Qualitrol DGA 150 /250 / 400 Dissolved Gas Analyzers

QUALITROL DGA 150/250/400 DISSOLVED GAS ANALYZERS

IRetrofits easily into existing transformers

Hydrogen is generated under most fault conditions that occur in power transformers and is an early indication of larger problems in the transformers lifecycle. Real time monitoring of hydrogen provides an economical method for maintaining the overall health of the transformer.

Features

Enables real-time monitoring of hydrogen (H₂), an early indicator of transformer fault conditions
Accurately measures hydrogen without interference from other fault gases
Integrates with existing monitoring equipment and utilizes available transformer installation points
Integrated oil sampling valve with Luer fitting for easy sample collection

Option

Mounting options:

DGA 150 - Drain Valve - 1.5" NPT Union fitting (thread mount)
DGA 250 - RPRR - 2.5" NPT Union fitting (thread mount)
DGA 400 - RPRR (flange mount)

A variety of service plans to ensure proper monitor operation over the long term

Application

Qualitrol's DGA series enables online monitoring of dissolved hydrogen in a variety of transformers including conservator, air and nitrogen blanketed models. Sensors can be easily mounted directly in the insulating oil or in the gas headspace, providing multiple mounting options. Additionally, Qualitrol has integrated hydrogen sensing capabilities in its latest Rapid Pressure Rise Relief (RPRR) design (optional).
