Schneider Nulec TTS

The Schneider NuLeC Test and Training Set (TTS) is a sophisticated interface device designed to connect the switchgear’s ADVC controller with a secondary injection test set. This powerful tool enables users to verify and fine-tune the current protection parameters of the controller efficiently.

The TTS facilitates secondary current injection testing through connections with either the control cubicle’s 24-pin port or the current injection port (CIP) of the ADVC controller. It is versatile enough to perform both single and multi-phase secondary current injection, ensuring comprehensive testing capabilities.

Additionally, the TTS functions seamlessly in conjunction with the Secondary Voltage Injection Interface Set (SVIIS) for enhanced secondary injection testing, catering to ADVC-based NuLeC reclosers and sectionalisers across various series such as N-, U-, RL- and W-Series.

• Allows single or multi-phase current injection during tests.
• Compatible with both standalone and parallel operation modes for control cubicles.
• Includes dry contacts to emulate switchgear operations, ensuring precise timing evaluation.
• Provides up to 110 VAC equivalent primary voltage, depending on calibration.
• Designed for compatibility with SVIIS, enabling current and voltage injection across all six bushings.

• Conduct robust testing of current protection parameters to maintain optimal system performance.
• Ensure greater precision with versatile single and multi-phase current injection options.
• Enhance operator confidence and competence through safe and effective training applications.
• Seamlessly integrate with the Secondary Voltage Injection Interface Set (SVIIS) for comprehensive system testing.

• Switchgear training — Ideal for training purposes, the TTS allows operators to practise and understand the operation of switchgear systems. It provides a safe environment to simulate real-world scenarios, enhancing the competency and confidence of the personnel handling these critical components.
• Parallel operation mode testing — In parallel operation mode, the Schneider Nulec TTS can be connected alongside the actual switchgear to the control cubicle. This setup enables comprehensive testing without interrupting service, ensuring both the TTS and the switchgear operate correctly under combined conditions.
• Standalone mode testing — In standalone mode, the TTS is connected to the control cubicle in place of the switchgear. This mode is essential for testing the control systems independently, verifying that all signals and responses are correctly managed by the control cubicle without the switchgear connected.
