Constant Voltage Transformer | Its Working & Application
Constant Voltage Transformer(CVT) provides a regulated output voltage by ferroresonance phenomenon when there is variation in supply voltage. We also call a CVT Ferroresonant Transformer.
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
Why is PT burden high Compared to CT burden?
The burden is the maximum load that we can connect to the secondary CT and PT. The burden of CT and PT are expressed in
What is CT Burden? CT Burden Formula
CT burden means the load connected to CT secondary. The load may be of the resistive type or of the inductive type. However, the load
