Insulation Measurement and Supervision in Live AC and DC Unearthed Systems by Piotr Olszowiec Pdf

Low voltage unearthed (IT) AC and DC systems are commonly applied for supply of power and control circuits in industry, transportation, medical objects etc. The main reasons for their use are high reliability and numerous advantages offered by isolating them against ground. Insulation level is a decisive factor for networks operational reliability and safety. Insufficient insulation-to-ground resistance can cause various disturbances. Though ground faults in IT systems do not make networks operation impossible, they may cause severe problems with their safe functioning. In this book the most important issues concerning normal operation and ground fault phenomena are described in concise form. Numerous methods of insulation resistance and capacitance measurement in live circuits are presented. Important other procedures of these parameters determination based on measurement and calculation are explained and reviews of selected insulation resistance measurement devices as well as earth fault locating systems are included. For the text understanding merely basic knowledge of electrical circuits theory is required. This book is addressed to electrical engineers, technicians and students of this specialty and may also serve as an academic handbook.

The President and Immigration Law by Adam B. Cox,Cristina M. Rodríguez Pdf

Who controls American immigration policy? The biggest immigration controversies of the last decade have all involved policies produced by the President policies such as President Obama's decision to protect Dreamers from deportation and President Trump's proclamation banning immigrants from several majority-Muslim nations. While critics of these policies have been separated by a vast ideological chasm, their broadsides have embodied the same widely shared belief: that Congress, not the President, ought to dictate who may come to the United States and who will be forced to leave. This belief is a myth. In The President and Immigration Law, Adam B. Cox and Cristina M. Rodríguez chronicle the untold story of how, over the course of two centuries, the President became our immigration policymaker-in-chief. Diving deep into the history of American immigration policy from founding-era disputes over deporting sympathizers with France to contemporary debates about asylum-seekers at the Southern border they show how migration crises, real or imagined, have empowered presidents. Far more importantly, they also uncover how the Executive's ordinary power to decide when to enforce the law, and against whom, has become an extraordinarily powerful vehicle for making immigration policy. This pathbreaking account helps us understand how the United States ?has come to run an enormous shadow immigration system-one in which nearly half of all noncitizens in the country are living in violation of the law. It also provides a blueprint for reform, one that accepts rather than laments the role the President plays in shaping the national community, while also outlining strategies to curb the abuse of law enforcement authority in immigration and beyond.
