- Q: Two different impedance of the transformer, parallel load how to allocate?
- When the impedance voltage is equal, the transformer runs side by side: Because the transformer load distribution is proportional to its rated capacity, and inversely proportional to the impedance voltage. In other words, when the transformer is running in parallel, if the impedance voltage is different, the load is not proportional to the rated capacity of the distribution, parallel transformer current and impedance voltage is inversely proportional to the II / III = UZKII / UZKII or UZKIIII = UZKIIIII, Set two transformers running side by side, the capacity of SNI, SNII, impedance voltage UZI, UZII, then the load of each transformer according to the following formula: SI = [(SNI + SNII) / (SNI / UZKI + SNII / UZKII)] * (SNI / UZKI) SII = [(SNI + SNII) / (SNI / UZKI + SNII / UZKII)] * (SNII / UZKII) That is, S △ I / SII = (SNI * UZKII) / (SNII * UZKI) According to the above analysis we can see: When two transformers with different impedance voltage are running side by side, the distribution load with large impedance voltage is small. When this transformer is full load, another transformer with small impedance voltage will run over load. Transformer long-term overload operation is not allowed, therefore, only the impedance of the transformer voltage overload operation, thus limiting the total output power, energy loss also increased, it can not guarantee the economic operation of the transformer. Therefore, in order to avoid the impedance voltage difference is too large, so that the parallel transformer load current distribution is uneven, affecting the transformer capacity can not be fully played, the specified impedance voltage can not be a difference of 10%.
- Q: 1.Is there going to be a Season 4?2.If there isn't,then is there going to be a new Transformers series?
- That would suck sooooo bad if it is cancelled. All that build up in the first season with super villains and no Megatron and like, 3 Decepticons till the end of season 2 for what! To take it all away just as its getting good and finally setting up a full on Autobot Decepticon war There better be a season 4 or this series will go in the forgotten bin with Robots in Disguise as another series that took forever to set just for 1 big battle then that's the end. But if it is the end then that will teach the writers for holding out on what fans really want. I can not sit through season 1 or 2 again, except the season 2 finale.
- Q: I need this Radio Shack transformer to provide power to a HO scale model train board lighting system. This transformer will be connected to a brightness control system and then the brightness control system will be connected to building lights and street lights. I have been told this issue is a safety and Electrical Code concern?
- a acceptable web site. Face the construction south with residing house windows in basic terms in the south elevation. the north elevation could the two have a small variety of small residing house windows or be breamed with earth. For an present residing house, Geothermal is huge in case you have the money. the traditional forced warm air gadget that maximum US properties has is likely considered one of the main effective for the preliminary value and maintenance in comparison to the warmth is generates. A German business enterprise, called viessman (sp) creates very useful structures for this configuataion.
- Q: b)Describe an important industrial application of one of the above devices (apart from transformers)C)Explain how this device works-that is ,what the electricity actually does
- A transformer is a device that allows you to easily and efficiently convert an AC voltage to a different voltage. When you do this, the current is converted in the opposite ratio. For example, if you have a 100 volt 1 amp source and you convert it to a 1000 volt source, it will have capability of 0.1 amp. It is made by winding wires on iron cores. See the reference for details. It is very important for the transmission of AC power, as it can be changed to a very high voltage for efficient distance transmission, and back to low voltage for use in homes. .

- Q: HiCan anybody help with the below question?A 400V, 3 phase supply is connected through a 3 phase loss-free transformer of ratio 1:1, which has its primary connected in mesh and secondary in star, to a load comprising three 20 ohm resistors connected in deltaCalculate the currents in the transformer windings, in the resistors and in the lines to the supply and the load. Find also the total power supplied and the power dissipated by each resistor.Thanks in advance
- The transformer is connected delta-wye (mesh-star), so the secondary voltage is: Vs400V x sqrt(3) 692.82V (line-to-line) Current in each resistor is: IrE/R692.82V/20ohm34.64A Line current on secondary is: Ils34.64A x sqrt(3) 60.00A Current in each secondary winding: Isw Ils 60.00A Current in each primary winding: Ipw Isw 60.00A (because windings are 1:1) Primary line current: Ilp Ipw x sqrt(3) 60.00A x sqrt(3) 103.92A Check: Primary and secondary kVA should be the same: kVAp400Vx103.92Axsqrt(3)/100072.0kVA kVAs692.82Vx60.00Axsqrt(3)/100072.0k It checks Since load is purely resistive, kVAkW.

- Q: I am looking into purchasing a counter top coffee roaster that requires a 30 Amp 120 outlet; manufacturer says it uses about 21A.The only plug/circuit that can handle this load at this time is a 240 V outlet. We have a gas stove and we are not currently using the circuit.Does anyone know of a manufacturer that makes a external/freestanding step down (240 to 120) voltage transformer / regulator that I can plug into a grounded (North American) 220V outlet ? Note: a) I don't need it to be variable, just a fixed 240V to 120V is perfect. b)It would also need some sort of internal voltage regulation/ stabilization as erratic voltages would affect the (coffee) roast.

- Q: The total power of 590kw, this transformer can bear it? It is best to give a formula, do not copy the.
- 630KVA transformer generally according to the efficiency of 0.8, about 504KW load, the capacitance compensation will increase the power factor to 0.95, the load power also increased with about 590KW near the existing total power 590kw should be installed capacity, the actual load should Less than 90% can load. 630KVA Transformer rated current: I = P / 1.732 / U = 630 / 1.732 / 0.38 ≈ 957 (A) The total installed power of 590kw, load rate or full load rate of about 0.9, the capacitance compensation to the power factor increased to 0.95 when the average power factor of about 0.9, the load current: I = P × 0.9 / 1.732 / U / COSφ = 590 × 0.9 / 1.732 / 0.38 / 0.9 ≈ 896 (A) 300kw load current (when COSφ is 0.8): I = P / 1.732 / U / COSφ = 300 / 1.732 / 0.38 / 0.8 ≈ 570 (A) Large cross-section copper wire per square safe current carrying about 2.5 ~ 3A, need to wire cross-section: S = 570/3 = 190 (square)
- Q: I check the voltage between x1 and x2 I got 120v but between x1 and ground on primary I got 40v and between x2 and ground on Primary I have 50v, if I connect x2 to ground won't it short the transformer? Thank you
- NO IT WILL NOT SHORT THE XFORMERCONNECT X2 TO GROUND. PREFERABLE AN EARTH GROUND, BUT AT LEAST THE ELECTRICAL GROUND.
