It is safe to estimate that the cost of fixing a problem increases by roughly an order of magnitude in each phase of development.requirements phase (cost 1)preliminary design phase (cost 10)detailed design phase (cost 100)coding phase (cost 1000)testing phase (cost 10000)So as an estimate if a problem is not found until test phase it will cost roughly 10000 times as much to fix as it would if the problem had been found in the requirements phase.
In order to answer your question, firstly, we have to accurately establish your supply.Is it 2 phase or 2 wire?2 phase is two active conductors, i.e. 2 live wires with reference to neutral or ground2 wire is single phase, an active and a neutral conductor.2 phase supply is uncommon.Single phase (2 wire) is the more common supply and for installations with large loads three phase, or, more appropriately 3 phase and neutral (4 wire) is used.Please confirm your supply so that a detailed answer can be provided.
There is phase to phase voltage in 3 phase system.AnswerYou don't get voltage 'phase-to-phase'; it's 'line-to-line'!
single phase, double phase & three phase
Often the advantages of three-phase power for motors and other 3 phase equipment make it worthwhile to convert single-phase to three phase power. Rural business or farm properties, and urban residential area power consumers, may not have access to a 3 phase supply, or may not want to pay for the extra cost of a 3 phase service, but may still wish to use three-phase equipment. Some of such 3 phase converters may also allow the frequency (see also frequency converters) to be varied allowing for different equipment frequency requirements (50Hz, 60Hz, 400Hz, etc.) and also for motor speed control (VFDs). Some locomotives are driven by 3-phase motors with 3 phase converters converted from the incoming supply of either DC or 1 phase AC. The two main types of 1 phase to 3 phase converters are Rotary Phase Converters and Static Phase Converters. Read below for more about 3 phase converters.There is a big difference between phase converter types available on the market today. Most 3 phase converterssold by companies today do not produce actual balanced 3 phase power. This is why is very important to select a 3 phase generating phase converter which will run on single phase power and generate true balanced smooth 3 phase power. Below is a comparison of several technologies available today.3 Phase Converter Types and Comparison Good old fashioned research will help guide you to make sure that you are able to get the proper product to give you balanced 3 phase power. The US Phase Converter Standards Organization has some excellent guides to help choose the appropriate technology for your need comparing them side by side. Check out their Phase Converter Type Comparison Chart to read about the strengths and weaknesses of each type side by side with their ratings on quality, durability, safety, and 3 phase power quality produced.
During the DESIGN PHASE of the SDLC or "System Development Life Cycle" is where a detailed plan for programmers to follow is developed.
The key differences between the G1 phase and G2 phase of the cell cycle are that the G1 phase is focused on cell growth and preparation for DNA replication, while the G2 phase is focused on further growth and preparation for cell division. In G1 phase, the cell is actively growing and carrying out its normal functions, while in G2 phase, the cell is preparing for mitosis by synthesizing proteins and organelles needed for cell division.

A sideways movement is the movement of prices between a strong support and resistance. This is called a consolidation phase. During this phase the supply and demand are tight. The market tends to consolidate during this phase before it starts to make a movement higher or lower.
The stages of natural disaster recovery typically include the emergency response phase, the relief phase focused on meeting basic needs, the rehabilitation phase aimed at restoring infrastructure and services, and the reconstruction phase focused on long-term recovery and building resilience against future disasters. Throughout these stages, there is a focus on collaboration among various stakeholders, including government agencies, non-profit organizations, and communities.
market analysis phase information is gathered by surveying the customer or clients such as feasible study of new products.Specification phase can be collected either from the customer or within the organisation in the form of requirement, technical, pass design or pattern standard.Design/Development Phase Ideas or market requirement are given specific physical form- initial sketching or conceptual design through prototype development to detailed drawings and specifications needed actually to make the product. CNC machining could be used in producing the model of the prototypePreparation phase generally groundwork preparation of tools in making the productManufacturing phase start up of the manufacturing of the product. manufacturing can be done using cnc machine tools if needed.Involves marketing, sale and delivery of products.Bring to customer phase
