    In HVT (High profile Technology), any voltage above 11 kilo-volts is known as within the high voltage range. It could be either alternating or dc. Most industries are provided using this selection of voltages from the national grid while some generates their unique hollywood power using generators. Elevated voltages are usually stepped into some specific lower voltages, to perform their electrical machinery including motors, heaters, HVAC systems, amongst others. Because of these industries, regular checks have to be conducted by authorized personnel to guage the health of their equipment. Equipment tests are very essential in determining the steadiness of a machine so as to avoid equipment breakdown and large production losses. These tests also assist in determining if the newly purchased equipment is worth, before installing it. Most manufacturers use hollywood testing to test the insulation of their equipment before giving them on their customers.

    The main advantages of applying high profile insulation testing are likely to be looked down upon by a lot of industries, like a strategy of determining the conditionality of the electrical equipment. This is often greatly attributed to the fact that much pressure and emphasis is always put on production activities with the cost of proactive maintenance of the gear. A reliable and efficient insulation to have an electrical machine is very important for its correct operation every time. Since insulation of kit degrades with time, the respective electrical department for just about any industry have to be regularly conducting regular check-ups for machines in their normal working schedule. Make this happen to even low and medium voltage systems.

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

    In-process testing

    This is actually the simplest process that may be done even for the readily installed equipment, as long as it is not running. This method demands the use of a meggering instrument to evaluate the insulation integrity in the coils before it’s linked to phases, neutral, and earth. Occasionally, a multimeter could 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 determined.

    Ancillary Equipment Testing

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

    Generator Assembly Test

    In this instance the generator is visually inspected. Cleaning is done and the machine’s stability can be assessed. The heartbeat in the machine is observed at close range employing a special display instrument. The gear can be meggered for insulation resistance and dielectric withstanding voltage test.

    On the list of considerations in testing equipment are; voltage and right testing equipment. For the best dependable results testing voltage needs to be sufficient to effectively measure the insulating resistance. However, it shouldn’t be too high to overstress the equipment insulation. The right testing equipment which can effectively store results lets them be kept in your personal computer for archiving and analysis. This procedure saves serious amounts of decreases the risk of error.
