válvula de aceite del transformador. No

requiere de tubería ni bombeo. Entradas para

otros sensores.

• El sensor de gas responde 100% ante el

Hidrógeno (gas de falla general) y es también

sensible al Monóxido de Carbono

(sobrecalentamiento del papel), Acetileno

aceite) cubriendo así las principales causas de

fallas.

• El sensor de humedad mide agua en aceite,

resultado de la degradación del papel aislante

(produce CO + agua)

analizar datos, como lo hace con cualquier otro equipo de monitoreo AGD de GE

Descripción del producto

Los transformadores son un componente clave y costoso en la red eléctrica y tener conocimiento

sobre su condición de salud es algo esencial para tener una red confiable. Cuando el aislamiento de

un transformador es sometido a gran estrés, se producen gases que se disuelven en el aceite. El

Análisis de Gases Disueltos en aceite (AGD) es reconocido como el mejor indicador de una falla en

desarrollo.

El Hydran M2 es un equipo en línea que monitorea gases disueltos y humedad en el aceite que alerta

al personal sobre un desarrollo de falla en el transformador. Provee información clave sobre el

monitoreo y minimiza el riesgo de salidas de servicio no planificadas.

Conectando sensores adicionales (Ej: temperatura superior e inferior del tanque aceite, carga del

transformador o temperatura ambiente), se puede capturar información adicional para luego

correlacionarla con los valores del AGD y la humedad, obteniendo un análisis más profundo de la

condición del transformador.

Estos valiosos datos no pueden ser únicamente transmitidos usando la amplia gama de

comunicaciones disponibles para el M2. sino que pueden ser convertidos en información útil mediante

el cálculo de Modelos Matemáticos basado en el estándar  IEEE®  con la finalidad de proveer mayor

información sobre la condición del equipo.

other parameters such as top oil temperature, load current and through the use of IEEE based

mathematical models, can provide further insight on changing transformer conditions

• Providing critical transformer gas behavior data for Asset Performance Management (APM)

strategies, facilitating planning of site intervention and maintenance activities

• Supports a wide range of communication methods and protocols to enable easy and secure

integration with GE’s digital platforms including Perception™ transformer fleet management

software, DS Agile substation HMI, PREDIX™, and other APM software tools, historians and SCADA

systems

Applications

Advanced, flexible and expandable DGA monitoring solution tailored for utility and industrial

transformers.

Easily integrates with Kelman multi-gas DGA devices and the Multilin 845 protection & control

relay to provide continuous synchronization of chemical and electrical measurements for enhanced

transformer monitoring

Enhanced Monitoring with Extended Sensor Life

When a transformer’s insulation system is overstressed, the oil and paper undergo chemical

degradation producing both hydro-carbon gases and moisture that dissolve into the insulating oil. This

increased ageing will shorten the transformer’s life, impact its reliability and in some cases can even

lead to catastrophic failures.

The Hydran M2-X is the next generation of the field-proven family of Hydran DGA monitoring solutions.

It provides continuous monitoring of gas and moisture levels to alert users of developing faults and

minimize the risk of unplanned outages. The M2-X builds on GE’s strong domain expertise to deliver an

optimized, low maintenance monitoring device with an extended sensor life.

Conclusion

CT/VT modules with enhanced diagnostics, released on 23 October 2006 with firmware 5.2.

offer much higher security for internal CT/VT module error detection and prevent undesired operations of URs.

Every UR firmware released since version 5.2 supports CT/VT modules with enhanced diagnostics,

which greatly improves the security and reliability of the protection system.

To take advantage of this feature, a relay hardware and possibly firmware upgrade is required.

If the existing relay has a firmware version below 4.0. GE recommends purchasing a

UR Upgrade Kit that allows modernization of the obsolete relay hardware

while taking advantage of the relay modularity.

The UR Upgrade Kit contains a new CPU and CT/VT modules that can be

inserted in an existing relay case (case is fully backwards compatible).

If the relay currently has firmware version 4.0 to 5.0. the latest firmware

can be downloaded from the GE Multilin website, and Enhanced Diagnostic

CT/VT modules (8L, 8M, 8N, 8R, 8S, 8V) can be purchased from the GE Online Store.

Consult with your local GE representative if you have any questions on the upgrade process.
