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 -
Why Are Voltage Transformers Burning Out? Find the Real CausesIn power circuits, voltage transformers (VTs) are often damaged or burned out. If the root cause is not identified and only the transformer is replaced, the new unit may quickly fail again, disrupting power supply to users. Therefore, the following checks should be performed to determine the cause of VT failure: If the voltage transformer has ruptured and oil residue is found on the silicon steel laminations, the damage was likely caused by ferroresonance. This occurs when unbalanced voltages orFelix Spark10/22/2025 -
Things to Know When Operating Voltage Transformers: De-energizing and Energizing ProceduresQ:What are the Operating Sequence Rules for the Secondary Miniature Circuit Breaker and High-Voltage Power Supply During Voltage Transformer De-energizing and Energizing?A:For busbar voltage transformers, the principle for operating the secondary miniature circuit breaker during de-energizing and energizing is as follows: De-energizing:First, open the secondary miniature circuit breaker, then disconnect the high-voltage power supply of the voltage transformer (VT).
