共箱封母单相接地保护配置探讨

大型发电机组厂用高压变压器中性点一般采用经电阻接地的方式，其低压侧共箱封母发生单相接地时，零序电流较大，但此时高变差动保护可能不会动作；且配置的“零序过流保护”也只动作出口跳厂用电源开关，不能完全切除故障，形成零序保护动作死区。衣文就厂用高压变压器低压侧共箱封母单相接地时零序保护配置进行探讨，达到消除该死区的目的。

浅谈110kV变电站接地变压器保护误动与解决措施

目前110kV变电站10kV馈线越来越多地采用电缆出线,以致10kV系统单相对地电容电流大幅度增加。为抑制单相接地时产生的过电压幅值,110kV变电站10kV电网系统开始加装接地变压器,构成低阻接地接线方式,形成一条零序电流的通道,以便当10kV系统发生接地时,根据接地点所在位置,由相应零序保护有选择性动作将接地故障隔离,以防电弧重燃引发过电压,保证电网设备安全供电。     

关于撤除零序量的变压器差动保护的校验方法

变压器在正常运行或外部故障时可能在高低侧存在零序电流差,所以变压器保护装置为了防止差动保护误动作,有必要在计算差动电流时把所有绕组电流中的零序分量撤除掉,利用撤除了零序电流量的高低压侧电流计算差动和制动电流值.在这种情况下加单相电流进行校验和加三相电流校验时的差动电流及制动电流之间存在差异,本文给出了在在加单相电流进行校验的差流计算公式并进行了现场校验.

Spirituality In (and Out) of the Classroom: A Pragmatic Approach

This paper is divided into two sections. In the first section, I discuss “what is spirituality?” and in the section that follows, I examine some of the implications of my definition to the teaching of spirituality in an undergraduate business ethics course. For the purposes of this paper, spirituality is defined as the planned experience (the inner feeling) of blending integrity and integration through 1 – acceptance (of the past), 2 – commitment (to the future), 3 – reasonable choice, 4 – mindful action, and 5 –continuous dialog (both internal and external). This definition is a work-in-progress and offered mainly as a point of departure rather than a final destination.     

A Question of Trust: the Pursuit of Consumer Trust in the Financial Sector by Means of EU Legislation

The decrease in consumer trust in the financial sector and the attempts to restore it are receiving a great deal of interest, especially since the financial crisis at the end of 2008. EU legislation is one of the ways that attempts have been made to regain the trust of investors. In the second section, the concept of “trust” will be subjected to an in-depth yet not exhaustive examination, with the aim of reducing its elusiveness. The third section will discuss three recent EU proposals. Examination of these legislative proposals reveals that (1) the term “trust” is not precisely defined, and (2) without stating further reasons, the restoration of trust in the financial sector is considered a worthy goal. In light of the aforementioned, the fourth section will address the desirability of clarity regarding the term “trust.” The fifth section will then assess whether legislation is a suitable means to restore consumer trust, and the sixth section explores whether the restoration of consumer trust in the financial sector is a worthy goal. Indeed, the European legislator and other policymakers seem to consider a low level of consumer trust a bad thing, a high level of consumer trust a good thing, and a higher level of consumer trust an even better thing. This article will argue that it is doubtful whether EU legislation is a suitable means for restoring consumer trust in the financial sector and, moreover, that considering the perverse incentives in the current financial sector, among other things, a realistic degree of trust, implying a certain distrust, appears preferable.

Making the ‘handmade’ bike and trying to make a living: market objects,field-configuring events and some limits to market making

In line with growing interest in craft and maker economies, I examine the resurgence of handmade bicycle fabricators (“framebuilders”) in the U.S. since the early 2000s. I provide an account of one of the driving elements of this framebuilding renaissance, the North American Handmade Bicycle Show, considered as a “field-configuring event” through – and around – which forms of market-making and market object stabilization processes were achieved. I focus in particular on the way in which the “handmade bike” as a market object was stabilized and defined. Expanding on the “markets as practice” literature, I take up a larger concern with how these market-making and field-configuring dynamics connect to the material position of those within the field and their pursuit of livelihood. I find that, paradoxically, the particular successful stabilization of the “handmade” bicycle achieved around the show was difficult to sustain as a business model for many framebuilders.

