Why DC Series Motor has High Starting Torque?
DC series motor is widely used for high inertia loads like Hoists, cranes, Rotary Kiln, and Traction that require high initial torque at the start.
Machines
An electrical machine converts mechanical energy into electrical energy or vice versa. The transformer is also an electrical machine which transform the voltage without changing the frequency. We will discuss about the;
- DC Motor
- DC generator
- Induction Motor
- Transformer
- Electrical drives
- Alternator or synchronous generator
Can Protection CT be used as Metering CT & Vice Versa?
We can not use the protection class CT in place of metering CT & vice versa. Protection class CT and metering class CT are used
Percentage Impedance of Transformer & Its Calculation

What is a Transformer? Definition & Meaning
A transformer is a static piece of equipment that does not have any moving parts in it. The transformer transforms higher voltage to lower voltage
Difference between Power Transformer & Distribution Transformer
This article describes the difference between a power transformer & distribution transformer. Power transformers and Distribution transformers are widely used in power systems for step-up and
Why Single Phase Induction Motor is not Self-Starting?
The main reason why a single-phase induction motor is not self-starting is that it produces a revolving magnetic field and not a rotating magnetic field.
Troubleshooting of Star-Delta Starter
