Generator Maintenance Testing

Handbook of Large Turbo-Generator Operation and Maintenance, None

Generator maintenance testing refers to tests that are done generally off‐line or for some special condition, as opposed to online testing, which is actually a form of monitoring for diagnostic purposes while the generator is producing power. If there is stator cooling water left in the winding, it will alter the test results and give a distorted picture of the ...

Development of a successful direct-current 2000-kw. unipolar generator

Proceedings of the American Institute of Electrical Engineers, 1912

This paper is not intended to be a theoretical discussion of the principles of unipolar machines; neither is it a purely descriptive article. It is rather a record of engineering experiences obtained, and difficulties overcome, in the practical development of a large machine of the unipolar type. For those who are interested in the designs and development of electrical machinery ...

  • Generator Maintenance Testing

    Generator maintenance testing refers to tests that are done generally off‐line or for some special condition, as opposed to online testing, which is actually a form of monitoring for diagnostic purposes while the generator is producing power. If there is stator cooling water left in the winding, it will alter the test results and give a distorted picture of the insulation condition. The main tests done on the hydrogen seals are liquid penetrant (LPI) for cracks and other surface damage, and ultrasonic testing (UT) for babbitt bonding to the seal‐ring components. Rotor winding shorted turns, or interturn shorts, can occur from an electrical breakdown of the interturn insulation, mechanical damage to the interturn insulation allowing adjacent turn‐to‐turn contact, or contamination in the slot, which allows leakage currents between turns.

  • Generator Design and Construction

    This chapter focuses on the construction of the generator and its major individual components. The stator winding information regarding winding phases, parallels, and connections can be explained using both developed view and circular view‐type winding diagrams. It is the main body of the rotor forging that carries the flux, in both the body of the forging in the pole and under the winding area of the rotor. In addition to the electromagnetics of the main flux distribution across the airgap and in the main body of the stator and rotor, there are end‐region effects from the flux produced. With directly cooled stator winding machines, the armature reaction and stray flux are high and require flux shielding at the stator core ends to minimize the losses in the core ends and the subsequent higher temperatures.

  • Development of a successful direct-current 2000-kw. unipolar generator

    This paper is not intended to be a theoretical discussion of the principles of unipolar machines; neither is it a purely descriptive article. It is rather a record of engineering experiences obtained, and difficulties overcome, in the practical development of a large machine of the unipolar type. For those who are interested in the designs and development of electrical machinery there may be many points of very considerable interest in this record. Some of the conditions of operation, with their attendant difficulties, proved to be so unusual that it is believed that a straightforward story of these troubles, and the methods for correcting them, will be of some value as a published record.

  • Stator Inspection

    This chapter aims to serve as a guide to learning the specific problems and failure mechanisms and their identification that will make it possible to correctly assess intrinsic risks for a given design, and explicit signs of deterioration and damage and/or impending failure. The main external components of the stator frame and casing that require inspection and periodic maintenance are the frame footing and bolts, the generator foundation, the seismic supports, the grounding cables, the piping and connections, the generator end brackets, the end‐shield bearing supports, the bearing insulation and pedestals, and the space heaters. It is more serious when cracks occur in the phase connectors or support ties. The main internal components of the stator frame and casing that require inspection and periodic maintenance are the support structure, wiring, and hardware. Most large machines include air/gas baffles to direct the cooling air or hydrogen to and from the fans.

  • Distributed Windings in ac Machinery

    Many AC machines are designed based on the concept of a distributed winding. Several concepts are needed to study this type of AC machinery. These concepts include distributed windings, winding functions, rotating magnetomotive force (MMF) waves, and inductances and resistances of distributed windings. In this chapter, these principles are presented and used to develop the voltage and flux‐linkage equations of synchronous and induction machines. The chapter sets forth methods to describe distributed windings (discrete and continuous), and analyzes distributed winding devices. Air‐gap MMF and the relationship of this MMF to the stator current are also considered. The chapter then focuses on calculation of the electrical parameters (specifically inductance and resistance) of rotating electrical machines. Voltage equations and winding inductances for an elementary three‐phase synchronous machine and a three‐phase induction machine are finally derived.

  • IEEE Draft Recommended Practice for Quality Control Testing of External Discharges on Stator Coils, Bars and Windings

    This guide describes the procedure for quality control testing of external discharges on stator coils, bars and windings of large air-cooled ac electric machines.

  • Discussion on “the squirrel cage induction generator” (Hobart and Knowlton), “single-phase induction motors” (Branson) and “motor starting currents as affecting large transmission systems” (Lincoln). Boston, Mass., June 28, 1912. (see proceedings for June and July, 1912)

    Lee Hagood: My remarks will be confined to the question of exciting current in connection with Mr. Hobart's and Mr. Knowlton's paper. As you will see from reading their paper, the matter of exciting currents bears very much on the question of air gaps. To some extent, the amount of exciting currents required may appear to be a very great objection to these machines. I wish to make the point that neither the design of the machine nor its application should be very much restricted on account of exciting current.

  • Distributed Windings and Rotating Electric Machinery

    This chapter focuses on a complicated winding arrangement known as a distributed winding, which is often used in rotating electric machinery. In these machines, the goal is to establish a continuously rotating set of north and south poles on the stator, which interact with an equal number of north and south poles on the rotor, to produce uniform torque. The winding function has three important uses. First, it is useful in determining the MMF caused by distributed windings. Second, it is used to determine how much flux links a winding. Third, the winding function is instrumental in calculating winding inductances. The chapter talks about the air-gap magnetomotive force (MMF). It explains the calculation of inductances of distributed windings. The problem of the computation of leakage inductance of a stator winding and the problem of finding the resistance of a distributed winding are considered.

  • Enhancement of a Thrust Force of a Tubular Electromagnetic Launcher With Transverse Flux Configuration by Leakage Flux Suppression

    This paper presents an approach for enhancing the thrust force of a tubular transverse flux permanent magnet linear machine (TFPMLM) that has been developed for electromagnetic applications. It is shown that, by introducing auxiliary cores to suppress the leakage flux, the thrust force of the tubular TFPMLM can be significantly enhanced, by ~ 130%, under the same volumetric constraints. The effectiveness of the proposed technique is validated by extensive three-dimensional finite element computations.

  • Loss Analysis of Induction Motors by Considering Shrink Fitting of Stator Housings

    The losses of induction motors are analyzed using the combination of stress and electromagnetic field analyses that consider the effect of shrink fitting of stator housings. In the combined analyses, the variation in the stress effect with the angle between stress and flux vectors are taken into account using an equivalent stress. The calculated losses are compared with measured results in order to confirm the validity. It is revealed that not only the core loss, but also the primary copper loss and eddy current loss of the stator housing, increase by the shrink-fitting stress according to an increase in the reluctivity of the stator core.
