Transformers: just a dull grey box?
Transformers are often regarded as the least important element of the electrical network.
Contrary to this perception, the importance of transformers, and their role in the grid, far exceeds their traditional function of stepping voltage up or down, explains Pablo Castaño, BRUSH Product Manager:
“Transformers are a crucial element in maintaining a healthy, decentralized, flexible network, managing elements such as power factor, harmonics and fault level, for example by deploying natural or bespoke impedance values.“
Features and benefits
- High efficiency transformers based on EU EcoDesign Directive EU 548 and Tier 2 efficiencies
- Alternative cooling fluids including Midel and FR3 for environmentally sensitive or urban sites
- Low noise level transformers with advanced core build technology and variable speed fan options
- Designs are calculated for minimal Partial Discharge values through an optimised insulation structure that extends operational lifespan
- Condition Monitoring options via fibre optic temperature sensors & gas detection systems
- Compact transformer design reduces overall substation footprint enabling significant savings in civil costs
- Cooling methods ranging from naturally cooled to directed-oil via pumps and forced-air via fans
- Tapchanging by On-Load (bolt-on or in-tank) or Off-Circuit switching devices. Remote Tapchanger Control Panels can also be supplied
- Full range of accessories and protection devices available including digitally enabled options as well as condition monitoring equipment
