چکیده
Abstract A miniaturized analog load-checking relay protection test device is developed in this paper, which a high-precision wireless phase volt-ampere configured. This device, characterized by intelligence and ease of operation, realizes the detection transformation ratio, polarity, phase, etc. secondary wiring transformer smart substation merging unit conventional substation. It meets testing requirements substations, can bus differential protection, line various protections such as main differential.

An Improved Hadoop Data Load Balancing Algorithm
Data load balancing is one of the key problems of big data technology. As a big data application, Hadoop has had many successful applications. HDFS is Hadoop Distributed File System and has the load balancing procedure which can balance the storage load on each machine. However, this method cannot balance the overload rack preferentially, and so it is likely to cause the breakdown of overload m...
متن کاملAn improved test for phenylketonuria.
HENYLKETONURIA (phenylpyruvic oligophrenia) is a metabolic disorder first recognized by Foiling (1) approximately 25 years ago. He found that two mentally retarded children in. the same family excreted urine containing a substance which gave a green color with ferric chloride. This substance was identified as phenylpyruvic acid. It has subsequently been recognized that in phenylketonuria a bloc...
متن کاملTowards an improved sterility test.
The sterility test is generally recognized as a flawed test for its stated purpose. Since the original description in 1932, this test has generated controversy as to its role in product quality testing and in terms of means to improve the assay. As early as 1956 Bryce published an article describing the two critical limitations of this test (1). He put forward that the test was limited in that ...
متن کاملAn improved Test Control Architecture and Test Control Expansion for Core-Based System Chips
This paper presents improvement of a core-based chip’s test control architecture that uses Std IEEE 1149.1 TAP to access core level register Test Control Blocks (TCB). We show enhancements for the register TCB, to improve its test coverage, to enable IEEE 1149.1 compliant RUNBIST and to optimize chip level TCB access. In addition, Test Control Expansion (TCE) is presented. TCE automatically val...
متن کاملAn Improved Under-Frequency Load Shedding Scheme in Distribution Networks with Distributed Generation
When a distribution network consisting of Distributed Generations (DGs) is disconnected from upstream network, the system may be exposed to severe power imbalance. In order to prevent the damage of power plants, frequency relays operate and remove DGs from the network. In contrast to traditional methods, the main objective in new methods is to keep DG units in service in the islanded distributi...
