Multi-kW motors served by one starter

June 2012 Analytical Instrumentation & Environmental Monitoring

In the mining industry there is frequently a need to rate one starter for the highest kW motor that will be connected to it and to use the same starter for a variety of smaller motors. Gating box applications are an example. However the overload protection settings for the respective motors then also need adjustment if the smaller motors are to benefit from protection. This problem is compounded in flameproof enclosures because of the time taken to open the compartment door.

NewElec’s MA motor protection relay range combined with the programmable RDU 216 is the solution. The RDU 216 is able to store up to eight popular settings for different kW motors. The varied settings can then be downloaded to the MA protection relay at the touch of a couple of buttons. These are accessed through the flameproof door, which can be fitted with a window in order to see the RDU 216 MMI.

Keeping an eye on invisible radiation
Omniflex Remote Monitoring Specialists Analytical Instrumentation & Environmental Monitoring
At its peak in 1994, the energy generation capacity of the UK’s nuclear power stations was 12,7 GW across 16 plants. In 2024, the capacity has fallen to around 5 GW, and the number of stations is down to nine. However, this is far from the end of the story as spent nuclear fuel remains radioactive for centuries, and requires rigorous safety processes to safeguard against leaks.
