Selectable AC transducer

TAS-311DG is a micro-controller based AC transducer with 1 analogue output for measurement of RMS voltages, RMS current, phase angle or frequency on an AC-network. TAS-311DG can be delivered pre-configured or it can be delivered unconfigured for customer configuration through the PC interface. The PC configuration software allows free choice of voltage, current, phase angle or frequency measurement including configuration of the measuring range and output range without any mechanical settings or adjustments inside the transducer. The transducer holds no mechanical moving parts like potentiometers, and the calibration stability is excellent.

Selectable AC transducer

TAS-321DG is a micro-controller based AC transducer with 1 analogue output for measurement of bi-directional current. The sign for current direction is based on the measured power direction. Furthermore, the transducer can be used for measurement of active power or reactive power on a 3-phase network where only 2 phases are available for the measurement. TAS-321DG can be delivered pre-configured or it can be delivered un-configured for customer configuration through the PC interface.

Multi differential protection relay

The MDR-2 differential protection relay is a micro processor based control unit containing all necessary functions for monitoring of the differential currents for a synchronous/asynchronous generator or motor (the object). Via current transformers the MDR-2 measures each phase current on both sides of the object. The current transformers determine the limits of the protection area. Any failure within these limits (2- or 3-phase short circuits or earth leaks) will be detected as an error Id: Differential currents, the currents flowing through the two current transformers of the phase in question differ, and, if a preset limit value is exceeded, a warning will be given or a tripping signal transmitted. The MDR-2 dynamic compensation curves for warning and tripping are defined by the user.

Frequency relay

The digital, combined under-frequency and over-frequency relay type RMF-112D forms part of a complete DEIF series of relays for protection and control of generators. The relay is type-approved by major classification societies and is applicable to both marine and land-based installations. The RMF-112D is applied for protection against under-frequency and over-frequency by supervising the frequency (of generators) in single phase and 3-phase networks.
