The “Five Protections” of high-voltage switch...
The “Five Protections” of high-voltage switchgear are designed to ensure personal and equipment safety. Specifically, they include: preventing accidental opening and closing of circuit breakers; preventing opening and closing of disconnectors under load; preventing the connection (or ...Read More -
The energy efficiency level of the transformer
Transformer efficiency refers to the efficiency with which the transformer converts electrical energy into another voltage during operation. It represents the ratio between the energy consumed by the transformer during the energy conversion process and the energy output. High efficiency means low...Read More -
The core parameters of the transformer are no-load loss a...
Transformer losses are primarily categorized as no-load losses and loaded losses. No-load losses, also called iron losses, are primarily caused by hysteresis and eddy current losses in the core. They are voltage- and frequency-dependent, but independent of the load current. Load losses, also call...Read More -
Main technical parameters of transformer
Under specified operating conditions and operating conditions, the transformer’s key technical data is generally indicated on the nameplate. These primarily include: rated capacity, rated voltage and its tapping, rated frequency, winding connection group, rated performance data (impedance v...Read More -
Application of capacitor compensation in power system
Capacitor compensation is primarily used in power systems to improve power factor, improve voltage quality, reduce line losses, and enhance power supply system efficiency and stability. By properly deploying capacitors in a power system, they can compensate for the reactive power generated by ind...Read More -
Do you recognize the primary system diagram of the KYN28-...
A complete high-voltage system consists of the following components: 1. Incoming switchgear (receives power from the high-voltage system, i.e., the source of the high-voltage system) 2. PT switchgear (provides busbar voltage signals for this section of the high-voltage system, enabling ene...Read More -

A wide variety of distribution cabinets
Distribution panels can be categorized in various ways based on different standards, primarily by voltage level, structural features, installation method, and location. 1. By Voltage Level: • Low-voltage distribution panels: Typically refers to distribution panels rated at 1 kV or below, used to ...Read More -
Do you know short circuit impedance?
Short-circuit impedance is a critical parameter of electrical equipment such as power transformers and reactors. It characterizes the impedance characteristics of the equipment under short-circuit conditions and is crucial for equipment operation, protection design, and grid stability analysis. C...Read More -
Do you know the power supply radius of the transformer?
The power supply radius of a transformer refers to the distance from the transformer to the farthest power-consuming device. It is affected by several factors, including voltage level, cable type, load size, and voltage quality requirements. Generally speaking, the low-voltage power supply radius...Read More -
Compensation application of low voltage active filter cab...
Active power filters are primarily used to dynamically filter harmonics and compensate for reactive power, improving power quality and equipment reliability. They detect and compensate for harmonic currents in real time, making the current injected into the grid closer to a sine wave, thereby red...Read More
