Hydran 201Ci Transformer Monitor

Hydran 201Ci Transformer Monitor

Product Details Introduction

GE Hydran 201Ci is a gas monitor designed specifically for transformers and oil immersed electrical equipment. It can continuously monitor the key dissolved gases in transformer oil, provide early fault warning, and thus improve the reliability and operational safety of equipment. The following is detailed information about the Hydran 201Ci transformer monitor:

main features 

Multi gas monitoring: Hydran 201Ci can monitor hydrogen (H ₂) and humidity (moisture content) in transformer oil. Hydrogen is an early indicator of transformer faults, such as overheating and arc discharge, while humidity levels can indicate the state of oil and solid insulation materials.

Continuous monitoring: Provides 24/7 continuous monitoring to ensure timely detection of issues in the early stages of failure.

Compact design: The equipment is compact and easy to install on existing transformers and other oil immersed electrical equipment.

Data communication: Supports multiple communication interfaces, such as 4-20mA and RS485 (Modbus RTU), facilitating remote data transmission and integration into existing monitoring systems.

Alarm function: Equipped with programmable alarm settings, users can set alarm thresholds based on the operating conditions of the device. When the monitoring value exceeds the set range, the device will sound an alarm.

advantage

Early fault warning: By continuously monitoring the hydrogen and humidity content, potential problems can be identified in a timely manner to prevent further deterioration of the fault.

Improve equipment reliability: Enhance equipment reliability and operational safety, and reduce unexpected shutdowns.

Reduce maintenance costs: Identify and address issues in advance, and reduce maintenance and repair costs.

Easy to integrate: Multiple communication interfaces support, making it easy to integrate into existing monitoring systems and achieve centralized management.

Installation and maintenance

The installation and maintenance process of Hydran 201Ci is simple, usually including the following steps:

Choose installation location: Determine the appropriate location for the transformer or equipment oil tank for installation.

Install sensor: Fix the sensor on the oil tank wall to ensure it can come into contact with transformer oil.

Connect power and communication lines: Follow the instructions to connect the power and communication lines to ensure the normal operation of the equipment and data transmission.

Calibration and testing: Perform calibration and functional testing according to the manufacturer's instructions to ensure accurate and reliable operation of the equipment.

conclusion

GE Hydran 201Ci is an efficient and reliable transformer monitor suitable for various oil immersed electrical equipment. By continuously monitoring key gas and humidity levels, it helps users identify potential issues in the early stages and take necessary preventive measures to ensure the safe operation of the equipment.
