Leading Passive Mechanical Fast Depressurization System for Transformers

The TRANSFORMER PROTECTOR (TP) is a passive mechanical system, activated by the First Dynamic Pressure Peak generated at the origin of any low impedance fault.

The TRANSFORMER PROTECTOR can be fitted on new and existing transformers from 0.1 MVA to 1,000 MVA and adove.

The TRANSFORMER PROTECTOR (TP) has several configurations of protection, which mainly depend on transformer design and customer technical specifications. SERGI Transformer Protector focuses on offering a performant, affordable and compatible solution in order to ease its implementation without interfering with the current transformer design.

The TRANSFORMER PROTECTOR ensures a reliable power supply. Our mechanical operation safeguards transformers from cyberattacks, contributing to energy grid resilience and robustness. Resilience involves withstanding disasters, while robustness adapts to changing energy sources.

Depressurizes tanks within milliseconds
Avoids contact between air (oxygen) and explosive and inflammable gases (e.g. Acetylene, Hydrogen, etc.) Separates gases from oil
Channels the flammable gases far away from the transformer to a remote area
Eliminates explosive and flammable gases trapped in the transformer by injecting an inert gas into the tank, to avoid the bazooka effect that could injure or kill technicians when opening tanks after a low impedance fault
Quickly brings the transformer to a safe condition for repair after a short-circuit

The TRANSFORMER PROTECTOR (TP) is a Fast Depressurization System as defined by the National Fire Protection Association (NFPA), NFPA Recommendation 850, 2020 edition.
