The PSStech Open Phase Protection (OPP) system*
is installed in 23 nuclear power plants, protecting 39 units. The PSStech OPP system is the leader in the industry in open phase protection.
Why Choose the PSStech System?
The PSStech implementation of open phase detection allows for a fail-safe and redundant detection design.
This design includes neutral overcurrent protection, continuous monitoring of all major system components, and only requires monitoring of a change
in signal level. This results in drastically reducing the engineering manhours needed.
The PSStech system combines active and passive protection, and is the preferred method over passive only protection.
Due to the simple, minimally intrusive installation, this design requires minimal outage time and maintenance.
The PSStech OPP system incorporates a simple operator interface developed from field-proven technology.
This system is the only field-proven system without blind spots for any type of open phase condition, with or without a ground fault of any impedance.
PSStech OPP systems are protecting transformers in nearly 40% of operating nuclear power plants across the United States.
Each site represented has multiple systems. There are more than 100 PSStech systems installed to date.
OPP Preventative Maintenance Services
Normal wear and tear on equipment can result in lower operational efficiency and increased operational
costs. Preventive maintenance ensures optimal working conditions and conserves the life span of the equipment. A planned preventive maintenance can decrease
actual downtime caused by a breakdown or mis-operation. PSStech offers a Preventative Maintenance (PM) and Extended Warranty agreements.
