In HVT (Hollywood Technology), any voltage above 11 kilo-volts is recognized as within the high voltage range. It can be either alternating or household power. Most industries are offered using this range of voltages through the national grid while some generates their unique hollywood power using power generators. Extremely high voltages are generally stepped down to some specific lower voltages, to perform their electrical machinery such as motors, heaters, HVAC systems, and others. For these industries, regular checks has to be conducted by authorized personnel to gauge the fitness of their equipment. Equipment exams are very essential in determining the soundness of your machine so as to avoid equipment breakdown and big production losses. These tests also assist in determining in case a newly purchased tools are worth, before setting it up. Most manufacturers use high profile testing to test the insulation of their equipment before supplying them on their customers.

The main advantages of applying hollywood insulation testing are often looked down upon by a lot of industries, as being a technique of learning the conditionality of these electrical equipment. This could be greatly related to the truth that much pressure and emphasis is definitely wear production activities with the expense of proactive upkeep of the equipment. A dependable and effective insulation on an electrical machine is of utmost importance due to the correct operation each time. Since insulation of apparatus degrades after a while, the respective electrical department for just about any industry should be regularly conducting regular check-ups for machines within their normal working schedule. Make this happen to even low and medium voltage systems.

Generally, a four stage process is followed. The stages are briefly described below:

In-process testing

This is the most elementary process which can be done even about the readily installed equipment, as long as it is not running. This technique requires the use of a meggering instrument to test the insulation integrity from the coils before it is associated with phases, neutral, and earth. Occasionally, a multimeter may also be used. Inter-winding and winding-to-body resistances are checked at this point. Therefore, the dielectric withstanding voltage and insulation resistance of the coil can be discovered.

Ancillary Equipment Testing

This implies testing for insulation resistance and dielectric withstanding voltage for interconnecting cables, high profile bushings, busbars, and terminations. This can be conducted when the components are interconnected or separated.

Generator Assembly Test

In such cases the generator is visually inspected. Cleaning is done along with the machine’s stability can also be assessed. The pulse from the machine is closely monitored employing a special display instrument. The equipment can be meggered for insulation resistance and dielectric withstanding voltage test.

One of the a few in testing equipment are; voltage and right testing equipment. For dependable results testing voltage needs to be enough to effectively study the insulating resistance. However, it should not be excessive to overstress the apparatus insulation. The best testing equipment that may effectively store results enables them to be stored in a computer for archiving and analysis. This process saves some time to decreases the risk of error.
