Cressall Resistors, has designed a resistor that operates at 132kV and can withstand a high-voltage impulse of up to 650kV. Furthermore, because it’s intended for use in Australia, it can survive an earthquake or cyclone on an epic scale. Here, Martin Nicholls, Sales Director, Cressall, explains how finite element analysis (FEA) helped ensure that the construction would withstand the most tempestuous elements.

Resistor manufacturer Cressall has developed a cost-effective range of neutral earthing resistors (NERs) designed to help generator manufacturers and end users around the world protect distributed generation systems. The NERs have been specifically designed to be supplied with multiple vacuum contactors, for applications requiring the earthing of multiple parallel-connected generators.

  Cressall have designed a resistor to safely withstand the mechanical and thermal stresses of the 48MJ that is applied for 0.25s at the switch-on of HVDC systems using voltage source converter technology.

Cressall Resistors has worked with training provider Focus Management for Business to deliver a set of NVQ training programmes in business improvement techniques for its plant floor team. 

Leicester based power resistor manufacturer Cressall marked a hundred years of successful business by inviting local UK MP Jonathan Ashworth to visit the factory and discuss the challenges and opportunities the company has experienced over the years. Cressall's managing director, Cy Wilkinson, and the Leicester South MP discussed the challenges of recruiting specialised staff, maximising exports and the status of manufacturing in t...
