In an electrical system, there are two ways to measure voltage: line-to-line voltage and line-to-neutral voltage. Here is the difference between the two: What is line to line voltage? The LL voltage is the electrical potential difference that exists between two phases of a three-phase or two-phase system. It is measured between two conductors (or phases) of …
Electrical equipment is commonly connected to single-phase, two-phase and three-phase systems with different voltages, it is very important to identify the number of phases to which the voltage refers, because there are cases in which there are equal voltages but different number of phases. For example, the case of the 220V voltage that in the …

Lumens and candela are units of measurement for lighting, but they measure different aspects of a lighting fixture. Lumens refers to the total amount of light that a lighting fixture emits, while candela refers to the amount of light emitted by a lighting fixture in a particular direction. In this article you will find the …
This calculator is used to convert BTU/hr to kW, you will also find the definitions, explanation and examples of conversion. Commonly this BTU/hr to kW ratio is used for air conditioning systems or heaters, the measurement is expressed in terms of how many BTUs per hour the product can add to or remove from the …
