lol…No it is all NACHI that takes care of my services…and they are awesome about it…It is just hard to get chapters to do more than 2-3 hours…and to bring me in they need to have a chapter meeting that is going to last a whole saturday…and make it 8 hours to make it worth me coming out is all.
I am paid by NACHI be it a Chapter Meeting or NCT Event…
Joe F…I wish more chapters were interested in electrical knowledge…as I am sure I would come to see them and do a 8 hour stint…and even a 2 day 16 hour stint if they REALLY want to get advanced…or even a 8 hour Grounding and Bonding Class…what ever it takes.
FYI…For Joe…You might find this interesting as out conversation was cut short my friend.
two phase Two-phase electrical power was an early 20th century polyphasealternating current electric power distribution system. Two circuits, or “phases”, were used, with voltages 90 electrical degrees apart in time. Usually circuits used four wires, two for each phase. Less frequently, three wires were used, with a common wire with a larger-diameter conductor. The generators at Niagara Falls installed in 1895 were the largest generators in the world at the time and were two-phase machines. Some early two-phase generators had two complete rotor and field assemblies, mechanically shifted by 90 mechanical degrees to provide two-phase power.
The advantage of two-phase electrical power was that it allowed for simple, self-starting electric motors. In the early days of electrical engineering, it was easier to analyze and design two-phase systems where the phases were completely separated, since this avoided the need for the effect of unbalanced loads. It was not until the invention of symmetrical components that three-phase power systems had a convenient mathematical tool for describing unbalanced load cases. The revolving magnetic field produced with a two-phase system allowed electric motors to provide torque from zero motor speed, which was not possible with a single-phase induction motor (without extra starting means). Induction motors designed for two-phase operation use the same winding configuration as *capacitor start single-phase motors. Three-phase electric power requires less conductor mass for the same voltage and overall amount of power. It has all but replaced two-phase power for commercial distribution of electrical energy, but two-phase circuits are still found in certain control systems.
Two-phase power can be derived from a three-phase source using two transformers in a Scott connection. One transformer primary is connected across two phases of the supply. The second transformer is connected to a center-tap of the first transformer, and is wound for 86.6% of the phase-to-phase voltage on the 3-phase system. The secondaries of the transformers will have two phases 90 degrees apart in time, and a balanced two-phase load will be evenly balanced over the three supply phases.
Three-wire, 120/240 volt single phase power used in the USA and Canada is sometimes incorrectly called “two-phase”. The proper term is split phase or 3-wire single-phase.
James - I appreciate your skepticism with regard to NACHI Certified Training; however, with respect to our relationship with the NACHI Chapters, our experience has been just the opposite of what you are inferring. NCT’s relationships with the Chapters have been all about increased growth and enthusiasm, both for NACHI and for the local NACHI Chapter membership.
Typically, we at NCT are signing up a minimum of 5 new memberships for NACHI at each event. NCT is acting as a magnet to many inspectors of other inspection associations and attracting them to NACHI. This is helping local chapter growth and is providing new blood for the chapter which always stimulates growth.
Also, regarding our relationships with the various NACHI Chapters, NCT has been known to bring excellent, in-depth training (up to 8 hours) which is not normally done at a Chapter meeting. NCT promises to work with any NACHI Chapter in any way that would best suit the education needs of their Chapter.
If you have some additional pointers for me that would induce both NACHI Chapter growth and continued growth in NACHI membership, please call or email me - I am very open to any honest criticism (and enthusiasm) anyone might have. We are striving to be the very best in one-day home inspection education.
Bottom line, NACHI Certified Training is all about “Inspection Excellence Through Education” - the more you know, THE LESS STRESS you will achieve at every one of your inspections. I speak from experience on this one and I have a driving passion to get other inspectors energized about their business!
