What fixation method is required You are here ATL Air-Cells, COPS Bags, Conservators & Compensators For over 2 decades, ATL has been producing Air-Cell Conservator Bladders/Bags, COPS bladders (constant oil preservation system) and collapsible “compensators” to control the expansion and contraction of dielectric transformer oil. ATL's dielectric fluid expansion systems isolate transformer fluid from the atmosphere, preventing air and moisture contamination. These bladders, sometimes called transformer conservator membranes are available in standard Westinghouse and GE sizes, as well as in custom configurations to fit any transformer or conservator tank. ATL's Conservator Bladders feature heavy duty rubberized- nylon construction, precision hard steel flanges and fittings, plus immunity to ozone, petroleum and high te...

Also, you will notice an absence of transformer protection relay. I have written about it few times about a year ago ( If you find anything missing in this list below, feel free to sharpen the pencil and leave the comment ;) Ok, here’s the list of the ten accessories I’m talking about: • • • • • • • • • • Figure 1 – Liquid Level Gauge A liquid level indicator is provided to aid in the systematic inspection of the transformer under load. It consists of a float-arm inside the tank, an indicating pointer and a magnetic coupling between the two across a liquid-tight separation. The gauge may be furnished with SPDT (Single Pole Double Throw) alarm contacts to give a remote annunciation of low liquid level. For contact wiring and terminal points, see the accessory connection diagram furnished with the transformer. Figure 2 – Liquid Temperature gauge The temperature gauge is furnished to indicate the top liquid temperature in the tank in degrees Centigrade. The temperature-sensitive element is mounted in a leak-proof well, permitting removal of the thermometer without lowering the oil level. The device is furnished with an additional red pointer to show the highest temperature attained since the last reset.To reset the maximum indicator, turn the knob in the center of the dial. The thermometer can be furnished with two SPDT contacts for a high temperature alarm, for energizing a fan circuit or for a low temperature alarm. For wiring and contact settings, refer to the schematic fu...

Conservator Tank One of the disadvantages of the Hence cooling and insulations are two important operations of the transformers. This is achieved by the transformer oil. The transformer oil circulates within the main tank and provides cooling to the windings. For efficient operation, correct levels of oil must be maintained through the operation, which is done by a conservator. Purpose of Conservator Tank The main purpose of the conservator tank is to maintain the transformer oil in the main tank. Oil which is required for cooling and insulation of the transformer windings circulates around the transformer windings. The transformer windings are placed in a tank that is full of transformer oil. When the transformer operates, the transformer dissipates the heat losses in the windings. This heat is absorbed by the transformer oil. This how transformer oil cools the transformer windings. In this process, the oil gets heated up and the hot oil must be cooled immediately. The cooling of the oil is done by different methods like natural cooling, forced cooling, etc. When the transformer oil heats up, its level increases and the hot oil is transferred to the conservatory. The oil level maintenance is achieved by a conservator. The Function of the Conservator Tank of a Transformer The main function of the conservator tank is the regulate and maintain the oil levels in the transformer. The conservatory is attached to the main tank of the transformer in which oil circulates and cools...

When an internal fault occurs in an oil-filled transformer not protected by the TRANSFORMER PROTECTOR (TP), the electric arc produces a large amount of explosive gases. Those gases quickly create an overpressure that leads to transformer tank explosion. The tank cover is often damaged, opened, and the explosive gases being in contact with air (oxygen) causes a fire. Unfortunately, the conservator oil generates a transformer tank overflow, which cause the fire to spread on the ground to the surrounding equipment and afterwards to the whole plant. The CONSERVATOR SHUTTER function is to isolate the conservator tank when an excessive flow is detected. This prevents the conservator oil from feeding the transformer fire. The CONSERVATOR SHUTTER is important for transformer safety and recommended by organizations such as IEEE, CIGRE, etc. A properly designed CONSERVATOR SHUTTER must: • Close to prevent flow from the conservator to the main tank when a catastrophic tank rupture occurs • Stay open to allow flow due to contraction of the oil volume during normal power variations and weather changes The TPC CONSERVATOR SHUTTER, TL type, is: • The sole TP shutter available in the market that has been tested under transformer rupture of insulation, a live test certificate is available on request • Self-contained, wholly mechanical • Ready to operate without commissioning setting • Including testing lever for easy operation • Equipped with an integrated magnetic switch; then, when the T...

Oil-immersed conservator tank transformer Factories, hotels, Employs the latest technology with high quality enamel coated copper conductor windings utilized in both sides of the coil. Transformer mineral oil is used as an electrical insulation and to assist in heat dissipation inside the transformer tank. A conservator tank is installed to accommodate the expansion of the transformer mineral oil which makes this transformer design suitable for large, higher capacity (kVA) transformers which use higher volumes of transformer mineral oil. Air in the conservator tank is allowed to escape or be re-introduced to maintain transformer tank pressure equilibrium via a dehydrating breather – a filter where a combination of silica gel and transformer mineral oil traps moisture and dust. High efficiency ventilating radiator fins are attached to the transformer tank which can bear the heavy weight of the transformer mineral oil. The transformer is also equipped with standard protection equipment such as a Buchholz Relay (a gas and oil actuated safety device which detects and warns of transformer faults), a Thermometer (which detects and warns of excessive temperature increases) and a Pressure Relief Valve (which releases excessive pressure build-up inside the transformer tank to prevent the transformer tank from being deformed). Product Feature And Benefit Conservator tank transformers have a similar design structure as power transformers used in a utility’s substation and : • have th...
