The term “critical point” is sometimes used to denote specifically the vapour-liquid critical point of a material. The vapour-liquid point denotes the condition above which distinct liquid and gas phases so not exist. The project, the construction of critical temperature measuring instrument is aimed at measuring the critical point substances thereby obtaining its liquid-vapour critical temperature and pressure for a selected substance.

Generally, a survey of previous equipment used by the various researchers was found to be very complicated and expensive and such equipment cannot be afforded by local Nigerian researchers due to cost. It was this that necessitated us to come up with a locally made equipment to detect the breakdown of insulators due to excess voltage in practical system. The construction is simple, cheap and reliable.

Automatic Voltage Regulator is a device that serves as intermediary to electrical/electronic equipment and its major purposes is to prevent malfunctions or damage to electrical equipments. And another major purpose of this AVR is to regulate varying voltage level automatically to a constant voltage. Having AVR as an intermediary device, it will motivate you in a such a way that you will not be having biasing mind in powering any device.

Another feature attached to the electrical design, is the ‘LOAD CHART AND BALANCING TABLE”. This feature explains how loads are distributed and balanced in the Distribution Board of the structure design electrically by the electrical engineer. Another important feature of the electrical design, is the FUSE ARRANGEMENT. This feature is so important to the design because it specifically stipulates the ratings of each fuse and the circuit coming into it from the designed structure. It shows whe... read more

With square waves, the RMS and Average value are identical! An Ac meter calibrated to accurately read RMS voltage or current on a pure sine wave will not give the proper the proper value while indicating the magnitude of anything other than a perfect sine wave. This includes triangle waves, square waves, or kind of distorted sine wave. With harmonics becoming an ever- present phenomenon in large Ac power systems,. This matter of accurate RMS measurement is no small matter.
