One of the most important aspects in building and construction is ensuring that all the essential appliances are properly installed in the structure. One of the most important aspects in construction is power thus all measures must be taken in order do the proper power installation. During or when doing electric installation having knowledge of the alternating current is very important as it is one of the importance of having a safe electric installation in the structure. Alternating current (ac) is current that reverses direction after a certain period. This is very different from Direct current (dc) as direct current flows in only one direction.

Power is delivered to homes or a business in the form of Alternating Current thus is the form in which power is delivered to a structure. The power cable or wires used in delivering this alternating current should be carefully selected so that the wires can carry both the radio and the audio signals. In order for the power cable to deliver sufficient power to the system it is very important to calculate the amount of voltage in the alternating current so that to know the types of materials to be used in the system. The main aim of the system in order to have sufficient power delivery is the recovery of the modulated information on the AC signal.

The most commonly used power cables are the high voltage power cables. There are different systems of calculating the alternating current voltage and there is what determines the kind of power cables to be used. An example of the systems used to calculate the AC voltage is the AC resonant test system which is mainly used during high voltage routines. It is also mainly used in output of the AC voltage. These systems are most practical when doing field testing and also in large capacitance loads. Another method for testing the AC voltage is the use of T 22/1 set. It is a portable set test which mainly consists of two units that are separate. There is the control unit and also the unit for high voltage tests. The division of the two enables the test to be done by the operator without any kind of transport.

The power cable ac voltage test is thus essential for correct and safe power supply. The power cable should be a high voltage power cable as it mostly delivered alternating current through a transformer which increases or decreases the power voltage. Generation of electricity via the three phase system is very common and a system where four wires are used is most common during utilization power.
