A primary injection test set is utilized to evaluate the performance and functionality of electrical protection devices by injecting a high current directly into the primary circuit. This type of testing is crucial for ensuring that protective devices operate correctly and reliably under fault conditions.

Key Components and Features:

• High Current Transformer

• Control Panel

• Test Leads and Connections

Available Rating : 500A to 3000A @ 5V

Applications:

• Circuit Breaker Testing: Verifies the operation and trip characteristics of circuit breakers to ensure they will function correctly during fault conditions.

• Relay Testing: Tests protective relays to confirm they correctly detect and respond to fault conditions.

System Commissioning and Maintenance: Used during the installation and routine maintenance of electrical systems to validate and verify protective devices.
