Utility load shifting to DG manually involves following a standard operating procedure (SOP) to ensure smooth transition.

• Ensure DG is in good working condition before shifting load

• Isolate utility power source before transferring load to DG

• Monitor DG performance during load shifting process

• Gradually shift load to DG to prevent overload

• Regularly check and maintain DG for optimal performance

Temperature refers to the degree of hotness or coldness of a body or environment, while humidity is the amount of water vapor present in the air.

• Temperature is measured in degrees Celsius or Fahrenheit, while humidity is measured in percentage.

• Temperature affects how hot or cold we feel, while humidity affects how sticky or dry the air feels.

• High temperature with high humidity can make it feel hotter than it actually i...read more
