Key information on the plants

Oil capabilities at outlet of the plants, as a rule, are provided while single oil passing through the plant with

the following oil capabilities at inlet: moisture content not more than 50 ppm, air content not more than 10,5%,

class cleanliness according to ISO 4406 at least –/18/16, content of mechanical particles not more than 80 g/t.

However if your oil capabilities are worse than the capabilities specified above, the plants will provide the

required capabilities at outlet, but for this more time will be required for oil preparation (purification).

Oil drying

Oil drying is performed in the vacuum chambers through thermal vacuum method with preliminary oil

heating up. For efficient drying they use two decanting vacuum chambers with a special spraying and controlled

nozzle system, providing optimal spreading behavior of oil with thickness smaller than 1 mm. Oil level in the

vacuum chamber is being maintained automatically.

The vacuum equipment used is as follows: rotary vane vacuum pumps or vacuum systems consisting of

rotary vane vacuum pump and vacuum pump Roots.

Oil filtering

In the plants, as a rule, there provided three-stage filtering. The first stage: inlet filter with filter fineness of

100-200 micron, second stage - preliminary treatment with filter fineness 25-50 micron, third stage – final

treatment with filter fineness 3-5 micron. Filtration factor of such systems is not less than 400.

Contamination control of filtering elements is performed by way of measurement of pressure drop or by

any other way.

Oil heating

The heaters of transformer oil are manufactured with direct or indirect oil heating. Capacity of the heaters

of oil is from 40 to 240 kW. Capacity of the heater of the specific plant is designed so that the heater provided oil

heating up to the required temperature at nominal capacity. Specific surface capacity of oil heaters is smaller 21,2 W/sm .

Control and instrumentation devices

Control and instrumentation devices of the plants perform checkout of parameters, provide normal

operation of the components parts of the plants, as well as perform locks preventing operation at emergency

modes.

The plants, providing oil preparation with its direct hearting, have locks of the emergency modes, control

and maintain the parameters as follows:

Control and maintain oil temperature;

Make control of oil pressure at outlet and outlet of the plants;

Regulate automatically oil heater capacity to maintain oil temperature at preset mode;

Disconnect automatically oil heater in case of exceeding over the preset temperature;

Perform automatically shutdown of oil heater at absence of oil flow, as well as provide impossibility of

activating of the oil heater at oil flow absence.

In the plants, providing oil preparation, there performed smooth efficiency adjustment from 10 to 100%.

Plants for oil degassing, as well as the plants for drying of solid insulation of power transformers and

reactors have possibility of control as follows:

Residual pressure and inleakage in the vacuum chamber (cooler of the plants «ETMA Iney»);

Residual pressure being produced with vacuum equipment, inleakage, temperature of windings in

transformer (at completion of the plants with SCTV system).

The scope of delivery includes:

installation in accordance with the Purchaser's order;

documentation, providing possibility of studying of the plant and possibility of the further independent

work for it;

documentation for bought-out and component parts of the plant;

set of spare parts, providing operability of the plant for the warranty service period.

The plants ETMA UVM, ETMA UVS, ETM UVSE, ETMA NTML, ETMA NTM, ETMA URTM, «ETMA Iney»,

«ETMA Suhovey» etc. can be manufactured with automatic control. In this case the Plant control is carried out with help

of hardware and software system on the base of controller and color touch-control operator's switchboard with size of

10 or 15″. Hardware and software system provides manual and automatic Plant control.

Control of oil pumps, vacuum pumps, oil heater, air heaters and other elements is performed with starters

through controller. Depending on the control mode having been selected closing (opening) of the valves is performed

manually with touch-control board or in the automatic mode at preselected program of the appropriate mode.

Manual control. Operator has possibility to control actuators of the plant (pumps, valves, haters etc.) directly from

the operator's switchboard. With this parameter check when the Plant operating in this mode is carried out by the

operator.

For instance, for the Plants ETMA URTM the operator's switchboard with control circuit will be shown as follows:

Аutomatic control. Operator should select one of the Plant operation modes, after which the Plant self-performs

selected mode and disconnected after preselected criteria of the work completion (time, quantity of used oil etc.). At

automatic control all the parameters required to perform the selected mode are maintained automatically. When

deviating of the parameters from the set ones, or when finishing of the Plant operation, the appropriate messages are

being formed on the operator's switchboard, being duplicated with audio alarm.

At both manual and automatic control, visualization of the process parameters is carried out directly from the

operator's switchboard.
