VII. Paralleling operation (wiring refer to the appendix): MX generators are suitable for paralleling as full damping winding. But, before paralleling, each unit of generator should be started up, operated and adjusted. A. Base conditions of paralleling operations: 1 . Additional paralleling circuitry a. Voltage regulator-paralleling provisions b. Paralleling current transformer(s) c. Paralleling provisions on governor controls d. Switch gear 2. The voltage and frequency must be the same for all sets with voltages in phase. 3. The generators must have the same phase sequence rotation. 4. The voltage regulation characteristics of the individual generators should be similar. 5. The driving engines should have the same speed regulation characteristics and the governors should be adjusted to give the same speed regulation. B: Reactive load control and adjustment: When two identical generators are operating together in parallel and an unbalance occurs in fiel...

What do you know about Marathon MX Series three phase AC synchronous brushless generator? In the previous article, we have talked about the general information and installation of the generator. In this post, you will learn the inspection, operation and maintenance of Marathon MX Series 3 phase alternator. V. Inspection and operation 1. Inspection: a. Though the generator, AVR and auxiliary devices are solid and well insulated, if the generator was stored for longtime, it might be moistened or failed and should be inspected carefully before operation. b. Measure the insulating resistance of windings against the ground by megohm-meter, if the value is less than 2 MΩ in cold condition, the generator should be dried. Caution: At measuring, the electronicelements and capacitor should be short circuit, and the AVR should be disconnected to avoid damage. c. Make sure all connecting joints are tight and connected well. d. Be sure the frame is properly grounded, and ground...

Synthetic lubricating oil Synthetic oils for use in diesel engines are primarily blended from synthesized hydrocarbons and esters. These base oils are manufactured by chemically reacting lower molecular weight materials to produce a lubricant that has planned predictable properties. Synthetic oil was developed for use in extreme environment where the ambient temperature may be as low as -50°F[-45°C] and extremely high engine temperatures at up to 400°F[205°C]. Under these extreme conditions petroleum base stock lubricants (mineral oil) do not perform satisfactorily. Synthetic lubricating oil for use in areas where the ambient temperature is consistently lower than -13°F[-25°C]. Synthetic lubricating oil may be used at higher ambient temperatures provided they meet the appropriate API Service categories and viscosity grades. Arctic operation For engine operation in areas where the ambient temperature is consistently below -13°F[-25°C] and where there is no provision to k...
