WORKERS ACTIVITY MONITORING AND ANALYZING WITH MINIATURE WEARABLE SUPER ACTIVE RF SENSOR USING LOCAL RF NET WORK AND CENTRAL MONITOR STATION IN REAL TIME.

With advancement in technology and science electronics have been getting smaller and smaller, which enables researchers and scientist to weave the electronics and interconnections into human body. This new technology enables to establish a new concept called electronic workers activity monitoring which allows cost-effective and efficient solutions for monitoring efficiency of workers in th ....etc

An accurate electric current transducer is a key component of any power system instrumentation. To measure currents power stations and substations conventionally employ inductive type current transformers with core and windings. For high voltage applications, porcelain insulators and oil-impregnated materials have to be used to produce insulation between the primary bus and the secondary windings. The insulation structure has to be designed carefully to avoid electric field stresses, which could eventually cause insulation breakdo ....etc

ABSTRACT:
When we think about warehouses of today’s industries, the first thought that pops is “THE DARKNESS”. This paper deals with the automatic switching ON and OFF of lights in warehouses using micro processors and sensors. The circuit consists of two optical sensors, counters, phototransistors and relay switches. One optical sensor is installed at the entry door and another optical sensor is installed at the exit door of the ware house. The receiver sections of the sensors ....etc

How to use a mains transformer (for instance 110-230 Volt and 50-60 Hz) in an electronic project. Do's and dont's with mains transformers in home brew electronics.

Saturation of the core means that the core gets more or less permanenty magnetised. In that case the magnetic field is not built up (and decreased) quickly enough (50 Hz -60 Hz), the permanent field acts as a sort of brake for quick magnetic changes and the power cannot be well transferred from the primary to the secundary coil. The core gets heated up more or less, it gives lo ....etc

Simulation & Modeling of “Sen Transformer ”
Introduction
Issues, Power Industry is Facing Today
1. Demand for electrical energy is increasing.
2. “Free Flow” makes particular transmission lines overloaded.
3. Construction of new transmission lines has become increasingly difficult and expensive.
4. Energy needs to be transported from the generating point to the end user along the most desirable path
Principles of Power Flow in a Transmission Line
Power flow ....etc
