PRAGATI PROCESS CONTROLS

The secondary protection system may comprise protective relays, auxiliary relays, protection circuits, communication and control systems, metering devices, low-voltage components, alarms, and more. Consequently, the secondary injection test not only assesses the protective relays and their trip settings but also verifies the functionality of all related circuits and devices essential for the effective operation of the secondary protection system.

Key Features:

• Continuously variable outputs
• Multi-range digital timer with time base
• True RMS digital measurement of outputs
• Automatic shut-off in all operational modes
• Fully isolated, distortion-free current outputs
• Capable of testing thermal devices

Secondary Current Injection Test Set

A Secondary Current Injection Test Set is a specialized tool used to verify the functionality and performance of protective relays and associated protection systems in electrical installations. This testing equipment ensures that protective devices operate correctly under fault conditions.

We manufacture Secondary Current Injection Test Sets in various designs to meet diverse needs, including:
