The HAS-111DG synchroniser is applied to check the synchronisation conditions. The paralleling relay transmits a synchronisation pulse when the phase angle, frequency and voltage deviations are within the set limits. Besides this, the HAS-111DG is equipped with two analogue outputs. These outputs can be used for regulating purposes together with DEIF A/S load sharing units. Function : The HAS-111DG can be used in installations where manual or semi-automatic synchronising is required, or by using the ∆f and/or the ∆U output for automatic synchronisation of a generator island to another utility . Settings : The HAS-111DG is equipped with five potentiometers accessible from the front of the unit. Phase: Here the phase window for synchronisation is chosen. It can be set symmetrically or asymmetrically. Frequency: Here the max. slip frequency difference is chosen. It can be set both symmetrically and asymmetrically around 0 Hz. Voltage: Here the allowed voltage difference between UGEN and UBUSBAR is chosen. It can be set symmetrically. The HAS-111DG measures the busbar and generator voltages in order to obtain data on frequency, phase and voltage deviation. A synchronising signal is transmitted when the following conditions are fulfilled: 1. The voltage difference is within ±2 to ±12 % of the busbar voltage set on the VOLTAGE potentiometer, and 2. the frequency difference ∆f is within -1 to 0 Hz and 0 to 1 Hz of the values set on the FREQUENCY potentiometers, and 3. the phase angle difference is within -25 to -5 ° el. and 5 to 25 ° el. of the value set on the PHASE potentiometers, and 4. the ∆f allows a synchronisation pulse of min. 100 ms without exceeding the setting of the PHASE potentiometers. When the above four conditions are fulfilled, a synchronising signal is transmitted and the yellow SYNC LED is lit. The pulse length (100 ms to 3 s) depends on the other settings of the relay. Features : - Synchronisation of generator to busbar - Setting of phase angle difference - Setting of frequency and voltage diff. - LED indication of status - LED for synchronising signal - 35 mm DIN rail or base mounting Borna Niroo Karan (Bornika) is the exclusive agent of DEIF in the fields of consultation , sales and distribution of power industry products including Paralleling relay products .
