On-Line Testing for Surge Arresters Below 110kV: Safe and EfficientAn On-Line Testing Method for Surge Arresters at 110kV and BelowIn power systems, surge arresters are critical components that protect equipment from lightning overvoltage. For installations at 110kV and below—such as 35kV or 10kV substations—an on-line testing method effectively avoids the economic losses associated with power outages. The core of this method lies in using online monitoring technology to evaluate arrester performance without interrupting system operation.The test principle is bOliver Watts10/23/2025 -
Why Upgrade to Maintenance-Free Transformer Breathers?Maintenance-Free Moisture Absorption Technology for Oil-Immersed TransformersIn traditional oil-filled transformers, the temperature control system causes thermal expansion and contraction of insulating oil, requiring the sealing gel chamber to absorb significant moisture from the air above the oil surface. The frequency of manual silica gel replacement during patrols directly impacts equipment safety—delayed replacement can easily lead to oil degradation.

What Is an MVDC Transformer? Key Applications & Benefits ExplainedMedium-voltage DC (MVDC) transformers have a wide range of applications in modern industry and power systems. The following are some key application areas for MVDC transformers: Power Systems: MVDC transformers are commonly used in high-voltage direct current (HVDC) transmission systems to convert high-voltage AC into medium-voltage DC, enabling efficient long-distance power transmission. They also contribute to grid stability control and power quality improvement. Industrial Applications: In inEdwiin10/23/2025 -
What Is MVDC Technology? Benefits, Challenges & Future TrendsMedium-voltage direct current (MVDC) technology is a key innovation in power transmission, designed to overcome limitations of traditional AC systems in specific applications. By transmitting electrical energy via DC at voltages typically ranging from 1.5 kV to 50 kV, it combines the long-distance transmission advantages of high-voltage DC with the flexibility of low-voltage DC distribution. Against the backdrop of large-scale renewable integration and new power system development, MVDC is emergEcho10/23/2025 -
Why Does MVDC Grounding Cause System Faults?Analysis and Handling of DC System Grounding Faults in SubstationsWhen a DC system grounding fault occurs, it can be classified as single-point grounding, multi-point grounding, loop grounding, or reduced insulation. Single-point grounding is further divided into positive-pole and negative-pole grounding. Positive-pole grounding may cause misoperation of protection and automatic devices, while negative-pole grounding may lead to failure to operate (e.g., relay protection or tripping devices).

Why Can't VT Be Shorted & CT Be Opened? ExplainedWe all know that a voltage transformer (VT) must never operate short-circuited, while a current transformer (CT) must never operate open-circuited. Short-circuiting a VT or opening the circuit of a CT will damage the transformer or create hazardous conditions.From a theoretical standpoint, both VTs and CTs are transformers; the difference lies in the parameters they are designed to measure. So why, despite being fundamentally the same type of device, is one prohibited from short-circuit operatioEcho10/22/2025
