Ans. The equation is kW= kVA *pf. In general kW is active or useful power and kVA is the vector sum of active power and reactive power. The equation is kW= kVA *pf.

Some of my poems have rather explicit contents and/or language, so I chose to give them an R rating to indicate this to a possible reader - so that you'll be more or less prepared for what awaits you. If you're an innocent minor, ask a parent; if you're a worried parent, explain it to your kid. I'm in no way affiliated with any rating agency, this rating has been given completely voluntarily.

Yes. The regulations define a rating of record as the performance rating completed at the end of the appraisal period that reflects performance over the entire period, or an off-cycle rating of record given when a within-grade increase (WGI) decision is not consistent with the employee's most recent rating of record and a more current rating of record must be prepared. These are the only times that a rating of record can be issued. See similar questions...

A Kilowatt is a measure of power equaling 1,000 watts, describing the rate of energy use. For example, ten 100-watt light bulbs use one kilowatt of electricity. See similar questions...

W” indicates actual power consumption, while “VA” is potential power. The electricity used by electrical appliances when they are actually working is called power consumption (W). See similar questions...

The HAPLR Index is similar to an ACT or SAT score with a theoretical minimum of 1 and a maximum of 1,000. Most libraries scored between 260 and 730, so scores above and below those numbers are remarkable. Consider the chart below for the libraries in the over 500,000-population category, for a short idea of the rating methodology. A library above the 75th percentile for expenditure per capita of $38.50 will get a higher score on this measure than one below the 25th percentile. See similar questions...

YES, even though one primary (or secondary) winding may be all you need from the look of the schematic and/or specs, the unit was designed to run ALL windings. Example - you have a dual primary unit for 115/230VAC operation. You have 115VAC power, you must hook BOTH primaries in parallel (make sure you connect them in phase). If you try to use only one primary (or secondary), the unit will probably overheat and voltage regulation will be poor. See similar questions...

In regard to transformers in vaults associated with large commercial buildings, or on the other side of a wall in a commercial building, yes they are a problem. Extremely high fields can be created in occupied areas adjacent to these units. The same applies to other components of the electrical system connected to the transformers. Possibly. Requesting that the utility move or modify their lines is usually not within the realm of reality, and shielding is impractical for a number of reasons. See similar questions...

Since 1994 there has been an annual Transformers convention, usually called "BotCon" (for two years it was "The Official Transformers Collectors' Convention" (OTFCC)). The convention is such a major event in the fandom that there is a full section of the FAQ (I/D) devoted to it, as well as the smaller, unofficial conventions that have become more widespread in the last few years.

Transformers connected in reverse, to proper input voltages, will provide correct nameplate voltage output, albeit reversed. However, for transformers rated 2 KVA and below, the output voltage would be less than the nameplate rating, since smaller KVA transformers have a greater turns ratio compensation on their low voltage windings. CAUTION: When reverse connecting a delta-wye transformer, a wye primary will be created. Wye primaries may cause problems and are not recommended. See similar questions...

The KeyCompete rating is a score given to a domain and keyword pair(Ad). This score is calculated using the coverage and the rank of the Ad. Coverage is determined by how many search engines the Ad was found in. Rank is determined by the position of the Ad in the search engine. The more coverage and higher ranking, the better the rating.

Assume your power company charges you $0.10 per kW-Hour. This means that it would cost you 10 Cents to run a 1000 Watt projector for one hour while watching a movie in your living room. Now assume that you wanted to run that same movie projector by bike pedal power generator. You would need 10 adults in good shape. Each one would average about 100 Watts. So 10 People all at once pedaling for an hour would earn a total of $0. See similar questions...
