Pulsed Power

Pulsed Power

Pulsed power is the science and technology of accumulating energy over a relatively long period of time and releasing it very quickly, thus increasing the instantaneous power.

Rogowski Coil Frequency

Rogowski Coil

A Rogowski coil, named after Walter Rogowski, is an electrical device for measuring alternating current (AC) or high speed current pulses. It consists of a helical coil of wire with the lead from one end returning through the centre of the coil to the other end, so that both terminals are at the same end of the coil.

Current Transformer Electric

Electricity Meters

Electronic metering of electrical energy requires the independent sensing of both load current and supply voltage, continuous multiplication of these two quantities to produce instantaneous load power and the integration of varying load power with respect to time to derive accumulated energy usage.

Paralleling Current Transformers

Current Transformers Object

This page discusses the issues of using current transformers (CTs) in parallel. Circuits with multiple conductors (common on high current circuits): Measuring Parallel Conductors. To add the power and energy readings of multiple branch circuits and measure them with one WattNode.

Foundation Pneumatic

Pneumatic Air

Pneumatic is a theory or knowledge of moving air, air equilibrium conditions and the conditions of equilibrium. Greek derived word pneumatic "pneuma" which means "breath" or "air". So the air-filled or pneumatic means is driven by compressed air.

History Wind Energy

Wind Plant

Wind can be used to do work. The kinetic energy of the wind can be changed into other forms of energy, either mechanical energy or electrical energy. When a boat lifts a sail, it is using wind energy to push it through the water. This is one form of work.

Process Landfill Gas

Landfill Gas Process

"Landfill gas" is not the same thing as "natural gas" or "methane." They are three separate terms which mean different things. They should not be used interchangeably. The term "landfill methane" is deceiving as it's usually used to imply that landfill gas is simply methane.

Crops Make Biomass

Crops

While displacing relatively small percentages of fossil fuel use with biomass energy crops may not sound like much, it is very significant when recognizing the tremendous size of electricity generation facilities.

Rice Husk Make Biomass

Rice Husk

If we go back to history, we will realize that briquetting technology was only accessed in Europe and the United States. However, over the years, other countries have joined in with Japan taking part in the invention of screw press technology, one of the technologies highly used in the briquetting processes.

Formula Current Voltage Solar Cell

Current Voltage Solar Cell

Materials with a pn -junction show a nonlinear, rectifying characteristic, since it is much easier to move electrons from the electrode through the p -type region and through the junction than from the n -type region over the junction barrier into the p -type region.

Formula Panel Solar

Panel Solar

To understand the electronic behavior of a solar cell, it is useful to create a model which is electrically equivalent, and is based on discrete electrical components whose behavior is well known.

Work Anaerobic Digestion

Plan Anaerobic Digestion

Anaerobic digestion is a series of processes in which microorganisms break down biodegradable material in the absence of oxygen. It is used for industrial or domestic purposes to manage waste and/or to release energy.

AC generator

AC Generator Object

In electricity generation, an electric generator is a device that converts mechanical energy to electrical energy. A generator forces electric charge (usually carried by electrons) to flow through an external electrical circuit.

Direct Current

Types of Current

Direct current (DC) is the unidirectional flow of electric charge. Direct current is produced by sources such as batteries, thermocouples, solar cells, and commutator-type electric machines of the dynamo type.

Alternating Current

Types of Current

In alternating current (AC, also ac), the movement of electric charge periodically reverses direction. In direct current (DC, also dc), the flow of electric charge is only in one direction.

Rotor Voltage Control

Rotor Voltage Object

Inverted rotor induction motor has additional rotor rings. These rings are used to make connection for the rotor measurement coils. These coils have been used to investigate induced voltage on the rotor.

Torque Strap

Torque Strap

If you've ever had an engine mount break upon hard acceleration, you may be familiar with the damage it can do. The fan can hit the shroud, and the air cleaner can come up and smack the hood.

Traction Motor Structure

Traction Motor Object

Traction motor refers to an electric motor providing the primary rotational torque of a machine, usually for conversion into linear motion (traction).

Motor Stepper Table

Motor Stepper Object

Permanent magnet stepper motors work on the interaction between the rotor magnetic flux with the magnetic force raised by the current flowing in the stator winding.

Servo Motor

Motor Servo

Servo motor is a motor with a closed feedback system in which the position of the motor will be communicated back to the control circuit in the servo motors.
