The deceleration time is another simple means of evaluating the MV area, in which decay of the mitral inflow profile through a stenotic MV is examined. The following formula describes the relationship of the deceleration time to the MV area (19):
Tripping classes of the thermal overload relays Standard classes in IEC 947-4-1 are classes: 10 A, 10, 20, 30. The tripping class indicates according to IEC 947-4-1 the maximum tripping time in seconds under speciï¬ ed conditions of test at 7.2 times the setting current and speciï¬ es tripping and non tripping times for 1.5 and 7.2 times the setting current. Mostly used class is 10 A. Abstract from IEC 947-4-1 Tripping class 10 A 10 20 30 Max. tripping time
