2.2 Installation phases

Perform the installation of the DGA monitor in the following phases:

• Planning

• Mechanical installation

• Electrical installation

• Commissioning

• Installation reporting

These phases correspond to chapters of the Installation Guide. Post-installation checklist is included as part of the installation report template. See Post-installation checklist (page 78).

2.3

Required personnel

Installation of the DGA monitor requires two persons. While most of the installation and commissioning tasks can be done by a single person, safe carrying and lifting of the DGA monitor requires two persons.

Installers must have the necessary training to legally perform all required tasks. For example, connecting the DGA monitor to mains power must be done by a licensed electrician.

Chapter 2 – Planning the installation

Applicable legislation and site safety guidelines may require additional personnel to be present in the installation.

After installation, store the packaging in a dry place. You can reuse it for storage and transport later.

2.7

Reinstalling DGA monitor

If you want to relocate an already installed DGA monitor, you must prepare it for transport and reinstallation by following the uninstallation procedure. See OPT100 User Guide for details.

2.8

Installation site requirements

DGA monitor can be installed and successfully operated in a wide variety of environments. Note the following special considerations:

OPT100 Installation Guide M211857EN-K

• Cold environments: Trace heating elements and thermal insulation may need to be placed over the exposed sections of the oil pipes. Required heating power and insulation thickness depends on the pour point of the transformer oil that is used. Temperature of the oil in the lines must exceed the pour point with a reasonable margin in order to keep the oil ﬂowing normally during operation.

• Hot environments: Weather shield installation option will reduce the solar radiation load on the DGA monitor. Consider placing the DGA monitor in a location that is not exposed to direct sunlight.

• Operating altitude: DGA monitor is intended for use in altitude range -1000 … 3000 m.

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. Measure the amount of cable and oil pipe needed.

2.8.1 Installation location of DGA monitor

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.

• The location must be safely accessible from the ﬂoor without the need to climb or reach.

• 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 is used, there must be a level concrete surface that is at least 100 mm thick.

If you have many suitable locations, prefer the following:

• Locations that are protected from rain and solar radiation.

• Locations where the vibration and heat from the transformer are not directly conducted to the DGA monitor.

2.8.2 Recommended locations of oil connections

DGA monitor needs to pump oil out of the transformer and return it after each measurement cycle. It is important that the oil is clean and from a representative location in the transformer, and the same oil volume is not measured repeatedly.

The oil volume needed for a single measurement cycle is slightly more than one liter. To make it possible to pump a new sample and return the measured oil without mixing them up, you must build two oil lines between the DGA monitor and the transformer. Consider the following when selecting the locations of the oil connections in the transformer and preparing for the installation:

• The recommended arrangement is to use two valves in dierent locations on the transformer. This improves oil circulation inside the transformer and prevents the returned oil from immediately mixing with the next sample.

Chapter 2 – Planning the installation

• Use the same valve for oil intake that has been previously used to take oil samples. This makes the measurements results of the DGA monitor more comparable with previous laboratory analysis results. After the oil lines are connected, you will not be able to take oil samples from the valves. Consider adding a new sampling valve to the intake oil line if you need to continue taking oil samples.

• Check if the transformer circulates its oil by forced convection. Oil ﬂow inside the transformer makes the sampled oil more representative of the overall oil volume. It is also useful if you have to use two valves that are close together, as it carries the returned oil away from the valve.

• It is possible to use a T-joint to connect both lines to a single valve but the T-joint must be close to the transformer − no farther than one meter (3 ft) from the valve. If a T-joint is used, the transformer should be of a type that circulates its oil.

• Check the type of connection thread on the valves, and make sure you have appropriate adapters for connecting the oil lines to the valves.

• The maximum allowed length of an oil line is 10 m (33 ft).

Some typically available locations of oil connections are presented in Figure 1 (page 13).

Figure 1 Possible locations of oil connections

Oil reservoir. Do not use.

1 2 Side of the oil tank, top level. Suitable location for oil connection if the valve is under oil

level at all times.

3 Side of the oil tank, high enough from the bottom to enable proper oil movement. Suitable

location for oil connection.

4 Radiator and its pipes. Suitable location if there is guaranteed continuous oil ﬂow in the

radiator. Not recommended if there is no forced circulation or circulation is not continuous.

5 Drain valve of the oil tank. Not recommended due to risk of sludge and free water.

Measurement from the bottom of the tank is also not representative for moisture measurement.

OPT100 Installation Guide M211857EN-K

CAUTION!

sludge or free water present.

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.

• There are no ﬂow direction control valves on the oil lines.

Operate the selected valves and make sure the oil is clean with no

2.8.3 Network security

DGA monitor is intended to be connected to a secure SCADA network that is appropriately protected against security threats. Do not connect the DGA monitor directly to the Internet.

The second Ethernet port of the DGA monitor (marked ETH1) is for temporary local use only.

2.9

Regulatory compliances

OPT100 DGA monitor is in conformity with the provisions of the following EU directives:

• EMC Directive

CAUTION!

Also account for possible vibrations and other sources of additional mechanical stress. Use anchors or bolts that are suitable for the wall material at the installation location. Note that they are not included with the Wall Mounting Set.

1. Attach one of the installation beams to the mounting location, at a height where you want the top of the OPT100 cabinet to be. Make sure it is securely attached from at least two points, and can bear the full weight of the DGA monitor.

2. Attach the second installation beam at the height of the second set of mounting holes.

3. Attach screws with washers to the top mounting holes of each pair on the sides of the OPT100 cabinet (four screws in total). Tighten them enough to safely bear the weight of the cabinet but not all the way in. The second hole of each set must remain free at this point.

4. With two people lifting, lift the OPT100 cabinet up and hang it from installation beams by the screws. If the lower installation beam is not at the correct height, re-attach it at the correct height before attempting this step again.

5. Tighten the four screws to secure the cabinet in place.

Use enough anchors or bolts to ﬁll local safety factor requirements.

6. Add a second screw (with washer) below each of the installed screws, and tighten them. The cabinet is now secured to the installation beams by a total of eight screws.
