To convert horsepower (Hp) to kilovolt-amperes (kVA), multiply the horsepower by 0.746 and divide by the power factor (PF). This helps in determining the equivalent kVA for a given motor or generator.

The **Hp to kVA Calculator** is a tool used to convert horsepower. It is particularly used to rate engines and motors, into kilovolt-amperes (kVA), which measures apparent power in electrical systems. This conversion is essential in selecting and sizing generators and transformers, particularly in industrial applications.

Different factors, like power factor and efficiency, influence the kVA value required to handle a certain horsepower load. Therefore, knowing this conversion helps ensure that the generator or power supply can effectively meet the power demands of the equipment, avoiding overloads and ensuring optimal performance.

**Formula:**

$$kVA=\frac{(Hp\times 0.746)}{P\mathrm{F}}$$

Variable | Description |
---|---|

$kVA$ | Apparent Power in kilovolt-amperes |

$Hp$ | Horsepower of the motor |

$PF$ | Power Factor (typically ranges from 0 to 1) |

**Solved Calculations:**

**Example 1:**

Convert 10 Hp to kVA with a power factor of 0.85.

Step | Calculation |
---|---|

1. | $kVA = \frac{(10 \times 0.746)}{0.85}$ |

2. | $kVA = \frac{7.46}{0.85}$ |

3. | $kVA = 8.776$ |

**Answer: 8.78 kVA**

**Example 2:**

Convert 25 Hp to kVA with a power factor of 0.9.

Step | Calculation |
---|---|

1. | $kVA = \frac{(25 \times 0.746)}{0.9}$ |

2. | $kVA = \frac{18.65}{0.9}$ |

3. | $kVA = 20.72$ |

**Answer: 20.72 kVA**
