Plugged it in and that god awful fan spooled up. If the panel have total load of kVA, considering a Demand factor . Maximum Demand of whole System=70 KW; So Diversity factor of The.
Demand factors and diversity factors are used in design. For example, the sum of the connected loads supplied by a feeder is multiplied by the demand factor to determine the load for which the feeder must be sized. This load is termed the maximum demand of the feeder. The sum of the maximum demand loads for a number of sub feeders divided by the diversity factor for the sub feeders will give the maximum demand load to be supplied by the feeder from which the sub feeders are derived.

The estimated electrical demand for all feeders served directly from the service entrance is calculated by multiplying the total connected loads by their demand factors and then adding all of these together. This sum is divided by the diversity factor frequently assumed to be unity to calculate the service entrance demand which is used to determine ampacity requirements for the service entrance conductors. When used Diversity and Demand Factor in an electrical design it should be applied as follows, the sum of the connected loads supplied by a feeder-circuit can be multiplied by the demand factor to determine the load used to size the components of the system.
The sum of the maximum demand loads for two or more feeders is divided by the diversity factor for the feeders to derive the maximum demand load. Calculate Size of Transformer having following details: Higher the values of load factor and diversity factors, lower will be the overall cost per unit generated. The capital cost of the power station depends upon the capacity of the power station.
Lower the maximum demand of the power station, the lower is the capacity required and therefore lower is the capital cost of the plant. With a given number of consumers the higher the diversity factor of their loads, the smaller will be the capacity of the plant required and consequently the fixed charges due to capital investment will be much reduced.

Christians, the church and the Bible seem to be out of step with modern attitudes towards homosexuality. And there is growing hostility towards those who hold a different view. So is God homophobic? And what do we say, and how do we relate to to both Christians and non Christians who experience same-sex attraction. In this short, simple book, Sam Allberry wants to help confused Christians understand what God has said about these questions in the scriptures, and offers a positive and liberating way forward through the debate.
Yet many who sit next to us in the pew at church fit that description, says author Wesley Hill. Weaving together reflections from his own life and the lives of other Christians, such as Henri Nouwen and Gerard Manley Hopkins, Hill offers a fresh perspective on these questions. The world is polarizing over religion—or at the very least our culture is polarizing over religion.
Attempting to find a way forward, Keller suggests that both believers and skeptics look at doubt in a whole new way. Parts of the Transformer Conservator The conservator conserves the transformer oil. It is an airtight, metallic, cylindrical drum that is fitted above the transformer.
The conservator tank is vented to the atmosphere at the top, and the normal oil level is approximately in the middle of the conservator to allow the oil to expand and contract as the temperature varies.How to convert KVA TO KW(HINDI)
The conservator is connected to the main tank inside the transformer, which is completely filled with transformer oil through a pipeline. Breather Breather The breather controls the moisture level in the transformer. Moisture can arise when temperature variations cause expansion and contraction of the insulating oil, which then causes the pressure to change inside the conservator.

Pressure changes are balanced by a flow of atmospheric air in and out of the conservator, which is how moisture can enter the system. If the insulating oil encounters moisture, it can affect the paper insulation or may even lead to internal faults.
Therefore, it is necessary that the air entering the tank is moisture-free. The transformer's breather is a cylindrical container that is filled with silica gel.
When the atmospheric air passes through the silica gel of the breather, the air's moisture is absorbed by the silica crystals. The breather acts like an air filter for the transformer and controls the moisture level inside a transformer. It is connected to the end of breather pipe. Tap Changer Tap Changer The output voltage of transformers vary according to its input voltage and the load.

During loaded conditions, the voltage on the output terminal decreases, whereas during off-load conditions the output voltage increases. In order to balance the voltage variations, tap changers are used. Tap changers can be either on-load tap changers or off-load tap changers. In an on-load tap changer, the tapping can be changed without isolating the transformer from the supply. In an off-load tap changer, it is done after disconnecting the transformer.

Automatic tap changers are also available. Cooling Tubes Cooling tubes are used to cool the transformer oil. The transformer oil is circulated through the cooling tubes.
