SELCO T-Line Generator Control, Protection and Monitoring

Open the catalog to page 1

Selco T-Line The Selco T-line offers a complete range of system components for generator control, protection and power monitoring. The units are for DIN rail mounting or screw mounting in switchboards. Since the units are working on identical principles and have similar design and adjustment schemes, they are easily installed or replaced. All units are available in a number of versions varying in supply voltage and other functions, hence meeting specific customer requirements to a large extend. Synchronizing and load/power control The SELCO T-Line range includes various Auto Synchronizers...

AUTO SYNCHRONIZER^-. The T4000 performs automatic synchro- nizing of an incoming generator with electronic speed controllers in a mini- mum of time, by controlling the genera- tor speed and the phase between the The unit has fixed and variable output for adaptation to a wide range of elec- tronic speed controllers. The T4400 is a load sharer for genera- tors with electronic speed controllers. It includes a built-in frequency control and an integration function, providing a very high overall stability and compensate for any drift within the engine speed A soft load/unload function is also...

The T2700 is intended for detection of power level for protection, control and monitoring purposes. The relay detects the magnitude of the power and, when the preset value is exceeded, an output relay will be activated after a preset time delay. T 2800 Overcurrent or Earth Fault Relay The T3000 is intended for effective frequency monitoring on generators, busbars or other distribution systems. The relay contains the functions “under frequency” and “over frequency”, time delayed, and 2 individual output relays, one relay for each function. The T3200 is intended for continuous insulation...
