GE Hydran M2 Online Variable Voltage Gas Detection Equipment

Description

GE Hydran M2 Product Description:
GE Hydran M2 is an online transformer detection gas equipment designed specifically for the electrical equipment industry. It adopts a continuous cycle working mode to ensure the stable operation of transformers.

Hydran M2

Main features and advantages:
Gas and humidity monitoring
It can continuously monitor the comprehensive value of multiple fault gases (in ppm), or only monitor the hydrogen value (depending on the type of sensor purchased). For example, the ability to accurately detect the generation and accumulation of gases such as hydrogen, acetylene, methane, ethane, and ethylene, whose abnormalities are often important signs of insulation material failure. At the same time, it can also track the moisture content in oil in real time (measured in% RH and ppm). For oil immersed transformers, humidity monitoring is crucial for evaluating insulation performance and preventing problems caused by humidity.
When using a composite gas sensor, its response rate to hydrogen gas reaches 100%, and it is also sensitive to carbon dioxide (produced by overheated paper insulation); If a hydrogen sensor is selected, it will show a 100% response to hydrogen gas.
Multivariate data processing and model computation: After adding additional sensors, Hydran M2 can be processed according to IEEE standards ® And IEC ® Constructing a standard mathematical model for transformers provides richer information for a deeper understanding of transformer performance. For example, by connecting sensors such as top and bottom oil tank oil temperature, transformer load, or ambient temperature, more information can be collected and correlated with fault gas and humidity values for in-depth analysis. At the same time, it can transmit raw data through various communication methods and convert the data into a transformer mathematical model based on IEEE standards through onboard computing, outputting useful information such as estimated winding hotspot temperature, moisture content in paper, moisture foaming temperature, insulation aging degree, overload capacity, cooling efficiency, on load tap changer (OLTC), etc., to help operation and maintenance personnel comprehensively grasp the health status of transformers.
Convenient installation and reliable operation: The device has a compact structure and can be permanently installed on a single transformer oil valve without the need for additional pipelines or pumps, making installation simple. There are no moving parts inside, reducing the possibility of malfunctions. Equipped with a vacuum resistant gas extraction membrane and a built-in temperature regulation system, it can adapt to complex working environments and ensure stable operation of the equipment. Automatic comprehensive self inspection is conducted every 15 days. If a fault is detected (including power failure, oil valve closure, sensor failure, etc.), a service alarm will be immediately triggered. At the same time, it has a complete self diagnostic function, which can detect sensor faults or system problems in a timely manner and issue corresponding alarms.
Wide communication and flexible configuration: Supports multiple communication methods and protocols, making it easy to integrate into SCADA or DCS systems. The standard configuration is RS485 output, and TCP/IP copper cable or fiber optic output can also be optionally selected. Up to 4 input or output cards can be selected for easy connection to other devices or function expansion. It can flexibly set local and remote alarms according to needs, with two alarm levels (one for early warning and one for alarm). When a fault gas or abnormal humidity level is detected, an alarm will be issued in a timely manner to remind operators to take corresponding measures and reduce the risk of equipment damage or accidents. In addition, alarms can be set based on optional analog input cards or calculated transformer models.
Data recording and storage: With data recording and storage functions, it can record data and important events for up to one year, facilitating subsequent analysis of equipment health status and performance history, and providing strong data support for equipment maintenance and management.

Application areas:
Transformer monitoring: It can monitor the operating status of transformers in real time, detect potential problems in a timely manner, such as abnormal temperature rise, humidity changes, sediment accumulation, and gas anomalies, and help operation and maintenance personnel take measures in advance to avoid the expansion of faults.
Fault diagnosis: By continuously monitoring key parameters of the transformer, Hydran M2 can assist in fault diagnosis. Once a problem that may cause equipment failure is detected, an alarm will be immediately issued, providing a basis for rapid location and resolution of the fault.
Gas analysis in oil: With precise monitoring of gas content in oil, this equipment can reveal the internal state of transformers, such as gases generated by partial discharge, arc, and other faults, thereby gaining a deeper understanding of the operating conditions inside transformers.
Temperature monitoring: It can not only monitor the internal temperature of the transformer, but also the external environmental temperature, help evaluate the thermal stability of the equipment, identify abnormal temperature rise in advance, and ensure that the transformer operates within the appropriate temperature range.
Remote monitoring: With the help of network connectivity, Hydran M2 enables remote monitoring, allowing operation and maintenance personnel to access key status information of transformers at any time, regardless of their location, greatly improving operation and maintenance efficiency and timeliness.
