Royal Decree 1890/2008 on the regulation of energy efficiency in public lighting installations, defines for this purpose, the application of double lighting levels in outdoor lighting (see page 45995 attached).

Sodium vapor lamps.

Calculation of savings

10 LAMPS OF 150W SODIUM STEAM
Operation: 8 hours.
1.5 KW x 8 hours = 12kWh (connected to 230 V).
Reducing the supply voltage to 190 V.
The consumption of a sodium lamp at 190 V is approximately 67.5% (saving 32.5%).
12 kWh x 32.5% = 3.9 kWh (per day).
3.9 kWh x 365 days = 1432.5 kWh.
1432.5 kWh x 0.14 € / kWh = 199.29 € annual savings.

CONSUMED POWER AND INTENSITY OF LUMINOUS FLOW FOR A HIGH PRESSURE SODIUM LAMP
Tests for a 70W lamp.

The lamp of 70 W at 230 V consumes 88.61 W, (the additional reactance must be considered) and gives its assigned luminous flux considered 1.0 pu (one per unit 100%).
When the power supply is reduced to 190 V, the luminous flux is reduced by half (0.5 pu). The power consumed at this voltage is 59.8 W, which represents a saving of 32.5%.

10 LAMPS OF 150W MERCURY STEAM
Operation: 8 hours.
1.5 KW x 8 hours = 12kWh (connected to 230 V).
Reducing the supply voltage to 208 V.
The consumption of a mercury lamp at 208 V is about 80% (saving 20%).
12 kWh x 20% = 2.4 kWh (per day).
2.4 kWh x 365 days = 876 kWh.

The transformers are manufactured in compliance with IEC 60076-13 and, IEEE C57.1201 (or other required) standards.
The core is made of magnetic sheets with high permeability and low loss rate with a joint assembly of 45º with cooling channels.
All the winding of conductors is made of electrolytic copper of E-CU 99.9%.
Depending on the design of the transformer, the winding can be continuous or with a disk at intervals, with multiple or simple propellers.
The cooling channels are made with properly formed rods and with guide rings.
The derivation occurs in the HV winding, controlled either by a switch or by a bypass transformer.
The windings are autoclaved to reach the exact dimensions and avoid successive failures of lack of elasticity. All the transformer is fitted in the tank and filled with oil in isolation. The tank, normally, is of the vacuum type.
The refrigeration is carried out by means of radiators: mainly bolted, of the removable type; Sometimes it is soldered.
You can use fans or pumps to increase the operation of the transformer.
The transformers are capable of operating at a power greater than the rated power based on the IEC 354 standard.
When the problem of dimensions does not allow to deliver the transformer with the isolated liquid, the tank is carried with inert gas, or the radiators and the conservator are delivered disassembled.
The transformers can be equipped with specific accessories in addition to the standard ones, such as overpressure valve, diaphragm conservator, amperometric transformers, winding temperature indicator, cable box, centralization, etc.
When required, the assembly can be carried out by our specialized personnel.

TECHNICAL CHARACTERISTICS:

RULES

The transformers are made according to IEC 76 standards.

NUCLEUS

It is built with magnetic sheet with oriented crystals, cold rolled and isolated on both sides by means of a thin layer of insulating varnish (Carlyte). The assembly is made with joints interspersed with 45º cuts. The suitably closed assembly ensures a very low noise operation,

ARMOR

In wood or steel bars, according to the construction project, always of adequate dimensions. Vertical holes that allow perfect protection to avoid damage from short circuits.

WRAPPING

In electrolytic copper, isolated with pure cellulose and therefore able to withstand all atmospheric surges. The perfect circulation of the oil, also the interior of the coils, is ensured by means of large channels obtained by means of corrugated and folded cardboard. Before they are assembled, the envelopes are dried and impregnated.

TANK

Structure of welded and reinforced steel, internally painted with varnish indissoluble in the presence of oil and externally corrosion proof. Standard execution with radiators and corrugated steel sheets.

INSULATORS

In dark porcelain, according to the UNEL standard. Easily replaceable when they break.

STANDARD ACCESSORIES

Preserved in oil, oil level indicator, oil filler cap and oil discharge, internal overpressure output device, air dryer connection, thermometer, grounding, loops, rotating slide rollers, switch for regulating high voltage overload .

LOW ORDER ACCESSORIES

High voltage connection boxes, thermometer with electrical contacts, Buccholz relay, sicilagel dryer, switch for regulation of high voltage plugs, auxiliary box.

INSTALLATION

Inside or outside

TESTING

All transformers are tested with routine tests established by the IEC 76 standards. On request, shock wave resistance tests can also be carried out. Special tests to resistance of short circuits.

STANDARD

The transformers are built in accordance with IEC 726 standards.

CORE

The core is built up of cold rollled oriented grain steel sheet with low specific losses, insulated on both sides by a thin inorganic coating (Carlyte). The sheets composing the core are cut at 45 degrees. Uniform pressing, stiffnes and solidity of the columns assure a low noise level.

MEDIUM VOLTAGE WINDINGS

The high voltage are made of  electrolitic aluminium conductors (wire or foil strip depending upon power and voltage requirements). It is possible to produce copper windings. The windings are inglobed under vacuum in class F epoxidic resin. The accuracy of execution of these processes allows the obtainement of windings free from partial discharges.

LOW VOLTAGE WINDINGS

The low voltage windings are made of strip or foil (copper or aluminium conductor depending upon power and voltage requirements). Class H insulating material is used.

STANDARD ACCESSORIES

Skid under base or truck with bidirectional wheels; Lifting lugs; Earthing terminal.

OPTIONAL ACCESSORIES

Thermometer dial type whith electric contacts; Temperature monitoring unit without display; Temperature monitoring unit with display; Cubicle IP 315 or other; Forced ventilation system.

TEST

All transformers are singulary tested with routine test, according to standard IEC 726. Upon request the following type test can be carried out; temperature.

CLARKIA transformers have been designed and manufactured strictly in accordance with standards IEC 60076-6.

Coils:

Coiling is made of copper class H-Grade 2/thermal class H.200, according to IEC 60317-3.
Insulation varnish for this copper is a polyester-IMIDA modified THEIC with a polyamide-IMIDA overcoat. This kind of winding wires are homologated according to UL-E103536 (NEMA MW-35C).
All our coils lack insulation boards, which makes them very reliable for humidity in tropical and marine climates, etc…
Insulation is achieved through fiberglass separators class F.
Coils have been designed and manufactured for use in a room temperature of 45ºC with insulations class F (155ºC) and a class B temperature increase (70ºC), always considering the continuous operation.
Optionally, copper strips can be also used.
All coils can carry additional regulation intakes +2,5%, -2,5%, +5%, -5%,etc… upon customer request.
