In HVT (High Voltage Technology), any voltage above 11 kilo-volts is considered to be within the hollywood range. It can either be alternating or direct current. Majority of industries are offered using this type of range of voltages from the national grid while many generates their unique high profile power using power generators. Elevated voltages are generally stepped right down to some specific lower voltages, to own their electrical machinery like motors, heaters, HVAC systems, and others. Because of these industries, regular checks should be conducted by authorized personnel to gauge the fitness of their equipment. Equipment exams are very crucial in determining the steadiness of your machine so as to avoid equipment breakdown and large production losses. These tests also aid in determining if a newly purchased devices are worth, before installing it. Most manufacturers use hollywood testing to evaluate the insulation of their equipment before giving them for their customers.

The benefits of applying high profile insulation testing are generally looked down upon by many industries, like a means of determining the conditionality with their electrical equipment. This is often greatly related to the fact that much pressure and emphasis is always place on production activities in the tariff of proactive maintenance of the apparatus. The best and effective insulation to have an electrical machine is so very important for the correct operation each time. Since insulation of apparatus degrades as time passes, the respective electrical department for any industry should be regularly conducting regular check-ups for machines in their normal working schedule. Do that to even low and medium voltage systems.

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

In-process testing

This can be the most basic process which can be done even for the readily installed equipment, as long as it is not running. This procedure requires the use of a meggering instrument to evaluate the insulation integrity from the coils prior to it being connected to phases, neutral, and earth. In some instances, a multimeter could also be used. Inter-winding and winding-to-body resistances are checked during this period. Therefore, the dielectric withstanding voltage and insulation resistance with the coil can be discovered.

Ancillary Equipment Testing

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

Generator Assembly Test

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

On the list of factors to consider in testing equipment are; voltage and right testing equipment. For dependable results testing voltage needs to be high enough to effectively appraise the insulating resistance. However, it should not be way too high to overstress the device insulation. The appropriate testing equipment which could effectively store results enables them to be kept in a computer for archiving and analysis. This action saves some time to cuts down on the risk of error.
