  • causing a voltage sag with duration of more than 1 cycle occurs within the area of vulnerability. However, faults outside this area will not cause the voltage to drop below 0.5 pu. The same discussion applies to the area of vulnerability for ASD loads. The less sensitive the equipment, the smaller the area of vulnerability will be (and the fewer times sags will cause the equipment to misoperate). The voltage sag performance for a given customer facility will depend on whether the customer is supplied from the transmission system or from the distribution system.

  • The microcontroller is an exciting new device in the field of electronics control. It is a complete computer control system on a single chip. microcontrollers include EPROM program memory, user RAM for storing program data, timer circuits, an instruction set, special function registers, power on reset, interrupts, low power consumption and a security bit for software protection. Some microcontrollers like the 16F818/9 devices include on board A to D converters.

  • In rapid-response situations, the ability of supercapacitors and batteries to provide power (W) over a short period of time is more important than their ability to provide energy (Wh) over a long period of time. Familiar examples are the starting of internal combustion engines, the protection of computers and telecommunications equipment against brief interruptions of mains power supply, the starting of electrical motors with high inrush currents, and the triggering of fuses.

  • This paper proposes an interactive control algorithm for seamless transfer of three-phase grid-connected converter between grid-tide mode and stand-alone mode. In order to archive a smooth transfer between two modes, the voltage controller and current controller are designed to generate the output voltage reference of PWM with no interrupted transition during islanding operation and grid connected operation.

  • The first sketches for “The Will to Power” were made in 1884, soon after the publication of the first three parts of “Thus Spake Zarathustra,” and thereafter, for four years, Nietzsche piled up notes. They were written at all the places he visited on his endless travels in search of health—at Nice, at Venice, at Sils-Maria in the Engadine (for long his favourite resort), at Cannobio, at Zürich, at Genoa, at Chur, at Leipzig.

  • What is the Prize, and who pays the Price? The desired and the desirable are often constellated through our ideas of what is undesired and undesirable, deeply knotted into our sense of self, our sense of where and how we fit into the world. These notions of desire form the backdrop to this powerful volume which examines the historical continuities and interruptions of heteronormativity in South African society.

  • The MMA8452Q is a smart, low-power, three-axis, capacitive, micromachined accelerometer with 12 bits of resolution. This accelerometer is packed with embedded functions with flexible user programmable options, configurable to two interrupt pins. Embedded interrupt functions allow for overall power savings relieving the host processor from continuously polling data.
