Should you ground a DC power supply?
A:Yes, in many cases, it is necessary to ground a DC power supply. Grounding helps to improve safety by preventing electric shock in case of insulation failure. It also helps to reduce electromagnetic interference and stabilize the electrical potential of the power supply, which is beneficial for the proper operation of electronic devices. However, there are some specific low - voltage and isolated DC power supplies that may not require grounding depending on the application and safety regulations.

How Altitude Affects HV Equipment Insulation & Temperature Rise？As altitude increases, air density, temperature, and atmospheric pressure decrease accordingly, leading to reduced dielectric strength of air gaps and external insulation performance of porcelain components. This results in degraded external insulation performance for high-voltage electrical equipment. Since most high-voltage equipment is designed for installation at altitudes below 1,000 meters, using such equipment at elevations exceeding 1,000 meters may compromise reliable insulation performJames10/23/2025 -
What Causes CT20 Mechanism to Fail to Close? Insufficient Closing Solenoid Stroke Is KeyThe CT20 series operating mechanism is a classic design. One common cause of failure to close is an improperly adjusted, overly short stroke of the closing solenoid. The rated stroke is approximately 5mm. However, due to vibration or incorrect adjustment after maintenance, the stroke may decrease to around 3mm, potentially causing the mechanism to fail to operate. If the control system continuously issues a closing command under such conditions, the solenoid remains energized, which can lead toFelix Spark10/23/2025 -

Practical reactors are constructed by winding the conductor into a solenoid shape, known as an air-core reactor. To further increase inductance, a ferromagnetJames10/23/2025 -
35kV Distribution Line Single-Phase Ground Fault HandlingDistribution Lines: A Key Component of Power SystemsDistribution lines are a major component of power systems. On the same voltage-level busbar, multiple distribution lines (for input or output) are connected, each with numerous branches arranged radially and linked to distribution transformers. After being stepped down to low voltage by these transformers, electricity is supplied to a wide range of end users. In such distribution networks, faults such as phase-to-phase short circuits, overcurreEncyclopedia10/23/2025
