There are two types of current: direct current (DC) and alternating current (AC).

• Direct current (DC) flows in one direction only, typically produced by batteries or power supplies.

• Alternating current (AC) periodically changes direction, commonly used in household electrical systems.

• DC is used in electronic devices like computers and cell phones, while AC powers appliances and lighting.

• Examples of DC include car batteri...read more

Voltage value L-L is the voltage between two phases, while L-N is the voltage between a phase and neutral.

• Voltage value L-L is also known as line-to-line voltage.

• Voltage value L-N is also known as line-to-neutral voltage.

• L-L voltage is typically higher than L-N voltage in a three-phase system.

• For example, in a 120/208V three-phase system, the L-L voltage is 208V, while the L-N voltage is 120V.

A step-up transformer increases voltage while a step-down transformer decreases voltage.

• Step-up transformer increases voltage from primary to secondary winding

• Step-down transformer decreases voltage from primary to secondary winding

• Step-up transformers are used in power transmission to increase voltage for long-distance transmission

• Step-down transformers are used in power distribution to decrease voltage for consumer u...read more

The number of Engineering Documents processed in an EPC project varies depending on the size and complexity of the project.

• The number of Engineering Documents processed in an EPC project can range from hundreds to thousands.

• These documents include drawings, specifications, calculations, reports, and other technical documents.

• The exact number of documents will depend on the scope of the project, the number of discipline...read more
