Preventive maintenance

Preventive maintenance means proper maintenance. It consists of process to grow before breakdown and prevent them before they occur. Basically the function of this section is Periodic visual inspection of various equipment to locate condition leading to break down. Repair defects at their initial stages. To attain major breakdown and repairs well planned preventive maintenance with half the… Read More »

Types of maintenance

Basically there are 3 types of maintenance- Corrective maintenance Preventive maintenance Contracted maintenance Corrective maintenance is done when an equipment fails or doesn’t work satisfactorily. Preventive maintenance is carried out to reduce the failure of equipment to minimum. In contracted maintenance contact terms are agreed by the supplier of the equipment and user. It may include both preventive… Read More »

Civil construction for installing of transformer

The following factors are taken into consideration at the time of installing transformers. Proper foundation- The foundation must be strong enough to bear the load of transformer without any vibration and must be made with proper floor label and plinth label. The label of concrete plinth should be above the maximum flood label. Suitable rail tracks should be… Read More »

Revolution of microprocessor

Revolution of microprocessor- Microprocessor is classified based on generation. In 1971 intel first, introduce 4bit microprocessor i.e. 4004. But this can’t be used publically. So next 4040 microprocessors is introducing by Intel. It is also a 4-bit microprocessor. In 1975 first 8bit microprocessor is introduced i.e. 8008. It based on PMOS technology. As it based on PMOS technology,… Read More »
