Is capacitor reactance [sometimes] defined with negative sign?
$begingroup$ If you look at a reactance of an element (disregard what kind of element it is), if the value is negative, that element would be considered capacitive, and if the value is positive, the element would be considered inductive. If you''re specifically talking about a capacitor, you can assume it''s a capacitive device, and it''s reactance is guaranteed to …

Capacitive Load: Concepts For PFC And Voltage Regulation.
A capacitive load (CL) plays a vital role in the performance and efficiency of electrical systems. By understanding its characteristics, impacts on power factor and voltage regulation, and the role of capacitor banks in managing it, engineers and technicians can optimize electrical systems for maximum performance and stability.
Inductors in Series. If two inductors are placed in series, each will produce an induced EMF, and the total induced EMF will be increased. The opposition to current flow is therefore increased. By placing inductors in a series, the total inductive reactance increases in the same way that placing resistors in a series increases the total resistance:
Learn about the fundamentals of inductors in AC circuits, including the concept of inductive reactance, the behavior of inductors in series and parallel configurations, and how power is influenced in inductive circuits. In AC circuits, inductance plays a fundamental role
Is capacitor reactance [sometimes] defined with negative sign?

Principles of Shunt Capacitor Bank Application and Protection
2 capacitor bank. These parallel groups are then connected in series to meet the nameplate voltage rating of the capacitor units. Capacitor units are available over a wide voltage range (216 V to 24,940 V), and VAR …
What''s the Role of Shunt Capacitor in Electrical Distribution
Using several units rather than one creates a reliable reactance against recurring inductive reactance. This group of capacitor units is referred to as a capacitor bank . Capacitor banks are common within power substation or systems that supply energy to businesses and residents within a particular region.
Capacitors units are intended to be operated at or below their rated voltage and frequency.. IEEE Std. 18-1992 and Std 1036-1992 specifies the standard ratings of the capacitors designed for shunt connection to ac systems …
The pure inductive loaded system and phasor diagram are illustrated in Fig. 8.3 referring to aforementioned approach. The pure inductive loads, i.e. shunt reactors used in tap-changing transformers and generation stations, do not draw power and δ between load voltage V and source voltage E is zero. Since the voltage drop jX S I is in phase …
