 How to choose the model and specification of oil-immersed three-phase distribution transformer according to load capacity?


Selecting a Transformer Based on Load Capacity:

Calculate Total Load Power:

  • First, it is necessary to determine the total power of the loads to be supplied. For residential areas, this involves considering the total power of all household electrical appliances, including lighting fixtures, televisions, refrigerators, air conditioners, etc. For example, in a residential area with 100 households, if the average power consumption per household is 5 kW (considering the simultaneous use factor), the total load power would be approximately 500 kW.

  • In industrial settings, it is necessary to tally the power of all production equipment, lighting, and office devices within the factory. For instance, in a small mechanical processing plant, the total power of machine tools might be 300 kW, and adding the power of lighting and office devices, the total load power could reach around 350 kW.

Consider Simultaneous Factor and Power Factor:

  • The simultaneous factor refers to the probability that all loads will operate simultaneously at any given moment. In residential areas, the simultaneous factor is generally between 0.4 and 0.6. In industrial settings, it is determined based on production shifts and equipment operating patterns, typically ranging from 0.7 to 0.9.

  • The power factor reflects the efficiency of energy utilization by the load. In scenarios with a high proportion of inductive loads (such as motors), the power factor is lower, usually between 0.7 and 0.9. It is essential to calculate based on actual load conditions and then select the transformer capacity based on the calculated actual load capacity.

What should be noted when selecting and installing GIS voltage transformers?
In power systems, voltage transformers in GIS (Gas Insulated Switchgear) play a crucial role in voltage measurement and relay protection. Selecting the right model and installing it correctly is vital for the stable operation of the equipment. The following points should be noted regarding selection and installation.I. Key Points for Selection(1) Matching Rated ParametersVoltage Level: It must be consistent with the voltage level of the GIS system. For example, 110kV and 220kV GIS systems requir

1. Accident Overview1.1 Structure and Connection of 35kV GIS Switchgear Voltage TransformerThe ZX2 gas-insulated double-bus switchgear, manufactured in March 2011 and officially put into operation in July 2012, is configured with two groups of bus voltage transformers (PTs) for each bus section. The two PT groups of the same bus section are designed in one switchgear cabinet with a width of 600 mm. The three-phase PTs are arranged in a triangular formation at the bottom of the cabinet.The PTs ar

What Are the Steps for Error Testing GIS Voltage Transformers?
Hey everyone, I'm Oliver, and I've been working with current transformers (CTs) and voltage transformers (VTs) for 8 years.From assisting my mentor on site to leading high-voltage testing teams and conducting error calibrations independently, I’ve dealt with all kinds of instrument transformers — especially those used in GIS systems. The error test for voltage transformers is something I perform regularly.A few days ago, a friend asked me:“Oliver, how exactly do you perform an

Operation Method for PT Resonance in 500kV GIS Switching Station
1. Causes of ResonanceA 500kV GIS switching station is designed following the principle of “primary equipment intelligence and secondary equipment networking”. The PT high - voltage side has no disconnector and is directly connected to the bus GIS. Through the analysis of fault recording diagrams, when the 5021 circuit breaker opens, the fracture capacitance and PT form a series circuit. Moreover, the bus voltage, after being paralleled by the PT inductance, shows inductive character
