As a professional manufacturer with over a decade of experience in high-voltage electrical equipment, Jinhua Dika Electrical Equipment Co., Ltd. proudly presents our advanced Gas Insulated 33KV Metering Unit with an 11KV/110V output. Designed for precision and reliability in centralized power measurement systems, this unit is engineered to meet the rigorous demands of modern power distribution networks. Our commitment to quality, underscored by a robust ISO9001 quality management system, ensures that every metering unit delivers accurate data, enhanced safety, and long-term operational stability for utilities, industrial plants, and large commercial facilities worldwide.

This metering unit represents a significant leap in substation instrumentation, combining the superior insulation properties of SF6 gas with precision voltage transformation. It is a critical component for energy management, billing, and system protection.

Superior Gas Insulation (SF6): The core of this unit utilizes sulfur hexafluoride (SF6) gas as the insulating medium. This technology offers exceptional dielectric strength, effectively quenching arcs and providing reliable insulation in a compact design. It significantly reduces the risk of internal faults and enhances personnel safety compared to air-insulated units.
Precision Voltage Transformation (11KV/110V): The unit accurately steps down the primary 33KV system voltage to a standardized secondary output of 11KV/110V. This precise ratio is essential for connecting to revenue meters, protection relays, and energy management systems (EMS), ensuring billing accuracy and reliable system monitoring.
Robust Construction for Harsh Environments: Built with high-grade, corrosion-resistant materials, the enclosure typically achieves a minimum protection rating of IP54. This makes the unit suitable for both indoor switchgear and outdoor substation installations, resisting dust, moisture, and environmental contaminants.
Centralized Measurement & Data Integration: Specifically designed for centralized power measurement schemes, this unit facilitates the aggregation of consumption data from multiple points. It simplifies substation design, reduces cabling, and provides a consolidated interface for SCADA systems and smart grid applications.
Enhanced Safety Features: The sealed, gas-insulated design minimizes exposure to live parts. Integrated pressure gauges and density monitors provide real-time status of the SF6 gas, alerting operators to any potential leaks and ensuring operational integrity.
Flexible Configuration & Compatibility: We understand that projects have unique requirements. Therefore, our metering units offer customizable primary current ratings and optional communication protocols (like RS485 or Modbus) for seamless integration into existing digital control networks.

To provide a clearer overview, here are some typical technical specifications:

Parameter	Specification
Rated Primary Voltage	33 KV
Rated Secondary Voltage	11 KV / 110 V
Insulation Medium	SF6 Gas
Accuracy Class	0.2, 0.5, or 1.0 (as required)
Rated Frequency	50Hz / 60Hz
Short-Time Current Withstand	Customizable per IEC/ANSI standards
Enclosure Protection (IP)	IP54 (Higher ratings available)
Ambient Temperature Range	-25°C to +55°C

Benefits for Your Operation:

High Accuracy for Revenue Protection: Ensures precise measurement for accurate billing and reduces commercial losses.
Reduced Maintenance & Lifetime Cost: The sealed, gas-insulated design is virtually maintenance-free, lowering the total cost of ownership.
Space Optimization: The compact design saves valuable space in substations, allowing for more efficient layout planning.
Future-Proof Design: Ready for integration with smart grid technologies and advanced metering infrastructure (AMI).

Frequently Asked Questions (FAQ)

Q: What is the primary advantage of a gas-insulated design over an air-insulated one?
A: Gas insulation, typically using SF6, provides a much higher dielectric strength, allowing for a more compact and safer design. It offers better performance in polluted or humid environments and significantly reduces the risk of internal flashovers.
Q: Can this metering unit be used for both 50Hz and 60Hz power systems?
A: Yes, our units are designed to operate accurately on both standard power frequencies, 50Hz and 60Hz, making them suitable for international projects.
Q: What does the 11KV/110V output voltage ratio mean for my metering system?
A: This indicates the transformation ratio. The unit receives 33KV from the primary line and provides two standardized secondary outputs: 11KV and 110V. These outputs are directly compatible with a wide range of protection relays, energy meters, and monitoring devices.
Q: Is regular maintenance required for the SF6 gas?
A: The system is hermetically sealed for life under normal operating conditions. It is equipped with a pressure/density monitor to indicate gas level integrity. No regular maintenance of the gas is typically needed, contributing to low lifecycle costs.
Q: Are communication interfaces available for smart grid integration?
A: Absolutely. We offer optional digital communication interfaces such as RS485 with Modbus protocol. This enables seamless data transmission to SCADA, EMS, or other central monitoring systems.
Q: What certifications do your products hold?
A: Our manufacturing processes are certified under ISO9001 for quality management. The products are designed and tested in accordance with international standards like IEC and ANSI. Specific product certifications can be provided upon request based on the target market's requirements.
Q: What is the typical delivery lead time for a custom-configured unit?
A: Lead times vary based on order complexity and configuration. Generally, for standard specifications, delivery can be arranged within a few weeks. We provide accurate timelines upon receipt of your detailed specifications.
Q: Do you provide technical support during installation and commissioning?
A: Yes, we provide comprehensive documentation, including installation manuals and wiring diagrams. Remote technical support is available, and on-site assistance can be arranged if required.
