In HVT (Hollywood Technology), any voltage above 11 kilo-volts is recognized as in the high profile range. It can be either alternating or direct current. Most of industries are provided with this particular variety of voltages from the national grid while many generates their unique hollywood power using power generators. These high voltages are often stepped right down to some specific lower voltages, to run their electrical machinery including motors, heaters, HVAC systems, amongst others. Because of these industries, regular checks must be conducted by authorized personnel to guage the fitness of their equipment. Equipment tests are very essential in determining the soundness of an machine in order to avoid equipment breakdown and big production losses. These tests also help in determining if your newly purchased products are worth, before setting it up. Most manufacturers use high profile testing to try the insulation with their equipment before giving them to their customers.

The advantages of applying high voltage insulation testing are often looked down upon by many industries, like a strategy of discovering the conditionality with their electrical equipment. This could be greatly attributed to the fact that much pressure and emphasis is obviously place on production activities on the tariff of proactive upkeep of the equipment. The best and effective insulation for an electrical machine is so very important due to the correct operation every time. Since insulation of kit degrades after a while, the respective electrical department for virtually any industry should be regularly conducting regular check-ups for machines as part of their normal working schedule. Make this happen to even low and medium voltage systems.

In many instances, a four stage process is followed. The stages are briefly described below:

In-process testing

This is actually the most basic process which is often done even for the readily installed equipment, so long as it is not running. This process necessitates the using a meggering instrument to evaluate the insulation integrity from the coils before it’s linked to phases, neutral, and earth. In some instances, a multimeter could also be used. Inter-winding and winding-to-body resistances are checked at this stage. Therefore, the dielectric withstanding voltage and insulation resistance with the coil can be discovered.

Ancillary Equipment Testing

This calls for testing for insulation resistance and dielectric withstanding voltage for interconnecting cables, hollywood bushings, busbars, and terminations. This can be conducted in the event the components are interconnected or separated.

Generator Assembly Test

In this instance the generator is visually inspected. Cleaning is completed as well as the machine’s stability can be assessed. The pulse of the machine is observed at close range by using a special display instrument. The apparatus is additionally meggered for insulation resistance and dielectric withstanding voltage test.

One of the things to consider in testing equipment are; voltage and right testing equipment. Which are more dependable results testing voltage must be enough to effectively study the insulating resistance. However, it should not be way too high to overstress the apparatus insulation. The right testing equipment which could effectively store results enables them to be held in some type of computer for archiving and analysis. This action saves time and decreases the risk of error.
