FUNCTIONAL SAFETY – SIL Electric actuators for safety-related systems up to SIL 3. Search. Note 2 : Lusser’s Law of Reliability states that the total reliability of a system dependent on the function of several independent components is the mathematical product of those components’ individual reliabilities. As mentioned before, the main idea of the “SIL classification analysis” is to specify a required SIL for each Safety Instrumented Function (SIF). The SIL (safety integrity level) concept was introduced in the HSE (Health and Safety Executive) PES (programmable electronic system) guidelines and subsequently extended in the development of IEC 61508. This PFD value incorporates failure probabilities of the sensor(s), logic solver, final control element(s), and the process piping including the reactor vessel itself plus any relief valves and other auxiliary equipment. Notify me of new comments via email. Two-wire transmitter are supplied directly by the supply unit to EExib (area 1) or EExia (area 0). If there arises a need to improve the PFD of this reactor’s over-pressure protection, safety engineers have a variety of options at their disposal for doing so.

Electrical Formulas helps us to calculate the parameters related to electricals in any electrical components.. For most safety functions in a train, SIL-1 or SIL-2 will provide acceptable risk levels. In reality, the SIL value of any safety function is a much more complex determination. Stability Limitation. Safety integrity level ( SIL) is defined as a relative levels of risk-reduction provided by a safety function, or to specify a target level of risk reduction. The comprehensive signaling with analogue, digital, and relay contacts provides preventive function monitoring. The SIL rating refers to the reliability of a safety function, not to individual components of a system nor to the entire process itself.

This can be used for the comparison of loads that can be carried on the transmission lines at different voltages, From the above expression power transmitted through a long transmission lines can be either increased by increasing the value of the receiving end line voltage (V, By applying some methods such as introducing series capacitors (capacitors in series with the transmission line) or shunt capacitors (capacitors in parallel with transmission lines) can be used to reduce the value of surge impedance (Z, Surge Impedance Loading (SIL) can be increased by reducing the Surge impedance of the line. A common way of ranking the dependability of a Safety Instrumented Function (SIF) is to use a simple numerical scale from one to four, with four being extremely dependable and one being only moderately dependable: The Required Safety Availability (RSA) value is synonymous with dependability: the probability (Note 1) that a Safety Instrumented Function will perform its duty when faced with a dangerous process condition. This is defined as the load (of unity power factor) that can be delivered by the line of negligible resistance. Adding to this confusion is the fact that many instrument manufacturers rate their products as approved for use in certain SIL-rated applications.

This is why a safety function may utilize a pressure transmitter rated for use in SIL-3 applications, but exhibit a much lower total SIL rating due to the use of an ordinary final control element. These software tools not only factor in the inherent reliability ratings of different system components, but also correct for preventive maintenance schedules and proof testing intervals so the user may determine the proper maintenance attention required to achieve a given SIL rating. For systems that are operating continuously, SIL and PL are both defined as ranges of the probability of dangerous failure per hour and they overlap. Safety Integrity Level.
