A capacitor draws leading current. When connected to an inductive circuit, it offsets its inductive (reactive)... [Pg.727]

Shunt capacitor - connected across the inductive circuit to improve its p.f. [Pg.727]

In an inductive circuit the presence of harmonics is not felt so much as the higher harmonics lend to enhance the harmonic reactance, which causes a dampening effect ... [Pg.734]

Where the inductive circuits equal the capacitive circuits, the apparent power coincides with the active power. Thus, the power factor for the system is 1.0, and all power is consumed usefully. [Pg.628]

Let s now consider an inductive circuit where application of voltage V produces current I as shown in Figure 6.2 and the phasor diagram for a single-phase circuit is as shown. The current is divided into active and reactive components, /P and /Q ... [Pg.143]

Another use for VDRs is the suppression of sparks in switches and relay contacts in highly inductive circuits, and it is instructive to outline the principle of operation. [Pg.154]

It is noteworthy for people busy in the field of electrical power engineering that ohmic-inductive circuits with L/R ratios <1 ms (even in the range L/R = 10 ps or L/R = 100 ps) are considered as inductive circuits in EN 50020. For comparison, in power circuits, contactors and motor starters for direct current application are rated for L/R ratios within a range 1 ms = L/R 15 ms... [Pg.20]
