What is Earth Grounding?

Published by Carelabs (Carelabz) IEEE defines earth as a conducting connection, whether intentional or accidental, by which an electric circuit or equipment is connected to the Earth, or to some conducting body of relatively large extent that serves in place of the earth. The connection(s) to Earth are done by an assortment of metallic means intended to beContinue reading “What is Earth Grounding?”

What & Why of PFC and PSC Test?

Published by Carelabs (Carelabz) Prospective Short Circuit (PSC) and Prospective Fault Current (PFC) are both designed to calculate the maximum current that will flow within a fault loop path during the event of an electrical fault as required by regulations.  The Prospective Short Circuit Current is the maximum current that could flow between Line and Neutral conductors on a single phase supply or between Line conductorsContinue reading “What & Why of PFC and PSC Test?”

What is Ground Fault Testing, Why is it Important?

Published by Carelabs (Carelabz) A ground fault is any short circuit that outcomes in an unintentional connection amid a ground and energized ungrounded phase conductor and ground. Ground faults are the most common type of fault on power distribution systems. They are due to the insulation failure or accidental grounding of an ungrounded phase conductorContinue reading “What is Ground Fault Testing, Why is it Important?”

Learn What is Earth Ground Test, Why and How is it done?

Published by Carelabs (Carelabz) Electrical safety testing is essential to ensure safe operating standards for any product that uses electricity. Various governments and agencies have developed stringent requirements for electrical products that are sold world-wide. Several tests are conducted to check the safety of products. One among that is earth test. Potentially the most dangerousContinue reading “Learn What is Earth Ground Test, Why and How is it done?”
