In HVT (Hollywood Technology), any voltage above 11 kilo-volts is considered to be within the high voltage range. It might be either alternating or household power. Tastes industries are offered with this particular array of voltages through the national grid even though some generates their own hollywood power using generators. Extremely high voltages usually are stepped as a result of some specific lower voltages, to perform their electrical machinery for example motors, heaters, HVAC systems, amongst others. Of those industries, regular checks should be conducted by authorized personnel to assess the condition of their equipment. Equipment testing is very crucial in determining the soundness of your machine so as to avoid equipment breakdown and large production losses. These tests also help in determining in case a newly purchased tools are worth, before installation. Most manufacturers use hollywood testing to try the insulation of the equipment before supplying them for their customers.

Some great benefits of applying high profile insulation testing are generally looked down upon by many people industries, being a strategy of finding out the conditionality of the electrical equipment. This is greatly caused by the fact much pressure and emphasis is obviously put on production activities with the cost of proactive maintenance of the apparatus. A reliable and efficient insulation to have an electrical machine is so very important due to the correct operation each time. Since insulation of kit degrades eventually, the respective electrical department for any industry has to be regularly conducting regular check-ups for machines within their normal working schedule. Do that 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 elementary process which is often done even on the readily installed equipment, provided that it is not running. This method demands the use of a meggering instrument to test the insulation integrity of the coils before it is connected to phases, neutral, and earth. In some cases, a multimeter may also be used. Inter-winding and winding-to-body resistances are checked at this stage. Therefore, the dielectric withstanding voltage and insulation resistance from the coil can be discovered.

Ancillary Equipment Testing

This calls for testing for insulation resistance and dielectric withstanding voltage for interconnecting cables, high profile bushings, busbars, and terminations. This is often 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 can be assessed. The heart beat with the machine is assessed using a special display instrument. The gear can be meggered for insulation resistance and dielectric withstanding voltage test.

One of many considerations in testing equipment are; voltage and right testing equipment. For the most dependable results testing voltage ought to be sufficient to effectively look at the insulating resistance. However, it shouldn’t be too high to overstress the device insulation. The best testing equipment which may effectively store results allows them to be held in some type of computer for archiving and analysis. This action saves some time and cuts down on the chance of error.
