PM cores are a variation on classic P cores, suitable for large high power transformers and energy storage chokes. They have larger wire slots facilitating easy assembly, but still the good shielding of a closed core shape.
PM cores can be found in transmission and radar equipment and in various high power industrial installations.
Transformer winding deformation test instrument based on the measurement of the characteristic parameters of transformer internal winding the internal fault frequency response analysis (FRA) method which is being developed in developed countries is adopted to make an accurate judgment of transformer internal fault.
After the design and manufacture of transformer is completed the line coil and internal structure are determined. Therefore for a multi-winding transformer line coil if the voltage grade is the same and the winding method is the same the corresponding parameters (Ci Li) of each line coil should be determined. Therefore the frequency domain characteristic response of each line coil is determined accordingly and the frequency spectrum of the corresponding three-phase line coil is comparable to some extent.
The distribution parameters of transformer windings will change when short-circuit between turns and phases occurs in the test process or collision occurs in the transportation process resulting in the relative displacement of the line coil and the deformation of the line coil caused by electromagnetic tension in the short-circuit and fault state during the operation process. Then it influences and changes the original frequency domain characteristics of the transformer that is amplitude change of frequency response and resonance frequency offset. The transformer winding test instrument developed according to the response analysis method is such a novel non-destructive testing equipment for transformer internal faults. It is suitable for the internal structure fault detection of 63kV ~ 500kV power transformer.

Three-phase transformers are used to convert the available 3-phase mains voltage into any load voltage.
To cater for the wide range of application areas involved,these transformers are essentially available in
the same kinds of designs as the single-phase transformers, e.g.
Three-phase dry-type transformer:
separate winding version
Three-phase series transformer:
autotransformer winding version
Three-phase safety, isolating, mains or
insulating transformer: separate winding version
In terms of how the 3 coils are connected, there are various options available and each of these provides
the transformers with specific properties. The vector group code is composed of the following elements:
The upper-case letter indicates the higher-voltage winding
(the highest voltage in terms of operation).
The lower-case letter indicates the lower-voltage winding.
The brought-out neutral is indicated by means of N or n
(depending on voltage level).
â?¢ The distinctive number indicates the phase angle of the lower voltage
in relation to the higher voltage (distinctive number multiplied by 30).
The following winding connection options are available
Delta: D, d
Wye (or star): Y, y
Zigzag: Z, z
Example: Dyn5
Higher-voltage winding is delta-connected.
Lower-voltage winding is star-connected with a brought-out neutral.

Product Details
It is the insulating sleeve that leads the transformer's internal high and low voltage leads to the outside of the oil tank, which not only insulates the ground as the lead, but also plays the role of fixing the lead.
Therefore, the transformer sleeve has the following requirements:
(1) it must have specified electrical strength and sufficient mechanical strength.
(2) must have good thermal stability, and can withstand the short circuit of the instant overheating.
(3) small appearance, small quality, good sealing performance, strong universality and easy maintenance folding.
Transformer bushing insulators are applied as a structure, carrying on conductor through a partition such as transformer tank and insulating it, incorporating the means of attached flange to the partition for medium voltage level.
For Entire Range of Bushings Ratings from - 1 Kv to 72 Kv & - 100 Amp. to 10,000 Amp.
All Ares Insulator transformer bushing insulators are made of ceramic materials according to IEC 672. Other Transformer bushing custom-made insulators can be supplied upon customer's request and specifications.
