According to the UK’s Climate Change Committee (CCC), the drive towards Net
However, a recent study by the German VDE highlights a concerning perception among young people who see electrical engineers as ‘bent over laying cables or installing Christmas lights’.This underscores the urgent need for reskilling and repositioning in the engineering sector. While governments and educational facilities need help presenting engineering in general, issues due to COVID and the general streamlining of workforces have seen fewer engineers being retained in job roles that require specialist knowledge of testing standards and requirements for applications as diverse as:
T
Motor Testing Where voltage tolerance, phase currents, and winding temperature can be measured.
Fuse/Switch/Cable Testing The variety of currents and standards these products must adhere to means that testing is essential and at the rated current. REO can also help with loads to provide necessary inductance levels if required.
Power for maintenance
Ships and trains have many tertiary systems, like HVAC, door activation, and passenger information displays; these require energy to perform maintenance functions, even when the Transformer-based power supply allows safe use, even in challenging environments.
Drive Testing
Allowing a slow power increase to capacitors (VSD) or substituting the DC link altogether allows environments.
Semiconductor/diode validation Reverse breakdown of diodes is often tested by increasing an applied voltage and measuring application of a voltage in test environments. REO has been utilising variable transformers since 1925, to provide robust control of AC voltages and currents. These transformers are preferred whenever smooth adjustment of output voltages at high currents and constant sine form is needed. REO’s variable column-type transformers use graphitized pure carbon rollers, which provide Multiple Columns can be series or parallel connected for increased voltage or current handling capacity. This versatility is not the independently of the brush position, and variable column-type transformers are not just designed for continuous operation; they can also handle high levels of overload.
Transformer can typically operate at ten times their nominal rating for several seconds, demonstrating their reliability and durability.

his transition will necessitate a proactive redirection of the workforce, particularly in key areas like electrical engineering.
This AC can easily be transformed into DC
the application’s requirements by incorporating and retained knowledge about rating, mounting, and application of complete systems, which customers can use with their equipment. REO variable transformers are usually motorised, so they can be adjusted to increase or decrease voltage or even regulate power according to changing load requirements. However, the use of large control wheels for adjustment has been superseded by the use of internationally recognised interfaces such as be provided as an additional option to allow the REO celebrates its centenary in 2025 and options for customers who require AC or DC voltages and currents. REO can generally manufacture turnkey testing solutions with power ratings up to 1 MVA (800 kW), voltages up to 12 kV DC, and currents up to 10000 A AC.
