Elemen data presentation Data Presentation Gb 13.1 Klasifikasi elemen data presentation
A record would be require: (a)a high speed event (b)large amount of data (c)in fault situation Pointer scale indicator: T D = B n A i T R = c i = E TH - E b R TH + R L
6 E b dapat dihitung dengan Faraday`s law: E b = n AB K = steady state sensitivity w = frequency natural = damping ratio dd dtdt E TH (s) = K 1 wn2wn2 s wnwn s +1
7 Gb 13.2 Pointer scale indicator
8 Galvanometer recorder Sensitivity steady state dari recorder: y y E TH = Gb 13.3 uv. galvanometer recorder
9 Servo recorder Gb 13.4 servo recorder
10 y E TH = K D K A K I LIs 3 + [R 1 +L(K V +b)]s 2 +R(K V +b)s + K T K A K I Digital recorder -qualitative analysis of high speed event -quantitative analysis can be performed -interpolation -digital strip pointer
