Primary Current Injection Test Equipment Strong Current Generator
In order to ensure the safety and reliability of electrical systems, it is essential to test the performance of protection devices such as circuit breakers, relays, and fuses. These devices are designed to detect and isolate faults or overloads in the electrical system, but they must be tested regularly to ensure that they will function properly when needed.
This is where a Primary Current Injection Tester comes in. It is a specialized instrument that is specifically designed to test the performance of these protection devices by injecting a high current into the primary circuit. By measuring the resulting voltage drop and other parameters, the Primary Current Injection Tester can determine whether the protection device is functioning correctly and providing the necessary level of protection.
Without a Primary Current Injection Tester, it would be difficult to verify the performance of these protection devices, and the safety and reliability of electrical systems could be compromised. Therefore, the importance of this instrument cannot be overstated in the field of electrical testing and maintenance.
Test Procedure
1. Preparation: Before beginning the test, the technician must ensure that the equipment is properly set up and that all safety precautions have been taken. This includes making sure that the equipment is grounded and that appropriate personal protective equipment (PPE) is worn.
2. Connection: The Primary Current Injection Tester is then connected to the primary circuit of the protection device under test. The connections must be made in accordance with the manufacturer's instructions and any applicable safety standards.
3. Injection: The tester generates a high current that is injected into the primary circuit of the protection device. The current is typically ramped up gradually to avoid damage to the device or the test equipment.
4. Measurement: As the current is injected, the tester measures the voltage drop and other parameters to determine the performance of the protection device. This may include measurements of the trip time, trip current, and other relevant parameters.
5. Evaluation: Based on the measurements, the technician can evaluate the performance of the protection device and determine whether it meets the required specifications and standards. If the device fails the test, it may need to be repaired or replaced.
6. Documentation: Finally, the results of the test are documented, including the test parameters, measurements, and any necessary corrective actions. This documentation is important for record-keeping and future reference.
Pay attention to the following points when selecting:
1. Working power supply: AC220V or AC400V, 45Hz~65Hz, the working voltage is different and the power input capacity is different.
2. Rare input current: 500A or 1000A or 2000A.
Rare input capacity: 3KVA or 5KVA or 10KVA or 15KVA.
