Neutral current, unbalance system and neutral earth voltagePrasad Gore
Neutral current flows in a star-connected system with an unbalanced load. This neutral current can overload and potentially fail the neutral conductor if not monitored. According to symmetrical component theory developed by Fortescue, any unbalanced three-phase system can be resolved into three balanced components - positive, negative, and zero sequences. The zero sequence component represents one-third of the neutral or common mode current in the system. With an unbalanced load, the neutral or common mode voltage rises compared to earth potential, which can cause issues for equipment.
Load Balancing in Parallel and Distributed DatabaseMd. Shamsur Rahim
This document discusses load balancing techniques in distributed database systems. It describes different types of parallelism including inter-query, intra-query, intra-operation, and inter-operation parallelism. It also discusses problems that can occur with parallel execution such as initialization, interference, and skew. The document then focuses on techniques for load balancing within operators and between operators, including adaptive and specialized techniques. It describes how activations, activation queues, and threads can be used to improve load balancing in shared-memory systems.
The document discusses balancing of rotating and reciprocating masses. It describes static and dynamic balancing, where static balancing ensures the center of gravity remains stationary during rotation and dynamic balancing ensures the resultant moments are equal to zero. Types of balancing discussed include balancing a single rotating mass with one or two masses in the same or different planes, as well as balancing multiple masses in the same or different planes. Examples provided calculate the magnitude and position of balancing masses given masses, radii of rotation, and angular positions of unbalanced masses.
Load balancing distributes network traffic across multiple servers to optimize resource utilization, maximize throughput, minimize response time, and avoid overload. It improves availability and reliability. In Windows Server 2003, Network Load Balancing allows multiple servers to be grouped together and appear as a single virtual server to clients. Requests are distributed to servers using round-robin DNS or a hardware load balancer which rewrites requests and forwards them to cluster nodes based on performance metrics. Servers detect failures and new additions to ensure high availability.
This document summarizes the history of cigarettes and their harmful effects. It notes that cigarettes were first mass produced in the late 1800s and contained over 4000 chemicals, including 60 carcinogens. The summary describes some of the major health risks of smoking such as heart disease, cancer, and reduced lung function. It also mentions that smoking can harm fetal development and increase risks during pregnancy. The document aims to inform people about the long history of cigarette use and their significant health consequences.
This document discusses load balancing, which is a technique for distributing work across multiple computing resources like CPUs, disk drives, and network links. The goals of load balancing are to maximize resource utilization, throughput, and response time while avoiding overloads and crashes. Static load balancing involves preset mappings, while dynamic load balancing distributes workload in real-time. Common load balancing algorithms are round robin, least connections, and response time-based. Server load balancing distributes client requests to multiple backend servers and can operate in centralized or distributed architectures using network address translation or direct routing.
