### What does a Compound-wound generator refer to?

A type of generator with both series and shunt field windings

### How is voltage regulation achieved in a DC Generator?

By adjusting the excitation or field current

### What is the purpose of parallel operation of DC generators?

To increase the efficiency of the generators

### Which factor is crucial for determining the efficiency of generators?

Ratio of output power to input power

### What is the purpose of the series field coils in a short-shunt compound generator?

To regulate the terminal voltage of the generator

### What is the main reason for connecting multiple smaller generators in parallel in a DC power plant, rather than using a single large generator?

To ensure continuity of service in case of a generator failure

### What is the relationship between the constant or rotational losses and the variable losses in a generator for maximum efficiency?

The constant or rotational losses should be made equal to the variable losses to achieve maximum efficiency

### What is the definition of voltage regulation in a DC generator?

The percentage rise in the terminal voltage of the generator when the load is removed

### Which of the following is a benefit of efficiently loading a generator in a DC power plant?

It reduces the electric power cost per kWh

To regulate the terminal voltage of the generator

### What is the primary advantage of parallel operation of generators?

Ability to perform routine or emergency operations while isolating affected generators

### Why might parallel operation of smaller generators be preferred over a single large unit?

A single large unit of desired capacity may not be available

### What is a potential consequence of paralleling a DC generator with reversed polarity?

Serious short-circuit and potential damage to the generator

AC generators

### What is the purpose of a compound-wound generator?

To improve voltage regulation
