  • Page 14: Installation Location Of Dga Monitor

    OPT100 Installation Guide M211857EN-F 2.8.1 Installation Location of DGA monitor The DGA monitor can be attached to the transformer chassis or to its immediate vicinity. The location must fulfill the following requirements: • The location must be close to the oil connections to minimize the length of the oil lines. The maximum length of the lines is 10 m (33 ft) each.

  • 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 a return line for the measured oil. Make sure you have appropriate adapters for connecting the oil lines to the valves.

  • Page 16: Regulatory Compliances

    OPT100 Installation Guide M211857EN-F DGA monitor needs to pump oil in both directions during initialization and maintenance. To make sure this is possible, check that: • Intake and return valves are both below oil level in the transformer. There should be no risk of drawing gas into the oil lines even when the flow is reversed.
