Single Phase Transformers

[bctt tweet=”Information & Introduction to Transformer basics. Most transformers are ‘step down’ types. This means that the voltage coming out is less than the voltage going in…” username=”yeswayradio”]

Marine Induction Motor Servicing Tips

Tips for Servicing Marine & Land Based Induction Motors. Safety & Isolation of supply of induction motors. Taking a casual approach to electricity can prove fatal. This is especially true when we are talking about three-phase motors, as they operate in the UK & EU at 400 Volts Alternating Current Read more…

Star-Delta Starters

A  Star-Delta (or Wye-Delta)  starter is used in electrical engineering to start larger three phase motors, typically over 4 KW (5 HP). The Star-Delta starter is chosen, rather than the cheaper D.O.L (Direct On Line) for larger motors, because when a motor is started a surge current is generated for Read more…

Comparison of True Versus Reactive Power

 Comparison of True Versus Reactive Power When a  resistive load is connected, no phase shift is occurs between the voltage and current. The Power that is the  result of the resistive load  performs work in the circuit. This is      known as “true” power, and is measured in watts. By  comparison, an Read more…

Inductive Loads

Inductive Loads Inductive loads are loads from electrical equipment.  Electricity circulates through coiled or wound  wire. An inductor is a component which produces a magnetic field, when a current is passed through it. Examples of inductive loads include relays, motors, solenoids, & transformers. As a general rule, if an electrical Read more…

Resistive Loads

Resistive Loads Resistive loads are most often are found  in circuits where electricity  produces heat, light, or both forms of energy, Resistive loads do not produce movement. Examples of resistive loads include Kettles, Incandescent Bulbs, and Heaters.   (c) 2013 Craig Miles
