M‑3311A Transformer Protection Relay
Configuration Options
The M-3311A Transformer Protection Relay may be purchased as a fully configured two, three or four winding
Transformer Protection System. The M-3311A can also be purchased with the Optional Voltage Protection
Package to expand the system to satisfy specific application needs.

Multiple Setpoint Profiles (Groups)
The relay supports four setpoint profiles. This feature allows multiple setpoint profiles to be defined for different
power system configurations. Profiles can be switched either manually using the Human-Machine Interface
(HMI), communication, or by control/status inputs.
Metering
Metering of voltage, three-phase and neutral currents, and frequency. Phase voltage and current metering
include sequence components.
Real Time Demand (interval of 15, 30 or 60 minutes), and Maximum Demand (with date and time stamp)
metering of current.
Metering accuracies are:
Voltage:
0.5 V or
0.5%, whichever is greater (range 0 to 180 Vac)
Current:
5 A rating,
0.1 A or
3%, whichever is greater (range 0 to 14 A)
1 A rating,
0.02 A or
3%, whichever is greater (range 0 to 2.8 A)
Power:
0.01 PU or
2% of VA applied, whichever is greater
Frequency:
0.1 Hz (from 57 to 63 Hz for 60 Hz models; from 47 to 53 Hz for 50 Hz models)
Volts/Hz:
1%
Oscillographic Recorder
The oscillographic recorder provides comprehensive data recording of all monitored waveforms for Windings 1,
2, 3 and 4. The total record length is user-configurable up to 24 partitions. The amount of data stored depends
on the winding configuration and number of partitions. For example; 2 windings and 1 partition configuration
can store up to 311 cycles, 3 windings and 1 partition configuration can store up to 231 cycles and 4 windings
and 1 partition configuration can store up to 183 cycles.
The sampling rate is 16 times the power system nominal frequency (50 or 60 Hz). The recorder is triggered
by a designated status input, trip output, or using serial communications. When untriggered, the recorder
continuously stores waveform data, thereby keeping the most recent data in memory. When triggered, the
recorder stores pre-trigger data, then continues to store data in memory for a user-defined, post-trigger delay
period. The records may be analyzed using Beckwith Electric IPSplot
®
Plus Oscillograph Analysis Software,
and are also available in COMTRADE file format.
