The RTP 300™ is a compact size digital integrated protection
relay, suited to protection relay and power measurements in
the field. The RTP 300 measures both fundamental component
of ±1.0% class for protection relay and true RMS of
±0.3% class for general measuring.
The RTP 300 provides high accuracy measurements of voltages,
currents, power, energy, power factor, frequency, demand,
maximum/minimum, and power quality, such as THD, harmonic
analysis, and vector diagram in power system.
Data monitoring and function setup are made easily both by
graphic LCD and key navigation on the front panel of the device.
The RTP 300 has the space-effective dimension[240 x 310 x
148mm] which is on world best level.
The RTP 300 has a RS485 port on the back side. PowerDX™ software
allows you to monitor and setup the device on communication
network.

Protection
|
|
The RTP 300 provides the protection both of general feeder
and motor, and directional power relay[32P, 32Q] required
for combined-heat power plant and distributed power system.
And protection components[OCR, OCGR, OVR, UVR, OVGR and etc.]
can be registered with two characteristic curves.
|
|
|
|
Total Metering
|
|
The RTP 300 provides measurements of both of fundamental
component[full scale ±1.0% class]for protection relay,
and high accuracy true RMS[full scale ±0.3% class]for
general measuring. And the positive/negative components of
voltage and current, average, maximum/minimum, and demand
measurements are provided.
|
|
|
|
Control
|
|
The RTP 300 has 11 digital input channels, 6 digital output
channels, and separately input/output channels for the control
of CB. The digital input channel performs sequential functions
according to the conditions preset to the channel, and the
digital output channel supports three modes, such as pulse,
self-resetting, and latch to conform to a variety of sequential
requirements.
|
|
|
|
Online Monitoring/Control
|
|
The RTP 300 has a RS485 port and supports Modbus RTU protocol.
Users easily build online power monitoring system by PowerDX
software or any other automation programs.
|
|
|
|
Power Quality
|
|
The electrical energy data from the meters offers the information
for management and analysis of energy usage, adapted to operate
or plan the power facilities of energy suppliers and consumers
recently or in the near future. Particularly demand measurements
can be used as principal data to reduce energy cost.
