Linear Variable Differential Transformer (LVDT)

Tamunofiniarisa March 27, 2018 Educational, Electrical Education 0

What is an LVDT? LVDT is an acronym for Linear Variable Differential Transformer. It is a common type of electromechanical transducer that can convert the rectilinear motion of an object to which it is coupled mechanically into a corresponding electrical signal. LVDT linear position sensors are readily available that can measure movements as small as a few millionths of an inch up to several ... »

PRIMAVERA P6 PROGRESS LINE

Tamunofiniarisa March 7, 2018 Project Management Education 0

PRIMAVERA P6 PROGRESS LINE If you are looking for a real quick way to spot trouble in a project, the progress line is a vertical plot that provides the highest level view of schedule progress. Yes, it is a simple visual monitor for the project displaying exactly where you are ahead, behind, or on schedule. It’s great, in particular, for large projects where schedule discrepancy may not be easy to ... »

Three-phase Y and Delta Configurations | Polyphase AC Circuits

Tamunofiniarisa July 17, 2017 Blog, Electrical Education 0

Initially we explored the idea of three-phase power systems by connecting three voltage sources together in what is commonly known as the “Y” (or “star”) configuration. This configuration of voltage sources is characterized by a common connection point joining one side of each source. (Figure below) Three-phase “Y” connection ... »

Vector Group of Transformer

Tamunofiniarisa June 19, 2017 Blog, Electrical Education 0

Vector Group of Transformer Introduction: Three phase transformer consists of three sets of primary windings, one for each phase, and three sets of secondary windings wound on the same iron core. Separate single-phase transformers can be used and externally interconnected to yield the same results as a 3-phase unit. The primary windings are connected in one of several ways. The two most common con... »

Control of Synchronous Generators with Droop and Cross-Current Compensation.

Tamunofiniarisa June 13, 2017 Blog, Electrical Education 0

Control of Synchronous Generators with Droop and Cross-Current Compensation. Details Written by Stefanos Spanopoulos, MIET The excitation of a synchronous generator is usually done by an AVR (Automatic Voltage Regulator) that uses generator voltage and/or current as inputs in order to control its output to a pre-set value. AVRs include different control modes to optimise performance dependi... »
