Auto compensation stepped series reactor
Introduction
The reactive power compensation in electric power system widely adopts switchingon-off shunt capacitor banks as dynamic reactive power compensation device forlimiting flow. Each set of capacitor should be equipped with a set of seriesreactors with 6% reactance rate.
.
The equipment need large occupied area and high cost because each set ofcapacitors needs to be equipped with a set of series reactors. Reactors withtap can replace the original multi-bank series reactor to reduce neededoccupied area and save cost. Taking three sets of “On-off” capacitors as anexample: if one set of series reactors with tap is used to replace the originalthree sets, it has to work with a no-load switch for switching which causeon-line regulating become impossible.
The new type automatic compensation stepped series reactor takes place ofthe original series reactor with taps and can be connected with 2 sets of capacitorbank. This reduces the number and the occupied area of series reactor and alsorealizes automatic grouping “On-off” of capacitor under working condition. Integratedautomation of substation also becomes possible. It is a reactive compensation renewalproduct of substation for grid voltage improving.
Application
The product is mainly used in power system and work together with groupingon-off capacitor banks to form a dynamic reactive compensation device. It has advantagesof small occupied are, low cost, energy saving, and widely use in power system.The product realizes the integrated control of voltage reactive-power ofsubstation. It also ensures power supply voltage quality and power factorrequirement. All these features achievethe goal of reducing energy loss, decreasing voltage fluctuation and improvingequipment utilization.

- Q: Do they design circets for the electricity? If not, what do they design?
- There are many different areas of specialization in electrical engineering.
- Q: I haven't worked in this field in the UK, although I am able to diagnose problems, service and repair electrical equipment.
- Go to the local unemployment office, put a notice up on store bulletin boards one at the postoffice if allowed. Put add in paper. Make sure you aren't breaking the rules and regulations of the country you want to work in but then you can find that out when you go to employment office. Go to schools, see if they need your expertise, go to people building just on the new list and not quit finished yet. Good luck.
- Q: I have worked there as an electrical engineer but in design for a consultant. I would like to know what are the major things to account for (DB's, wires and cables, ducts, conduits.) and how to estimate them for a typical 6000sq.ft 2 floor villa
- If you have the design drawings, you simply have to make a material take-off list. The main drawings are: General Layout Grounding Layout Electrical Equipment Layout / Schematic Riser Diagram (Fire Alarm) Lighting Layout At the very least, you need to have the General Layout drawings (to know how many rooms you've got) and you need to know the electrical levels since some houses might require 380/480 3-phase for elevators and large electrical equipment. Working room by room, you will estimate cable and conduit lengths, the number and specifications of the DBs, number of lights, outlets, switches, buzzers, intercoms, smoke detectors.
- Q: considering that he is specialised in power engineering or does he administers them.
- Turbine engines (either steam of fuel-injected) are mechanical parts and not electrical parts. A electrical engineer will be working on the generator that is attached to this systems. They will also work on the transmission of that power (Transformers and all that good stuff!).
- Q: all electrical equipment goes dead in car. If disconnect battery, then again appears to have electrical power, no fuses in panel or battery relay blown, but ignition clicks once and all electrical out again in car and starter does not engage.
- Starter problem it sounds like. Starter solenoid more likely. Take a pry bar of some sort, place it on the starter solenoid if you can reach it, and tap on it while someone else turns the key. If that doesn't work, remove the starter, and replace it.
- Q: can i sell magnetic contactor transformer 24vand where ?
- With an accurate description and a couple of good pictures, you can sell just about anything on OKorder. Don
- Q: ???I recently went into a century tel building and was VERY interested. Does that have anything to do with what an electrical intrumentation technician does? If not please explain to me the difference between some one that is an electrical instrumentation technician would do, and what someone that works at century tel would do. I know this is a lot but Im planning for a major, and after that a career.Thanks!!!
- Ammeter,volt meter,power meter or watt meter,protective relays all these are electrical instruments. Technician repair,install,test, calibrate such equipments But instrument technician electrical is different.He repair, test calibrate pressure gauges, temperature gauges,Level gauges,Flow meters,Process control instruments all working on electrical priniple.
- Q: i am instrument electrical eng.student and i am about to take 2 of the 4 subject for electives, here the subject:1)process control2)automation and robotic3)measurement and instrumentation4)control system 3i am thinking to involve in maintainance,oil and gas or maybe aircraft maintainance.after grad.what is the subject is suitable and what is the subject advantage and disadvantage. i want get some advice before make the decision.tq
- Well. it is very good major Oil and Gas companies need ur major since the instrumentation is controlling the whole units. Huge Essential System and very critical in any refinery such as: DCS : Digital Control Center. ESD: Emergency Shutdown. UPS: Uninterrupted Power Supply ( Electrical Equipment feeds instrument load) I think u have a bright future with this discipline if you have interests . And regarding these Subjects, i dont know much about control All the best
- Q: I am just a few classes away from getting my Associates in Electrical Engineering. I currently have a Diploma in Industrial Electricity and have been working in industrial maintenance for 12 yrs. and am currently an electrical technician (10 yrs. multi-skilled and the last 2 yrs. strictly electrical due to a job change). I have returned to school to get my AAS in EE, so I would really like to know what possibilities I could expect.
- You can get a job as an electronic engineering technicians. You help design, develop, test, and manufacture electrical and electronic equipment such as communication equipment, medical monitoring devices, navigational equipment, and computers. You may work in product evaluation and testing, using measuring and diagnostic devices to adjust, test, and repair equipment. Median annual wages of wage and salary electrical and electronic engineering technicians were $53,240 in May 2008. The middle 50 percent earned between $41,550 and $64,120. The lowest 10 percent earned less than $32,490, and the highest 10 percent earned more than $78,560. Median annual earnings in the industries employing the largest numbers of electrical and electronic engineering technicians were:
- Q: Hi I have the chance to have a small premises at a garden center I would be allowed to advertise and was thinking of having a small studio thereI already have 2 home studio lights interfit background support and 3 backdrops I would be aiming to photography babies and childrendoes any one know what health and safety regulations i have to follow, what insurances is neededI already have equipment cover including my computer public liability and public indemnitydoes all equipment like the lights and backdrop have to be secured?do i have to have a credit card payment machine? basically i want to know every thingAndrea
- Disabled access. Public liability Insurance. Possibly a toilet and wash basin which should also be adapted for the disabled. Tea/coffee facilities. Certificate to say that you are allowed to carry out a business on the premises. (?) Certificate from from an electrician to say that the electricity supply is safe. Fire escape. Fire extinguishers. Certificate from the Fire brigade. Thats a start for you.
