2. General

SG10 type-this series dry-type distributing transformer has strong withstanding of thermal shock, overload capability. Beside, it has many good points such as flame-retardant, low-loss, and low partial discharge capacity, low noise, no harmful gas and no pollution. It is insensitive of humidity and dust, compacted, no crack and so it is easy to be maintained. Therefore, it is suitable for the using in the adverse circumstances of high requirement for fire protection, high degree of load fluctuation and dirty, moist, such as airport , power plant, metallurgy, hospital, skyscraper, shopping center, and residential areas and other special environments like oil, chemical industry, nuclear plant, nuke, etc.

Q:50KVA transformer each phase current maximum band
Normal current does not exceed 72A per phase current. Of course, in the event of an accident or to strengthen the transformer cooling can be short-term overload operation.
Q:Is the transformer output DC or AC?
There is also a direct communication, depending on what is the use of what. For example: for power distribution with the step-down transformer input and output are AC; and electronic circuit transformer is a double winding or multi-winding transformer, mostly safety transformer, the output is DC; China's auto-transformer is AC transformer The Autotransformers are not allowed to be used as safety transformers. So the output for the exchange.
Q:What is the unit of the transformer?
KVA instead of KW? VA or KVA is the apparent power, AC line used, also known as the capacity, that is, voltage and current rms product, the unit ... but will affect the load design of the transformer, so use VA or KVA to calculate more accurate. And W or KW is our usual habit of the law, written formal.
Q:50 What is the actual power of the transformer? Is 3 phase 50 or 3 together 50
Three-phase transformer marked the basic capacity of three-phase capacity, that is, the sum of three-phase winding capacity is 50KVA. The actual output capacity of the transformer, not only with the rated capacity of the transformer has a relationship with the nature of the load, and the power factor of the load, and the efficiency of the transformer has a relationship with the level of loss of the transformer. When the load balance, stability, pressure efficiency of 100%, the actual power can be achieved: P = Se × COSφ, visible higher power factor, the closer to 1, the transformer the actual power is higher, closer to the apparent power. In general, the 50KVA transformer, when the power factor of 0.85, the actual output power of about 42.5KW.
Q:315KVA transformer high-voltage side need to use the specifications of the high-voltage cable
To the formula high-voltage side rated current = 315 / (1.732 * 10) and then check Kazakhstan with the wire rated current know the choice
Q:What is the transformer capacity ratio? Capacity than 100%.
The ratio of the maximum capacity to the minimum capacity. The ratio of capacity to 100% is the ratio of maximum capacity to minimum capacity of 1: 1.
Q:Transformer charging
There is a megger, that is, shake the table, with a handle, used to measure the electrical insulation meet the requirements do not,
Q:Altium designer DXP transformer in the same name how to change?
I am only familiar with PROTEL, PROPERTIES I am not familiar with
Q:50KVA transformer maximum load is how much?
Transformer output power is apparent power, and active power (KW) relationship: apparent power = active power × power factor. The average power factor of 0.8, 50 KVA transformer can be load power (50 KVA × 0.8) 40KW of active power.
Q:What is a transformer paused?
5. Users who charge the basic electricity charges according to the maximum demand shall apply for the suspension of all the capacity (including high-voltage motors that do not pass the receiving transformers) and comply with the relevant provisions of Clauses 1 to 4 of this Regulation.
