Primary Injection Test Set (Current Injector) About

Primary Injection Test Set (Current Injector)

Primary Injection Test Sets useable for Protective devices such as relays, overload Coils, Circuit breakers and CTs etc. must be checked regularly to ensure that they are always ready to operate correctly, Routine current injection testing will quickly detect faulty or incorrectly adjusted protection circuits / devices & will be possible to prevent serious damage to the system. Primary injection kit is designed to operate on single phase 230 Volts as well Two Phase 415V AC 50 HZ to develop smooth & continuous test current as for loading, calibrating, and testing of CTs, Bimetal Relays, Protection Relays etc. The test set gives high current output at low cost and with inherent safety .

Secondary injection testing is undoubtedly valuable, but it does not check all of the components in the system. the heating effect of the primary current will not be present and, in some types of test, this can significantly affect the results obtained.

FAQs of Primary Injection Test Set (Current Injector):

Q: How do I adjust the primary current during testing with this device?

A: The set features a rotary dial that allows users to smoothly vary the primary current. This lets testers accurately set the current to the required level for evaluating switchgear, circuit breakers, or CTs.

Q: What safety measures are incorporated into the Primary Injection Test Set?

A: To protect users, the device includes a built-in safety interlock and replaceable fuses. These features, combined with forced-air cooling, ensure safe operation during prolonged testing.

Q: When is the programmable test duration timer useful?

A: The programmable timer is beneficial for precisely controlling the duration of tests. This is especially important for verifying devices under conditions that replicate real-world scenarios, helping prevent overheating and ensuring repeatable results.

Q: Where can this test set be deployed effectively?

A: Its compact and rugged design makes it ideal for both laboratory and on-site applications. It is particularly suitable for use by maintenance teams, manufacturers, and quality assurance inspectors dealing with switchgear and protection equipment.

Q: What process should be followed for setup and operation?

A: Ensure the device is on a stable surface near a 230V AC supply. Connect the test leads as specified in the manual, adjust the current via the rotary dial, and set the desired test duration. The built-in fan and safety interlock will maintain safe operating conditions throughout the process.

Q: How does the set benefit circuit breaker and transformer testing?

A: By delivering precise, controlled currents, the test set facilitates reliable assessment of protective device performance. This helps identify faults or weaknesses before deployment, enhancing system reliability and safety.
