In HVT (High profile Technology), any voltage above 11 kilo-volts is recognized as within the high voltage range. It can be either alternating or direct current. Tastes industries are offered using this array of voltages from the national grid while many generates their own high voltage power using power generators. Elevated voltages usually are stepped down to some specific lower voltages, to operate their electrical machinery such as motors, heaters, HVAC systems, and others. Of those industries, regular checks have to be conducted by authorized personnel to evaluate the health of their equipment. Equipment tests are very crucial in determining the steadiness of a machine in order to avoid equipment breakdown and massive production losses. These tests also assist in determining if the newly purchased devices are worth, before installing it. Most manufacturers use hollywood testing to check the insulation with their equipment before supplying them with their customers.

The main advantages of applying hollywood insulation testing are generally looked down upon by a lot of industries, like a strategy of determining the conditionality of the electrical equipment. This is greatly related to the fact that much pressure and emphasis is definitely place on production activities on the worth of proactive repair of the apparatus. A dependable and effective insulation with an electrical machine is so very important because of its correct operation each time. Since insulation of apparatus degrades after a while, the respective electrical department for any industry must be regularly conducting regular check-ups for machines in their normal working schedule. This should be done to even low and medium voltage systems.

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

In-process testing

This can be the most rudimentry process which can be done even around the readily installed equipment, as long as it’s not at all running. This method requires the using a meggering instrument to try the insulation integrity in 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 point. Therefore, the dielectric withstanding voltage and insulation resistance in the coil can be determined.

Ancillary Equipment Testing

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

Generator Assembly Test

In such cases the generator is visually inspected. Cleaning is performed and the machine’s stability is also assessed. The heart beat in the machine is closely monitored utilizing a special display instrument. The device is also meggered for insulation resistance and dielectric withstanding voltage test.

One of many factors to consider in testing equipment are; voltage and right testing equipment. Which are more dependable results testing voltage ought to be adequate to effectively study the insulating resistance. However, it shouldn’t be too much to overstress the equipment insulation. The proper testing equipment which could effectively store results lets them be stored in a computer for archiving and analysis. This procedure saves some time to decreases the probability of error.
