The dimensions of the subassembly are determined in accordance with customer requirements. Based on those dimensions one or more standard models are developed for the customer. These form the basis for future orders. Fixed dimensions means time savings for the customers design department, because designers do not have to keep making new designs. Also they do not have to wait for the Subassembly to be manufactured and delivered every time. Every Subassembly is manufactured to a high standard. The design can withstand mechanical loads and has a high vibration resistance.

All the transformers of one or more phases are brought together by manufacturer in the Subassembly. Each current transformer is then checked independently before assembly into the set. After assembly, the complete unit undergoes extensive testing. This eliminates measurement errors due to mechanical and electrical interference between the current transformers, if any. The test reports are available on the internet. If required, the connecting cables of this sophisticated current transformer unit are provided with color coding and on request with coding tags. The basic construction of the subassembly is completed with aluminum plates; however, a non-metal construction with transformer board is also possible.

The Subassembly is supplied in a special packaging. This is to prevent damage during transport and to protect it from dust and metal particles. Once the unit has been removed from the packaging, assembling is simple. The only tools the fitter needs are a screw driver for fitting the four threaded rods and a wrench for securing them. Guides in the subassembly and screw slots in the threaded rods ensure the assembly goes smoothly. The fitter has no need to lift heavy weight either, since the subassembly comes with mounting points for lifting lugs. And last but not least coded wiring prevents incorrect connection, so that it is only a matter of minutes before the unit is fully assembled.

Subassembly with test lead

The test lead is pressed between the plates and the CT, thus securing the fixation of the lead. This fixation is especially important for CTs near the bushing.

Non-metal subassembly

For an application in or near active parts. All parts including the plates and screw rods are constructed out of non-metal materials.

Special model in non-metal subassembly

The plates can be mounted using two holes on the corners of the subassembly. This solution has reduced the total cost of the CTs considerably.

.

Non-metal subassembly for three phases

A three phase system that will be mounted in the tank near to the active part of the power transformer. This design is based on customer drawings.

Double stack subassembly

A subassembly with different sized CTs. The total size of the subassembly is 1 meter. Used for protection of the sensible metering cores.

Subassembly with saturation transformer

According to IEC standards, sometimes there is a need for a low Fs figure. If the low Fs figure cannot be made by the core itself, a special saturation CT can be mounted on the outside
