SQ 0104

The SQ 0104 is a microprocessor-based synchronising unit. It is intended for a phase difference measurement between a bus bar and generator. It can be used in any kind of installation where a manual or semi-automatic synchronising is required. Circular set of 24 LEDs represents a phase difference. A lit LED displays momentary phase difference D j with a resolution of 20°el.(red LEDs). Within synchronising range ± 15°el., the resolution is increased to 5°el. (green LEDs). The instrument samples a generator and bus bar voltages using A/D converter inside a microprocessor. Both voltages are galvanically separated with measuring transformers. A synchronising condition is set, when the phase difference and the voltage difference between UGEN and UBB, for a time of delay, are within the set limits. The synchronising check relay is then switched on and a SYNC LED is lit for a preset pulse time (e.g. 100ms, 300ms).
