There have been power interruptions during the test time for switches leading to considerable loss in terms of time and resources. For example, during the two times power was interrupted the switches, which were currently undergoing tests, were discarded.
It translated to loss on the timing side as now my contract has lost two days, and I have to strategize on how to recover the two days in order to complete my assignment on time (Lannon 57).
I propose that the company considers having a power generator that will automatically run when power is interrupted, and automatically shuts down when power is back.
Types of power supply
There are various types of power supply systems, but decidedly few can be considered for these tests. There is a power supply such as batteries and fuel cells but these cannot be considered due to their strengths.
For example, they are used to operate televisions and to start car engines (Basso 87). Electrical energy power transformation systems are other types of power supply, but they cannot be used as backup for these tests because, they convert available power.
Generators are power supply devices that use fuel to produce energy, and they can be considered for these tests. This is because, once power in interrupted, an automated generator can take charge producing power hence achieving the goal of having un-interrupted experiments. The last power supply system is the solar power systems.
These are devices used to tap energy from the sun hence producing power that can be used to run equipment in industries and domestic households. However, solar power may not be considered for this set up due to its disadvantages.
For example, since its power come from the sun there are chances of failure in cases where it happens to be raining for long. If power is interrupted when there is inadequate solar power stored, chances of holding the tests at a stall are high.
Strength of power supply required
Since power needed should be able to substitute the interrupted power from the mains, a strong power supply is required. This is because, power required to run the oven and freezers for long should be available and if a power supply cannot produce that equivalent of power the tests will be invalid.
Therefore, the power supply to be installed should be able to produce at least 30KvA. This is a generator that can supply both the testing equipment and other energy requirements in the company in case power is interrupted.
The generator to be considered for this company should be installed with sensors to detect the instance power goes off in order to switch on the generator, hence eliminating the power Gap.
It must also be designed in a way such that power overloading will be avoided; hence it should be able to go off when power resumes.
Power supplies required
One power generator can produce enough power to operate both the freezer and the oven. This can be achieved by installing a strong generator that can generate 30KvA.
This power is able to produce enough power for running both equipment and other electric appliances in the company (Lannon 97). This is because installing two generators to serve individual equipment may be expensive for the organization.

Therefore, it is advisable that the management consider installing one large power supply that will provide enough energy for all appliances in the company.
It is expensive to employ a full time technician since the generator will be automated. There is no need to have a technician since the generator will sense power interruptions and automatically start and automatically shut down when power resumes.
Leasing or buying the power supply
There is a need to weigh out options between leasing and purchasing power supply for the organization. In fact, purchasing the power supply is expensive since power interruptions are not common in the organization. Purchasing a generator will come along with other expenses such as the maintenance and installation expenses (Basso 77).
Leasing is more viable option because the power back up is vital during the short period of testing switches. Leasing power supply is cheap since the organization is not in charge of the maintenance expenses.
Installation costs will be remarkably little because the organization may set up a temporary structure for the machine since it is required for a short time.
Cost of purchasing versus cost of leasing
The cost of purchasing a new power generator and installation amounts to about $2500 which is extremely expensive considering that it is required for a short time. The cost of leasing a power generator with the same specifications for eight weeks will be $450.
The organization should consider installing a power supply back up system in order to avoid further loss in term of time and resources.
The manager should consider leasing a power generator that has the capacity to run both the freezer and the oven. This will help in saving cost of installing two generators to serve the oven and freezer individually.
