The infrequency of power outages in most developed countries, and the rarity with which standby sets are called on to run ‘for real’, make regular proving essential if sets are to operate reliably when needed. In recent years, blackouts in Europe and the U.S. will have been an uncomfortable reminder of this to the many organisations who did have standby generators that failed to work ...

Most ships have a chilled water system, which circulates cool water throughout the vessel, used for both air conditioning and equipment cooling. It is usually straightforward to incorporate resistors of the type shown into these ...

Load Banks for standby generators and uninterruptible power supplies. Cressall’s medium-voltage load banks installed in central London, act as test and exercise loads for standby generators and uninterruptible power supplies. These were challenging installations because the specification required the loads to add no additional noise to that from the generating sets ...

For high current ratings the most suitable earthing resistor element is the type RP oval edge-wound coil. RP resistors are manufactured from a continuous stainless steel strip, wound edgewise into oval coils. Each coil is supported by ridged ceramic insulators mounted on a stainless steel centre support, with stainless steel terminals welded at each end. This arrangement allows free expansion and ...
