Partial stroke testing (or PST) is a technique used in a control system to allow the user to test a percentage of the possible failure modes of a shut down valve without the need to physically close the valve PST is used to assist in determining that the safety function will operate on demand PST is most often used on high integrity emergency shutdown valves (ESDVs) in applications where
Cyndi Nyberg Former EASA Technical Support Specialist In the April 2007 issue of CURRENTS we covered surge testing anomalies speci cally for AC windings The surge test can be used for DC windings as well It can be a useful tool for evaluating armatures and some DC fields A note of caution: If a winding does not have a minimum insulation resistance per ANSI/EASA AR100-2006 it is not
