i-Con SF6 Gas Density Monitoring System

Legislation

As a result of recent European legislation on the control of greenhouse gasses, utilities and manufacturers alike are now being forced to reduce SF6 emissions to minimal levels, namely, 0.5% per annum.

In order to achieve this, and also to prove to the regulatory bodies that this is being achieved, a more accurate inventory system for the SF6 gas in use on substations is required.

Solution

The i-ConGDM – SF6 Gas Density Monitoring System has been designed to allow the user a greater degree of flexibility for measurements and alarms than that currently provided by gauges with contacts.

The system uses SF6 density transducers which operate with a 4 to 20mA current loop technology for high noise immunity. The result is a full SF6 inventory management system capable of providing advance warning of SF6 leaks with an accuracy of 0.5% per annum.

Transducers can be mounted directly to the GIS chamber via an industry standard gas “top-up” connection or retrofitted to gas monitoring boxes housing SF6 gas pressure gauges where ease of access is a requirement.

Transducers are connected to an i-Con Node Unit installed within the GIS Hall. Up to 45 Density transducers can be connected to each Node Unit which houses the data acquisition and storage facilities.
