Voting, regarding overspeed protection systems, can be defined by the number of safety loops that should switch to the safe state when an overspeed situation is detected. The desirable voting…
Overspeed protection systems have a critical function in the balance between the safety and availability of rotating machinery. These protection systems should be proof-tested periodically to verify the system logic…
February 2021 marked the global launch of Istec’s revolutionary SIL rated overspeed protection system: the SpeedSys 200. The system is highly adapted to growing market demands and challenges overly complex…
The leading standard for rotating machinery (API 670) states that (critical) rotating machinery requires a state-of-the-art overspeed protection system. The availability of electrical overspeed protection systems has grown ever since…
Overspeed protection systems have one of the most important functions regarding safety measures for rotating machinery. As such, these systems require advanced safety functions to detect overspeed and excessive acceleration…
To measure the rotational speed of a shaft, it is necessary to have the right target for the contactless-sensing speed sensors to be able to generate an accurate signal. In…
There are several overspeed detection systems (ODS) on the market that are equipped with an on-board function generator for online test purposes, and this feature is frequently found in ODS…
Distributed control systems have been part of the automation of processes in a large scale of production plants for decades. These systems found their way into a wide range of…
End-users that operate (critical) rotating machinery have a legal obligation to implement a suitable and verifiable safety instrumented system (SIS). Safety Integrity Level (SIL, IEC 61508), one of the more…
In the past, overspeed turbine protection systems were often designed by the turbine OEMs themselves as part of the mechanical system. These mechanical protection systems are still in use, especially…
The API Standard 670 is an industry standard and describes the minimum requirements for a machine protection system (MPS). This includes, measuring radial shaft vibration, casing vibration, axial shaft position,…
