People Also Ask about

What is the use of CRGO in transformer?

Detailed Solution. CRGO laminations in a transformer are used to minimize both eddy current and hysteresis losses. CRGO is cold rolled grain oriented steel and as the name suggests, its grains (crystals) are aligned in the direction of rolling.

What is CRGO in transformers?

CRGO is the acronym for Cold Rolled Grain Oriented Steel. A material that is mainly used in the core of a transformer.

What are the disadvantages of amorphous core transformer?

Poor Overload Capacity. Because the saturated flux of amorphous metal is much lower than electrical steel, it is easy to be over excited. So the overload capacity of AMT is much lower than conventional transformer. 80% of load is dangerous for AMT, whereas the conventional transformer can run with 120% of load.

What is the amorphous transformer?

An amorphous metal transformer (AMT) is a type of energy efficient transformer found on electric grids. The magnetic core of this transformer is made with a ferromagnetic amorphous metal.

How to compute for transformer size?

To calculate the kVA rating for a single-phase transformer, you'll need to multiply the required input voltage (V) by the required current load in amperes (l) and then divide that number by 1,000: V * l / 1,000.

What are the advantages of amorphous transformers?

Advantages of amorphous core transformers: Better overload capacity. Excellent short circuit capacity. High reliability. Increased energy efficiency. Lower maintenance cost. Reduction in SO2 waste. Reduction in fossil fuel consumption. Savings on accumulated energy costs with cost-saving benefits to the business.

What are the specifications of a transformer?

. 1 The standard ratings of transformers shall be 100,200, 315, 630, 1000,1250,1600,2000 & 2500. 5.3 The windings of the transformers shall be connected to Delta on the primary side and star (Y) on the secondary side. The neutral of the LT winding shall be brought out to a separate terminal.

What is the difference between amorphous and CRGO transformers?

Amorphous core transformers have 70-80% lower no-load losses than CRGO core transformers of the same rating. However, amorphous core transformers have higher initial costs, require larger coils and tanks due to the lower saturation point of amorphous material, and are more difficult to repair.
