The SIL B is a Relay for Primary Distribution which is able to protect a feeder by means of current and voltage functions. It is normally used with a circuit breaker as cutting element. Monitors differences in voltage magnitudes, phase angles, and frequencies to perform synchronism checks across the circuit breaker. This function can be coordinated

The SIL-G is a relay for the protection of generators which is able to protect a generator by means of current, voltage and frequency functions. It is normally used with a circuit breaker as cutting element.

AQ M215 offers a modular motor protection and control solution for larger and more important motors requiring both current and voltage based protection functions along with complete measurements of accuracy up to class 0.2S for power and energy. Up to three optional I/O or communication cards are available for more comphrehensive monitoring and con

AQ T215 offers an integrated transformer voltage regulating and back-up protection solution. Automatic and manual voltage regulating and tap change position indications provide for accurate control of the power transfomer. Complete measurements of up to class 0.2S accuracy for power and energy are available.

AQ V211 offers a modular voltage protection solution for substations. Voltage and frequency protection with up to five optional I/O or communication cards and powerfull logic programming possibility make AQ V211 optimal for demanding load shedding or automatic transfer applications.

For HV, MV and LV Distribution Systems and for Decoupling, Load shedding and Loss of main (Islading) Protection. Loss of Mains (Islanding) occurs when part of the public utility network loses connection with the rest of the systems. If this situation is not detected, then the generator could remain connected, causing a safety hazard within network.
