Carroll & Meynell Transformers Transformer Design and Manufacture

Carroll & Meyer lead

Carroll & Meynell designs and manufactures transformers from 20VA panel transformers up to 20MVA power distribution transformers: single phase and three phase. Our customers include those in construction/engineering, transport/traction, mining, offshore/subsea and electrical wholesalers.

Cast resin transformers and oil-cooled transformers

We are the UK and Ireland distributor for ‘Tesar’ Cast Resin and oil-cooled distribution transformers, successfully servicing various markets for many years. For Cast Resin products we can offer standard or customised transformers.

Standard distribution transformers can be supplied up to a rated power of 3150kVA and insulation levels up to 36kV; typically these have aluminium windings.

Customised transformers can be copper or aluminium wound and are primarily presented to offer solutions to clients with specific needs concerning installation and application.

The following transformers are considered customised products:

  • Transformers with rated power from 3.15MVA up to 20MVA
  • Rectifier transformers
  • Transformers for photovoltaic and wind power applications
  • Transformers for ACDC conversion for industrial application and electric traction
  • HV HV transformers

Tesar Cast Resin transformers are designed to withstand the worst climatic and environmental conditions.
We can also offer the following accessories: IP-rated enclosures, force ventilation fans, surge arrestors and anti-vibration pads.

Current transformers

Our products are designed in accordance with British (and European)standards for metering and protection applications (including Class PX). We also possess expertise in designing to American and Australian standards.

Our products feature torroidal core construction and precision layered windings with fully interleaved insulation to protect from high inter-turn voltages.

We can offer a variety of different finishes dependant on the final application and location:

  • Self-amalgamating tape wrap for locating in air CT chambers of switchgear/transformers
  • CTs for use in oil, midel, compounds are finished in reinforced nylon tape and sealed with two-part epoxy resin
  • Polyurethane encapsulation for outdoor weatherproofing and robustness, slip-over and bar-primary moulds available

Each CT is provided with a comprehensive test certificate showing all errors/performance from measurements using up-to-date automatic test equipment.

Bespoke air-cooled transformers

We design bespoke air-cooled transformers according to individual application requirements.

Isolation transformers have concentrically wound coils with a safety earth screen between primary and secondary windings. Autotransformers are also available with common winding.

The bespoke air-cooled transformers can be single or three phase, up to 800kVA rating for dry type transformers and open style or enclosed for indoor/outdoor installation.

Options include: protection fuses/MCBs, plug/sockets, isolators, meters, special applications, korndorffer motor-start, k-factor (harmonic tolerance), open-delta and rectified output.
