In HVT (Hollywood Technology), any voltage above 11 kilo-volts is considered to be within the high voltage range. It could be either alternating or direct current. Most industries are supplied with this particular variety of voltages in the national grid while many generates their unique high profile power using generators. These high voltages usually are stepped right down to some specific lower voltages, to operate their electrical machinery including motors, heaters, HVAC systems, and others. For these industries, regular checks has to be conducted by authorized personnel to evaluate the healthiness of their equipment. Equipment testing is very crucial in determining the steadiness of your machine to be able to avoid equipment breakdown and large production losses. These tests also aid in determining if a newly purchased products are worth, before setting it up. Most manufacturers use high profile testing to check the insulation of their equipment before supplying them on their customers.

The main advantages of applying high voltage insulation testing are likely to be looked down upon by a lot of industries, as being a strategy of learning the conditionality with their electrical equipment. This is greatly related to the fact much pressure and emphasis is definitely placed on production activities on the expense of proactive maintenance of the equipment. A reliable and effective insulation to have an electrical machine is of utmost importance for the correct operation whenever. Since insulation of apparatus degrades with time, the respective electrical department for almost any industry must be regularly conducting regular check-ups for machines within their normal working schedule. Do that to even low and medium voltage systems.

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

In-process testing

Here is the most basic process that may be done even about the readily installed equipment, provided that it is not running. This procedure requires the usage of a meggering instrument to evaluate the insulation integrity in the coils before it’s linked to phases, neutral, and earth. Occasionally, a multimeter can 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 when the components are interconnected or separated.

Generator Assembly Test

In such cases the generator is visually inspected. Cleaning is completed and the machine’s stability can be assessed. The heart beat from the machine is closely monitored by using a special display instrument. The device is additionally meggered for insulation resistance and dielectric withstanding voltage test.

One of the considerations in testing equipment are; voltage and right testing equipment. Which are more dependable results testing voltage should be adequate to effectively look at the insulating resistance. However, it shouldn’t be too much to overstress the equipment insulation. The appropriate testing equipment which may effectively store results lets them be held in some type of computer for archiving and analysis. This action saves time and cuts down on likelihood of error.
