    The application of multifunction digital relays to protect medium voltage power transformers has become a common industrial practice. Industrial transformers, unlike utility transformers, frequently use neutral grounding resistors to limit ground current during faults to the 200-400 A level on medium voltage systems. This paper discusses why these types of transformers require sensitive ground dif... View full abstract»

    TN-island grounding system is an effective way to both protect persons from shock hazard in installations with contained demand load, and greatly limit electrical interferences among systems. This distribution system, which utilizes separation transformers, grounded on the secondary sides, allows one to supply loads broken into "islands" as independent electrical areas. TN-island fits best the sup... View full abstract»

    Multiple grounded neutral systems require that, on most land-based AC current service installations, the bonding conductor used to connect the non-current-carrying metal parts of equipment, the system grounded conductor (neutral), and the grounding electrodes be bonded together at the service entrance box. Users, thus, share their ground with the serving utility's neutral ground. This interconnect... View full abstract»

    The reliability of the electrical power system supply requests often set up more sources. For a good design, a proper installation and operation, all the admissible sources sets and the related operating procedures have to be defined, including contingency conditions. The studies of the integrity procedures have to consider load flow and short circuits analysis . The clear evaluation of all the so... View full abstract»

    An innovative method is proposed where charging current can be measured and grounding resistors sized without staging a fault. Overvoltages have caused damage to equipment and voltage transformer fuse blowing an ungrounded 4.8 kV delta distribution system. Three causes are suspected: single-line-to-ground faults, multiple restrikes and ferroresonance. The first is the most likely. The existence of... View full abstract»

    Measurements of pulsating voltage taken by an expert using a digital multimeter did not represent the magnitude of voltage or the total energy. Some experts have used the same type meter without completely explaining or showing what portion of the energy had not been recorded. A heuristic approach of showing what the voltage signature probably looked like using a signal generator and a digital sto... View full abstract»

    The purpose of this paper is to point out deficiencies in both the arguments presented and the opinions expressed by Mr. Donald W. Zipse in the paper entitled "equipotential planes, a figment of the imagination". In this paper the author opines that equipotential planes are dangerous, but presents no theoretical basis or creditable evidence to support this opinion. The author implies that voltage ...

    This paper presents an efficient, small-sized, and cost-effective single-switch power-factor-correction (PFC) scheme for high-frequency electronic ballasts. The circuit topology originates from the integration of a buck-boost power-factor-correction converter and a class-E electronic ballast. Only one active power switch is commonly used by both power stages to save the cost of active switches and... View full abstract»
