96T, 96L, 96C, 72T, 72L, and 72C Mounted Analog Indicating AC, DC Current and Voltage Measuring Instrument User Manual Standard: GB/T 7676 Please carefully read this User Manual before installing and operating the product, and keep this manual properly for future reference 1 Scope of Application The AC ammeter and voltmeter in this series of products are used in the 50Hz AC circuit for the measurement of the current and voltage, and the DC ammeter and voltmeter are used in the DC circuit for the measurement of the current and voltage. In addition to separate use, this product is primarily used as a matching instrument panel for the power systems such as transmission and distribution stations and power grids and for various electrical installations such as switchgear cabinets, power supply cabinets, control cabinets, and compensation cabinets. 2. Structure Features In this series of products, the AC ammeter is an electromagnetic mechanism, the AC voltmeter has toe mechanisms: electromagnetic system and rectifier system, and the DC ammeter and voltmeter are magnetoelectric mechanisms. The dials adopt the plug-in structure, and all of them are printed dials. 3 Working Principle Electromagnetic system: The measured current or voltage signal acts on the fixed coil; when the current flows through the coil, the fixed iron core and the moving iron core inside will be magnetized in the same polarity, and the action torque is generated between the moving and fixed iron cores to drive the pointer to deflect. When the reaction moment of the balance
