Can Protection CT be used as Metering CT & Vice Versa?
Web17 dec. 2024 · Metering equipment connected to a protection CT must be capable of withstanding the current that flows during a fault on the primary circuit. For example, if … WebThe thicker the wire the lesser will be the resistance, and as a result of larger cross sectional area of the conductor, the VA burden of the connecting wire will be less.The measuring instrument or the protection relay must be installed as near to the current transformer as possible so that the lead resistance can be minimized. WebThe current transformer and potential transformer (also called voltage transformer) are both measuring devices. A CT lowers the current signals for measurement purposes, while a PT lowers high voltage values into lower ones. The transformers are designed to measure whether power systems are both accurate and safe. grais leather
