Page 13: Storing And Transporting The Dga Monitor
Operation in cold environments may require trace heating elements and thermal insulation to be placed over the exposed sections of the oil pipes. If you have any questions, contact Vaisala for more information. Performing a site inspection in person is a good idea. Take photographs of the intended installation location, oil connections, and electrical connections. - Page 14 OPT100 Installation Guide M211857EN-A • There must be enough room and suitable supporting structures to install the DGA monitor in a vertical orientation. The DGA monitor must not be tilted more than 5 degrees. • If the Ground Mounting Set will be used to install the DGA monitor, there must be a level concrete surface that is at least 100 mm thick.

Page 15: Recommended Locations Of Oil Connections
Chapter 2 – Planning The Installation 2.8.2 Recommended Locations of Oil Connections You must build two oil lines between the DGA monitor and the transformer: one for intake of fresh oil, and an outlet line for returning the measured oil. Make sure you have appropriate adapters for connecting the oil lines to the valves. - Page 16 OPT100 Installation Guide M211857EN-A DGA monitor needs to pump oil in both directions during initialization and maintenance. To make sure this is possible, check that: • Intake and outlet valves are both below oil level in the transformer. There should be no risk of drawing gas into the pipes even when the flow is reversed.
