Akin et saray high-grade relay test sets et manguusar ni na linear power amplifiers imbes ya lighter switching (class-D) amplifiers?

Say amplifier so manunan kabiangan na relay test set: say relay so mandesisyon ed waveform ya naawat to, kanian say inkamatua na satan a waveform so mandetermina no kasin napanmatalkan iray resulta na test. Saray linear amplifier et mamapawala na reference sine wave ya abeba so total harmonic distortion, lapud say output transistor et mankikimey ed linear region to - ya anggapoy switching ripple ya na-filter.

Sine-wave purity -saray linear stages et mangiiter na malinis ya 50/60 Hz sine wave ya walay daiset ya harmonic content, ya asingger ed waveform ya nanenengneng na relay ed real power system.

Say inkasusto ed abeban tuloy iran kuryente -say importantin mangibiig. Saray pickup test na sensitibon proteksion (alimbawa, saray earth-fault elements ya asingger ed 0.01 A) et mankaukolan na susto tan malet ya output ed milliampere level. Say pulse-width modulation na switching amplifier et magmaliw ya maingal tan magaspang ed ontan ya abeban amplitude, bangta say linear amplifier et mansiansian malinis tan susto.

Say inkapekder ed silong na karga -saray linear ya desinyo et makatepel ed saray atagey ya inductive loads na relay trip coils tan current circuits ya anggapoy oscillation odino proteksion ya trip-outs ya nayarin ipatnag na saray desinyo na switching.

Say trade-off -saray linear amplifier et mas ambelat tan aliwan tanton epektibo; saray switching amplifier et melag tan epektibo ed enerhiya balet ta nababalang so waveform purity tan low-current precision. Parad proteksion ya panagsukimat, say inkasusto et mas baleg nen say belat.
