1. What is Electrical Standards


An electrical reference standard is a calibrated and standardized device or system used in electrical metrology to provide accurate and traceable measurements of electrical parameters such as voltage, current, resistance, power, and energy. These standards serve as reference points against which other instruments or measurements can be compared to ensure accuracy and consistency. Electrical reference standards are typically highly precise instruments that adhere to internationally recognized standards and are used in various industries including electronics, telecommunications, power generation, and testing laboratories. They play a crucial role in maintaining the reliability and accuracy of electrical measurements and ensuring compliance with regulatory requirements.


2. TUNKIA Reference Standards Products


To verify the performance of an electrical calibrator or dc calibrator, an electrical standard is needed. TUNKIA reference standards include standards of voltage, current and resistance; standard meters of current, voltage, resistance, power and energy; standard sources of current, voltage, resistance, power and energy.
