to verify the relay's settings and response time. Secondary injection testing is typically used for testing low-current applications, such as motor control centers and switchgear.
