EUROSAFE Nitrogen Injection Transformer Protection System 11

Nitrogen Injection Fire Protection System (NIFPS) for Transformers

A Nitrogen Injection Transformer Protection System is an advanced method of safeguarding power transformers from hazards such as fire, explosions, and damage caused by electrical faults. This system utilizes nitrogen gas to create a controlled and inert environment within the transformer’s oil-filled tank. The primary purpose of this injection is to suppress the potential for oxidation, combustion, and the release of flammable gases that can lead to dangerous incidents. It’s Designed as per NFPA Standard.

NITPS SYSTEM DESCRIPTION

Our Unique Nitrogen Injection Transformer Protection System looks after the health of your Transformer and guards it against any potential internal or external fires. Transformers can experience internal fires due to arcing, dielectric breakdowns in the core and coils, twists in the winding, not enough grounding- the list goes on. External fires can be caused by issues with the OLTC, oil leaks from gaskets, faulty welding cords, forced cooling fans that are malfunctioning, faulty Buchholz Relays, current transformer problems at the bushings, or busted bushings, improper/loose cable connections, or even transmission line faults.

SYSTEM DETECTION

Detecting any rise in temperature is essential, and our Hollow-Metallic Tube Linear Heat Detection System does just that! It can pick up on fire or heat at an incipient stage and will generate a command to activate the extinguishing system. This system is filled with ambient air and evaluates pressure from the rate of two samples per second. It will trigger the Transformer if the temperature gets too high, which can be programmed to be much lower than the flashpoint of oil – helping to avoid any tank rupture or fire if internal or external faults occur. This detection unit is UL, FM & VdS approved.

The Nitrogen Injection Fire Protection System (NIFPS) works to prevent tank explosion or rapture and possible oil fires due to minor arcing from internal or external sources. The PLC-based NIFPS will receive Feedback/Trip Signals from the Transformer Panel if temperatures rise beyond what’s allowed. Upon detecting this, it triggers electrically operated elements like Isolation Valves, Oil Drain Valves, and Nitrogen Injection Valves to create a layer of rest oil over all other oil and prevent contact with oxygen from the atmosphere. Steel cage ball valves permit a complete opening for evacuation of oil away from the system, and all these actions can be done manually too. On top of that, our Microprocessor/PLC based System also offers SCADA graphical representation of faults for easy interfacing with main control panels.

OPTIONAL FEATURES

Our unique External Fire Suppression System can suppress any fire and minimize any further damage by cooling the system. It includes a Water Mist Fire Suppression feature, a High Velocity Water Spray System and Compressed Air Foam System (CAFS). Additionally, it features state-of-the-art heat/fire temperature sensors with a temperature range of -40oC to +160oC, an auto and manual extinguishing system accessible from both the field and control room, a total length of extruded metallic detector ranging from 15 to 115 meters, the ability to record up to 16 million events with an installed SD card, and detection systems that are UL, VdS and FM approved. Lastly, the system is PLC/microprocessor based and interfaced with SCADA integration for automatic self-diagnostics for its self-health check-up.

Nitrogen Injection Transformer Protection Systems(NIFPS) are particularly valuable in critical infrastructure settings, such as power substations and industrial facilities, where transformers are central to operations. By proactively mitigating the risks associated with transformer failures, fires, and explosions, this system enhances overall safety, minimizes downtime, and safeguards against potentially catastrophic incidents.
