In HVT (High profile Technology), any voltage above 11 kilo-volts is known as from the high voltage range. It may either be alternating or dc. Tastes industries are provided using this variety of voltages from your national grid while some generates their own hollywood power using generators. Extremely high voltages are generally stepped into some specific lower voltages, to operate their electrical machinery for example motors, heaters, HVAC systems, and others. Because of these industries, regular checks has to be conducted by authorized personnel to evaluate the healthiness of their equipment. Equipment exams are very essential in determining the soundness of your machine to be able to avoid equipment breakdown and massive production losses. These tests also assist in determining if a newly purchased tools are worth, before installing it. Most manufacturers use high profile testing to evaluate the insulation with their equipment before giving them for their customers.

Some great benefits of applying high profile insulation testing are usually looked down upon by so many industries, like a means of determining the conditionality of these electrical equipment. This could be greatly caused by the truth that much pressure and emphasis is always placed on production activities with the worth of proactive repair off the device. A dependable and effective insulation to have an electrical machine is very important for the correct operation every time. Since insulation of equipment degrades after a while, the respective electrical department for almost any industry have to be regularly conducting regular check-ups for machines as part of their normal working schedule. This should be done 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

Here is the most basic process that may be done even around the readily installed equipment, providing that it isn’t running. This technique involves the use of a meggering instrument to try the insulation integrity in the coils before it is attached to phases, neutral, and earth. Sometimes, a multimeter doubles. Inter-winding and winding-to-body resistances are checked at this time. Therefore, the dielectric withstanding voltage and insulation resistance with the coil can be established.

Ancillary Equipment Testing

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

Generator Assembly Test

In this instance the generator is visually inspected. Cleaning is done and also the machine’s stability is additionally assessed. The heartbeat with the machine is assessed employing a special display instrument. The device is also 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 must be high enough to effectively study the insulating resistance. However, it should not be too much to overstress the equipment insulation. The appropriate testing equipment that may effectively store results lets them be held in a computer for archiving and analysis. This process saves some time to cuts down on the likelihood of error.
