Fs Electrical is equipped with only the best and we only use high quality spares and parts to ensure the best end results
We completely strip the unit and all of its components to give the best quality end product.
A large current ( between 0A and 2000a depending on system specification and test requirements) is injected directly on the primary side of the electrical system, such as a current transformer. Primary injection testing is suitable for testing a complete protection circuit from current transformers al the way to protection relays Ratio tests are performed by applying a suitable voltage (below saturation) to the secondary of the CT under test while the primary side voltage is measured to calculate the turns ratio from the expression above. Insulation resistance readings should remain fairly constant over a period of time.
Megger test / Sheath resistance test procedure for cables. A Megger test or sheath resistance test is used to diagnose cable faults, either short circuit problem, water penetration, moisture or current leakage. A Megohmmeter is used to measure the resistance of the crossed-link to an applied DC Working Principle of Megger. Voltage for testing produced by hand operated megger by rotation of crank in case of hand operated type, a battery is used for electronic tester. 1000 V to 5000 V is used for testing for high voltage electrical systems. Megger is a measuring instrument used for the measurement of insulation resistance of an electrical system. An electrical system degrades its quality of insulation resistance with time and various environmental conditions including temperature, moisture, dust particles & humidity.
