Frequently Asked Questions (FAQ):

What is the main advantage of an "Open Type" current transformer?
The open-type (or split-core) design allows the transformer to be installed around an existing conductor without cutting or disconnecting the line. This significantly simplifies installation, reduces downtime, and is ideal for retrofitting or monitoring live circuits.
How does the 0.5S accuracy class benefit my application?
Accuracy class 0.5S indicates very high precision, especially at low currents (from 1% to 120% of rated current). It is primarily used for revenue metering (billing) and high-performance protective relaying where measurement error must be minimal.
Is this transformer suitable for both indoor and outdoor installation?
Yes, with its robust insulation and wide operating temperature range (-40°C to +70°C), the LMZK-10 is designed to perform reliably in both indoor electrical rooms and outdoor substation environments.
Can I request a specific primary current rating?
Absolutely. As a manufacturer, we offer customization. Common ratings like 100A, 200A, or 400A are available, and other values can be produced upon request to match your system's needs.
What is the typical secondary current output?
The standard secondary current is usually 5A or 1A, aligning with common meter and relay input standards. The specific output can be confirmed based on your order requirements.
Does it comply with international standards?
The transformer is designed in accordance with prevalent international standards for current transformers, such as IEC 61869 series. Specific compliance details can be provided upon request.
What mounting method is required?
The transformer is supplied with a mounting bracket or suitable fixtures. It can be securely mounted on a panel, wall, or support structure near the conductor being measured.
How does your company ensure product quality?
We adhere to structured manufacturing and quality control processes. Our operational approach focuses on consistency and reliability, supported by a team dedicated to producing electrical equipment that meets performance expectations.
