Fanox increase the range of its catalogue for primary distribution protection relays including Brand new SIL – G model which is able to protect a generator by means of current, voltage and frequency functions. It is normally used in Cogeneration in power stations from gas, steam, hydraulic turbine, or diesel driven generators
SIL G monitors variations in voltage magnitudes, phase angles, and frequencies to perform synchronism checks across the circuit breaker. These functions can be coordinated with the auto-reclose function (up to five recloses). It is powered with auxiliary power supply (110-230 Vac/ 90-300 Vdc and optionally 24-48 Vdc), and following protection functions are available: 81R, 78, 81 U/O, 27P, 32/40, 59P, 59N, 25, 79, 50P, 50N/G, 67P, 67N, 46, 79, 50BF, 52, 49, 86,CLP, 49T, 74TCS, 37 and IRIG-B.
Other remarkable added values for SIL-G are the metallic box with high electromagnetic compatibility level (EMC) and wide range of operating temperature. Its reduced size makes the SIL-G relay easy to install and its light weight helps the customer to save costs in transport.
