When a sensitive circuit must under no circumstances have too high a supply voltage applied, then some means of disconnecting the supply must be provided. One way to achieve this is to trigger a ...
A Zener diode can be used as an overvoltage protector that shunts fault current through ground via a current-limiting resistor (Figure 2). Note that the Zener protection is effective only if the Zener ...
The National Electrical Code (NEC) requirements for overvoltage protection can be found in Art. 242. This Article is new with the 2020 NEC, and it replaces Art. 280 and Art. 285. Those Articles ...
When testing your devices, it may become apparent that the device needs protection against an overvoltage condition. Most power supplies offer some form of overvoltage-protect (OVP) circuit. The OVP ...
With the 2020 revision of the NEC, Art. 242 replaced two individual Articles that appeared in earlier editions of the Code — Art. 280 [Surge Arrestors] and Art. 285 [Transient Voltage Surge ...
Capacitor Voltage Transformers (CVTs) are central to modern power systems, where they not only scale high transmission voltages into measurable signals but also ensure the precision needed for ...
High demands on the robustness of electronic systems, especially in industrial environments, continually present developers with great challenges. Overvoltage protection is one key design ...
Voltage transformers (VT) are used in electrical grids for metering and/or protection purposes. The high requirements regarding their precision demand a calibration ...
The NCP346 from ON Semiconductor is an overvoltage protection circuit (OVP) optimized for applications with an external ac-dc adapter, a car charger accessory and/or a battery recharger. Delivering ...
