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?”

What is Leakage Current Testing and Measuring, How is it done?

Published by Carelabs (Carelabz) Leakage current is the current that streams from either DC or AC circuit in an equipment to the ground or framework and can be from the output or input. If the equipment is not properly grounded, the current flows through other paths such as the human body. This mighty also occur if the ground is incompetent or is disrupted unintentionally or intentionally.  The leakage current in anContinue reading “What is Leakage Current Testing and Measuring, How is it done?”

Power Quality Measurement and Analysis Basics

Published by Randy Barnett, Certified Energy Auditor and Trainer for NTT, Centennial, Colo. Email: randy@randybarnett.net , March 1st, 2012. How to interpret the results of a power quality site survey Analyzing electrical parameters associated with distributing electricity is viewed by many as complex engineering work. Yet, for engineers, electricians, and technicians troubleshooting equipment problems theseContinue reading “Power Quality Measurement and Analysis Basics”
