HOLDING TO ELECTRICAL SPECIFICATIONS

2009-02-07T00:08:00.004+08:00

Engineers should maintain their positions on electrical system design, whether for code issues, good design practice- or the owner’s best interest "Why on earth did you design it that way?" This is a plaint often heard from the contractor, construction manager, or owner when documents are issued for construction. More often than not, the statement is liberally littered with modifying expletives.

PRICE AND COST ANALYSIS

2009-02-06T23:20:00.002+08:00

Some form of price or cost analysis should be performed in connection with every procurement action, regardless of whether the organization is a vendor or a subrecipient. The form and degree of analysis, however, are dependent on the particular subcontract or purchase, and the pricing situation. Determination of pricereasonableness through price or cost analysis is required even though the

PROJECT MANAGEMENT

2008-08-18T20:58:00.004+08:00

A successful project starts with solid planning and ends with a smooth hand-off…The phrases “on time” and “within budget” are often used in discussions of project delivery, but how often can they actually be used to describe a project? Project schedules can fall apart for any number of reasons, but it's often a case of poor planning and a lack of communication. And if participants have uncommon

1. Sleep less. This is one of the best investments you can make to make your life more productive and rewarding. Most people do not need more than 6 hours to maintain an excellent state of health. Try getting up one hour earlier for 21 days and it will develop into a powerful habit. Remember, it is the quality not the quantity of sleep that is important. And just imagine having an extra 30 hours

Static Power Factor Correction / Improvement

2007-11-14T19:57:00.000+08:00

As a large proportion of the inductive or lagging current on the supply is due to the magnetising current of induction motors, it is easy to correct each individual motor by connecting the correction capacitors to the motor starters. With static correction, it is important that the capacitive current is less than the inductive magnetising current of the induction motor. In many installations

Star (Wye) / Delta Starter

2007-11-14T19:48:00.000+08:00

The Star/Delta starter is probably the most commonly used reduced voltage starter, but in a large number of applications, the performance achieved is less than ideal, and in some cases, the damage and interference is much worse than that caused by a Direct On Line starter.The Star/Delta starter requires a six terminal motor that is delta connected at the supply voltage. The Star Delta starter