Advancing transcendent development: An in-depth review of developmental corporate social responsibility’s value proposition,inhibitions, and inclusive sustainable development prospects

This article offers a methodologically innovative Representative Literature Review of 260 Development-Oriented Corporate Social Responsibility publications explicating why the nascent domain’s early momentum has seemingly stagnated. Using mixed-methodological citation network analysis informed by Applied Thematic Analysis research design principles, this in-depth literature review unearths a causal set of Impediments, leading to Inhibitors restraining Developmental Corporate Social Responsibility’s inclusive sustainable developmental potential. The Seven Impediments and their Seven Inhibitors are ultimately meta-thematically synthesized into the following Three Inhibitions presently stifling the field: “(I) Ignorance,” “(II) Isomorphism,” and “(III) Inharmony.” Resultantly, this article offers three contributions for addressing these Inhibitions. First, academic scholarship is offered knowledge of how “(I) Ignorance” may be curbed by producing research that retains and builds upon knowledge cumulatively, instead of losing it to fragmentary dissipation born of scholarly incoherence. Second, institutional policymakers are offered pathways for transcending superficial “(II) Isomorphism” by enforcing regulation that engenders ethical business conduct by filling critical institutional voids in developing context jurisdictions. Finally, this review outlines how the Inhibition of “(III) Inharmony” may be pragmatically transcended by harmonizing unconscious ontological dissonance through self-awareness and reflexive virtue development by synergistically enacting individual Moral Courage, Moral Tact, and Moral Imagination tempered by African Vhuthu/Ubuntu.     

Paradisal discourse: A critical analysis of marketing and consuming Hawaii

The marketing of certain tourist destinations can be analyzed as discourse that conveys meaning to the consumer and to the consumed. This discourse, which I refer to hereafter as paradisal discourse, is a combination of Orientalism, travel writing, discourse of the Primitive, and diverse forms of Otherness. This paper begins with an exploration of discourse as a tool of knowledge and of power, illustrated through a detailed assessment of Said's Orientalism and other relevant works and concepts. The discourses of “Orientalism,” “primitivism” and travel writing are likened to the paradisal discourse found in the marketing of certain types of tourist destinations. The second section of the paper presents an historical and cultural analysis of the concept of paradise in Western society, summarizing the elements which, over time, have come to form this distinctive discourse. The third section of the paper assesses the way in which this discourse forms the framework by which a specific tropical paradise, Hawaii, is marketed and consumed today.     

To stay or to leave: The moral dilemma of divestment of South African assets

The question of U.S. divestment of South African assets can be segmented into two major issues: (1) corporate behavior in a general sense and (2) nature of the product produced. The first issue has four sub-issues: (1) Is apartheid immoral? (2) Do corporations have any social responsibility? (3) Do the rights of South African blacks concerning the issue of apartheid outweigh those of the corporations to do business freely? (4) Are the benefits to blacks greater with divestment than without? The term “benefits” is then defined in both macro and micro dimensions. A “NO” answer to any one of the several questions would lead to the conclusion that there is no moral obligation for U.S. firms presently in South Africa to divest. The analysis presented will conclude that the answer to the first three questions is “yes”. Further, the answer to the first half of the fourth question (macro benefits) will be determined to be “no”. The micro benefit issue, namely, the nature of the product produced, will then be evaluated using a model based on which group benefits most from the item produced. Assuming corporations are successfully meeting their moral obligations under questions # 2 and # 3, then the general conclusion will be reached that firms producing items of direct benefit to the black community should stay; firms producing items of direct benefit to the government should divest; and no generalized model for analysis can be assumed for firms producing items which benefit both groups equally. Finally, a brief discussion is presented of the issue of obligation for positive action against apartheid, both political and economic, on the part of U.S. corporations.     

The Japanese employment system in transition

In the post-bubble era, Japan is going through major structural upheavals and the relevance of the five perspectives presented here on the implications of these changes for the Japanese employment system can hardly be overstated. The institutions and practices of the Japanese employment system are closely linked to the Japanese model of skill formation, human resource management and innovation. The relevance of “lifetime employment” for the accumulation and preservation of knowledge within companies has been documented for example in comparative studies on the Japanese and US semiconductor industries. The knowledge sharing, problem solving capacities and high commitment of Japanese employees are very much enhanced by the late selection characteristics as implied by “seniority” based promotion schemes. If the skills, the innovative capacities and the commitment of Japanese employees have been so much supported by the salient features of the Japanese employment system, it is essential to see what is happening to the latter when reflecting on the future of the former. This is the prime purpose of this article. Each of the following sections looks at specific changes in the economic environment, that are challenging the further viability of “traditional” human resource management practices: In particular, the first section looks at the rapid aging of the work force as a key “domestic” factor, while the second section looks at the implications of Japanese internationalisation in the post-bubble era and, especially, the “hollowing out” of the industrial system due to increasing competitive pressures from low labor cost countries. Adaptations necessitated by these challenges have already transformed the Japanese employment system and will continue to do so, as is discussed in the third section. It is not difficult to guess that this will have repercussions on the process of knowledge creation and transfer in the Japanese economy and the final section therefore looks specifically at the changes to the Human Resource Management system in the Japanese Innovation System.
