отношение затухания сигнала к ослаблению перекрестных помех
Параметр, определяющий уровень помех в кабельной четырехпроводной линии, в которой передача и прием осуществляется по разным парам проводов. В проводной связи термин ACR играет примерно такую ту же роль, как и отношение сигнал/шум (SNR) в радиосвязи, т.е. для надежной работы линии необходимо превышение уровня полезного сигнала над перекрестной помехой. Отношение ACR зависит от частоты и с ее увеличением падает (рис. А-9). Скорость снижения зависит от конструктивных параметров кабеля: диаметра проводников и изоляции, шага скрутки и др. Пороговое значение ACR для кабеля типа “витая пара” на максимальной рабочей частоте обычно составляет 2-4 дБ.

20 PFC types
виды коррекции коэффициента мощности
-There are 2 types of power factor correction: fixed or automatic.
Fixed power factor correction consists of inserting, in parallel on the network, a capacitor bank whose total power is provided by the assembly of capacitors of identical or different ratings. The bank is energized by a contactor that simultaneously supplies all the capacitors (a single step).
The inrush current peak, in the case of fixed correction, can reach 30 times the nominal current of the capacitor bank.
An automatic power factor correction system, on the other hand, consists of several capacitor banks of identical or different ratings (several steps), energized separately according to the value of the power factor to be corrected.
An electronic device automatically determines the power of the steps to be energized and activates the relevant contactors.
The inrush current peak, in the case of automatic correction, depends on the power of the steps already on duty, and can reach 100 times the nominal current of the step to be energized.

PFC Types
There are two types of Power Factor Correction - Passive PFC and Active PFC.
Passive PFC uses passive elements like a ferrite core inductor on the AC input. It is very easy to implement in existing power circuits although the power factor is low at 60-80%. The proper AC input voltage (115V or 230V) must also be chosen manually. In addition, significant EMI can still result with a 115V AC source. Of course, a 230V AC source will not have this problem!.
Active PFC, on the other hand, uses a switching regulator with active elements like an IC, FETs (Field Effect Transistors) and diodes to create an active PFC circuit. This circuit allows the power supply to achieve a power factor of up to 95%, significantly reduce harmonics and automatically adjusts the AC input voltage. This means you do not have to manually select the AC input voltage. It works with all voltages from 110V to 240V.
