Detection

Directional overcurrent detection is used to protect multi-source feeders to distinguish between

Directional overcurrent detection is used to protect multi-source feeders to distinguish between faults in different directions. The device has three-phase and neutral overcurrent detection.

It ensures 90° quadrant coordination during phase directional polarization. Therefore, regardless of whether the system is in fault-free or faulted operation.

The selected polarization voltage should be reasonably constant regardless of whether the system is operating without or with faults.

Phase-directed overcurrent

Phase-directed detection requires the determination of whether the current flow in each phase is forward or reverse, depending on the connection of the phase sources, the selected MTA angle, and the voltage and current phases.

Features

The multimeter is a microprocessor-based intelligent electronic device (IED) for measuring current, voltage, power and energy.

Fault current detection and overcurrent indication are also provided.

The current and voltage inputs are connected via transformers only (see Wiring). The modules support configurations with 3 or 4 voltage transformers and 3 or 4 current transformers.

The calculated values are scaled according to the constants programmed by the user for the current and voltage transformers. All values are updated after 200 ms.

Fault current can be measured up to 20 times the rated current.

The current input can withstand 50 times the rated current for 1 second.

The multimeter is equipped with two binary outputs, which are not supported in the RTU500 series configuration.

Applications

Analogue control outputs for sequential or closed-loop control, display instruments, measurement recorders, etc,

The analogue output board 520AOD01 can be connected to measuring and recording instruments, etc.

The board 520AOD01 has 2 output channels which can be configured for different voltage or current output ranges.

The module 520AOD01 can process the following types of signals:

– Analogue setpoint commands

– Floating-point setpoint commands

The following output ranges can be configured independently for each channel via on-board switches:

– ± 2.5 mA

– ± 2.5 mA ± 5 mA

– ± 10 mA

– ± 20 mA (4…20 mA) .20 mA)

– ± 1.25 VDC

– ± 2.5 VDC

– ± 5 V DC

– ± 10 V DC

Output formats unipolar, bipolar or real-time zero (4 … 20 mA) are configurable via software parameters. 20 mA) can be configured via software parameters.

Applications

The 520PTD01 circuit board is used for direct connection of PT100 temperature transmitters.

Up to six transmitters can be connected to the board. The measuring range is ± 200 °C.

Special features

Basic checks and calculation-intensive cyclic processing functions are already performed on the module, thus reducing the burden on the communication unit.

Relevant changes are transmitted as events via the WRB I/O bus.

The 6 differential inputs are not isolated from the RTU500 series power supply.

The 520PTD01 converts the analogue signal to 4096 steps (12 bits) and measures 100%.

The differential inputs are protected against static and dynamic overvoltage by protection circuitry. A low-pass filter suppresses non-line frequency AC interference.

Two additional channels are used for automatic zero calibration.

The line frequency is configurable in the configuration tool.

The microcontroller uses these configuration parameters to set up the A/D converter.

The microcontroller controls the A/D converter and performs all processing functions on the configured measurements within a conversion time of 80 ms (50 Hz).

In addition, the microcontroller communicates with the RTU system bus. All configuration features and processing parameters are downloaded from the CMU via the RTU system bus.

The module is connected to the RTU WRB I/O bus (wired OR bus) via adapter 520ADD01.

During initialisation and operation, the module performs a series of tests. If a fault occurs, it will be reported to the CMU.

All fault conditions affecting the functionality of the module are displayed as general fault signals with the red LED “ERR”.

Module faults are detected by the communication unit.
