Pressure Relief Devices_ MBT Oil-Immersed Transformer
A pressure Relief Device is one of the important accessories installed on the transformer. Let’s discover more about them.
Three-phase Transformer Connections
The connection of the primary and secondary winding of a three-phase transformer can be designed in different ways according to the desired application and available terminals.
The important role of the transformer maintenance
The purpose of transformer maintenance is to ensure all parts of the transformer and accessories be kept in good condition.
Equivalent Circuit of Transformer
The equivalent circuit diagram of a transformer is a simplified circuit in which the impedance, resistance, and leakage reactance of the transformer can be more easily calculated.
Polarity Test of Transformer
The polarity can be defined as the induced voltage direction in the primary windings and the secondary winding. If two transformers can be connected in parallel, then the polarity must be identified for a good connection of the transformer.
THE MOST COMMON SWITCHGEAR-BASED SUBSTATION TYPES
This article will introduce a few most common types of MV/HV power substations based on the type of distribution switchgear, which can be seen in every distribution network. There are a number of methods of construction of substations depending on the switchgear type.
Open Circuit and Short Circuit Test of Transformer
The open-circuit test and the short-circuit test are performed on a transformer to determine the equivalent circuit of the transformer, the voltage regulation of the transformer, and efficiency of the transformer.

What is a Transformer Rating?
Transformers are designed based on the rated voltage and current required for the transformer’s operation.
Acidity Test of Transformer Oil
For the oil-immersed transformer, the transformer oil plays a vital role in insulating and cooling. Therefore, the Acidity Test of Transformer oil is a very essential test for analyzing the oxidation of transformer oil.
Oil and Winding temperature Indicator of the transformer
Oil and Winding temperature Indicator are types of accessories that are used to protect the transformer operation process.
Accessories of dry type transformer
The dry-type transformer is a completely stationary solid-state device and it requires less maintenance to provide service with few failures. Unlike liquid-filled transformers, this transformer uses only high-temperature insulation as they are very environmentally safe.
THE MAINTENANCE OF CAST RESIN TRANSFORMER
A cast resin transformer is the most important and expensive electrical equipment in a power substation. Therefore, to achieve optimum performance and extend product life, it is best to conduct periodic maintenance checks on your machines. This article will guide you on how to maintain your transformer.
