1 Electrical network is one kind of pipeline network, which provide a perfect base for applying GIS.

2 However, the electrical network environment pollution brings certain difficulties to the reliable communication.

3 The electrical network can be configured with a linear or tree topology.

4 Electrical network flashing will threaten the safe operation of gas expander - main blower set in FCC unit.

5 Accurate electrical network automatic compensation and overcurrent, overvoltage , undervoltage, overheating, etc protection functions make welding machine more safety and credibility.

6 In an electrical network, unbalanced and harmonic currents generated by nonlinear and unbalanced loads can cause harmonics and unbalanced voltage.

7 Key words: low current earth electrical network, transient earth fault, zero - sequence energy, energy variation.

8 A common method of analyzing an electrical network is mesh or loop analysis.

9 This paper introduces how to setup electrical network classroom by Netmeeting in three aspects.

10 The power plant has the pivotal function in the electrical network voltage adjustment.

11 By the invention of Inerter, the mechanical network can be analogous to the electrical network perfectly.

12 It is an objective and quantitative system approach to comprehensive construction scale evaluation of distribution network for district electrical network planning.

13 At the same time, combines to the transmission coefficient among different voltage classes, through a series of simulations, does researches on the flicker transmission rule in the electrical network.

14 High frequency channel as the signal transmission path of the carrier current protection is important to the safety of electrical network.

15 It is widespread in practice that three - phase asynchronous electrical machinery runs in one - phase electrical network.

16 KIWA synthetic power saver with his unique structure form eliminates higher harmonic of the electrical network by way of the balance in adjusting three-phase current and voltage .

17 Active Power Filter(APF) technology is one of the important ways to realize harmonic wave compensation of electrical network and improve the quality of power supply.
