As a leading manufacturer in electrical measurement technology, Jinhua Dika Electrical Equipment Co., Ltd. is proud to present our high-precision Open Core Current Transformer. Designed for the 100A to 600A range, this single-phase transformer is engineered for reliability and ease of installation in diverse industrial and commercial settings. Our commitment to quality, backed by a robust manufacturing process and a global export footprint, ensures you receive a product that delivers accurate current sensing without system downtime.

This epoxy resin encapsulated current transformer is a cornerstone for efficient energy management. Its innovative open-core design allows for quick and safe installation around existing conductors, eliminating the need to disconnect power. This feature is invaluable for retrofit projects and ongoing system monitoring where operational continuity is critical.

Core Product Features & Technical Advantages:

Non-Intrusive Installation: The split-core design allows the transformer to be easily clamped around a live conductor, making it ideal for adding metering or monitoring to existing electrical systems without costly shutdowns.
Robust Epoxy Resin Encapsulation: The housing provides excellent protection against moisture, dust, chemicals, and mechanical stress, ensuring long-term stability and performance in harsh environments.
Wide Current Range: Available from 100A to 600A, offering flexibility for a variety of applications from commercial building monitoring to industrial machinery.
High Accuracy & Linearity: Manufactured with precision-wound coils and high-grade magnetic cores to ensure reliable and consistent output signals across the specified current range.
Safe and Reliable Operation: Provides galvanic isolation between the high-current primary circuit and the low-voltage secondary measurement circuit, enhancing system safety.
Versatile Output Options: Can be configured to provide standard output signals such as 0-5V, 0-10V, or 4-20mA, making it compatible with a wide array of energy meters, PLCs, SCADA systems, and data loggers.

Frequently Asked Questions (FAQ):

Q: What is the main advantage of an open-core design over a solid-core transformer?
A: The primary advantage is the ability to install it without breaking the conductor. You simply open the core, clamp it around the wire, and close it. This allows for safe installation on energized lines and is perfect for retrofitting metering into existing systems.
Q: Can this transformer be used for both 50Hz and 60Hz power systems?
A: Yes, this current transformer is typically designed to operate accurately at both standard power frequencies, 50Hz and 60Hz. Please confirm the specific model's frequency range when ordering.
Q: What output signals do you offer?
A: We offer versatile output options to suit different monitoring equipment. Common outputs include analog signals like 0-5V DC, 0-10V DC, or 4-20mA, as well as standard current outputs (5A/1A). The specific output can be customized based on your application requirements.
Q: Is the epoxy resin encapsulation important?
A: Absolutely. The epoxy resin provides a sealed, rigid housing that protects the internal windings and core from environmental factors like humidity, dust, and mild chemical exposure. It also provides excellent electrical insulation and mechanical strength.
Q: How do I select the correct current rating (e.g., 100A vs. 600A)?
A: Select a rating that is equal to or higher than the maximum continuous current you expect to measure on the conductor. For optimal accuracy, it is recommended to choose a rating where your normal operating current is between 20% and 100% of the transformer's rated value.
Q: Are these transformers suitable for outdoor use?
A: The epoxy resin encapsulation provides good protection, making it suitable for many outdoor or harsh indoor environments. For specific outdoor ratings or extreme conditions, please inquire about the IP (Ingress Protection) rating of the model you are considering.
Q: Do you provide calibration certificates?
A: Calibration certificates are available as an optional service upon request. This provides documented traceability of the transformer's accuracy at the time of shipment.
Q: What is the typical lead time for orders?
A: Lead times vary based on order quantity, customization, and current production schedule. Standard models often have shorter lead times. Please contact us with your specific requirements for an accurate delivery estimate.
