Version 2.1.1 of Invensys Operations Management’s Triconex Trident safety system is ready to go. The new version has two new input modules that enhance worker safety, reduce downtime and deliver more accurate trip analysis in power and turbomachinery applications, helping customers to achieve safety excellence. One new module enables faster response to unsafe equipment conditions; another optimizes trip data analysis to prevent future upsets.
“Protecting rotating equipment from damage is critical to our customers’ operations, and the ability to provide highly accurate plant information helps determine the root cause of trips more effectively, as well as achieve safety excellence,” said Alejandro Fung, director of safety systems product management, Invensys Operations Management.
The faster response time is the result of an enhanced pulse input module, which measures speed, rate-of-speed change and the rate of acceleration of rotating equipment in milliseconds. This enables faster prediction of over-speed conditions, which can jeopardize personnel, interrupt operations and damage equipment.
The optimized trip analysis is the result of a new high-resolution digital input module, which monitors changes of state and sequence of events (SOE) and provides a timestamp resolution of one millisecond with an accuracy of one millisecond. Process trips generate information about the conditions that caused the shutdown. Reviewing and analyzing that data can be time consuming, so having SOE data with a one millisecond resolution can aid in determining the root cause of the shutdown.
Triconex’s Trident safety system uses triple modular redundant technology.
