In order to meet the increasing demand for safety standards in modern industries, many end-users are looking for methods to eliminate the need for electrical staff to open MCC cubicles in order to determine the nature of a motor trip or to adjust motor protection setting parameters.
NewElec’s KE range protection relay can have an optional door mounted fault indication display as well as an infrared data acquisition and transfer facility (IRDA) that is both inexpensive and easy to use. A transceiver IRDA is simply attached to a communications cable that connects to a laptop. The housing on the IRDA is magnetic to fasten to the door mounted RDU so that the operating staff may adjust, read and save data directly.
The KE is an advanced motor protection relay that is also capable of recording real versus apparent power utilisation for analysing motor efficacy. It has outstanding protection benefits that include earth insulation lockout, user selectable instantaneous or IDMT earth leakage tripping characteristics, programmable limitation to start attempts and up to 2000 event records as well as a separate listing of the last 60 faults together with current and voltage details.
In flameproof applications, the IRDA saves time since the flameproof door need not be removed to achieve the results mentioned. For utilisation underground, NewElec has developed an explosion proof version of the IRDA that allows the operator to download motor information to a USB memory stick device.
