Frequently Asked Questions (FAQ)
What is a current transformer (CT)?
A current transformer (CT) is a device designed to transfer and measure electrical current based on the principle of electromagnetic induction.
What components make up a dry-type CT?
This dry-type CT is composed of a primary winding, outer sheath, capacitive main insulation structure, silicone rubber umbrella skirt pressure balancing cover at both ends, shell, secondary winding, and a conductive wire clip.
What are the main advantages of dry-type current transformers?
They offer significant benefits including no oil-filling, no gas-filling, no porcelain construction, small volume, light weight, minimal maintenance workload, and reliable fire and explosion protection.
How does silicone rubber insulation improve performance?
By using silicone rubber material as the outer insulation, the CT achieves equal surface voltage distribution, which further improves the overall pollution flashover voltage resistance.
What does the LGB model designation stand for?
"LGB" designates a dry-type current transformer equipped with a protection coil. The accompanying number represents the rated voltage in kV (for example, LGB-110 stands for 110 kV, and LGB-220 stands for 220 kV).
HEADING-TYPE-1
High voltage parallel capacitors are suitable for parallel connection in AC power systems with power frequency (50Hz or 60Hz) of 1kV and above. They are used to compensate for inductive reactive power, improve power factor, improve voltage quality, reduce line losses, and fully utilize the efficiency of power generation and supply equipment.
