| | | | Prevents malfunction or non-function.
- Dual protection function: Effect of protecting a single feeder using two relays. | | Strong noise resistance
- Shielding of electromagnetic waves - Passed both EMC and EMI tests - Dual filter adopted to remove measurement noise | | Allows for easy identification of health of CT and PT
- Alarm sound upon breakage or mal-wring of CT or PT: use of 4CT and GPT wiring | | | | Used to measure k-Factor and harmonics.
- Measurement of harmonics: Measure the second to fifteenth harmonics.
Check the waveform distortion and Sag/Swell using an oscilloscope function. | |
| | | | | Applicable to BAS (Building Automation System).
- Support of BAS protocol: LonWorks, BACnet (Option) | | Support of standard protocols - Modbus, DNP3.0
- No need for a additional protocol converter | | | | Use of 10/100Mbps Ethernet to support high-speed communication.
Redundant communication channels can be used in parallel.
- Communication is available even when one channel fails. | | | | Support of various language (Korean, English, Chinese)
- Enables swift reaction upon emergency, and prevents mal-operation
Built-in alarm generation function
- No need for additional alarming device
Trip logic can be configured as a user desires
A sequence such as the inter-lock between a relays or switchgears can be implemented. | | | | | | Item | ProPAC II - FD | ProPAC II - MT | ProPAC II - TR | | | Relay Elements | | Under voltage (UVR 27) | Over-current (OCR 50/51-1) | Under voltage (UVR 27) | Under current (UCR 37) | Over-current (OCR 50/51-2) | Negative sequence over- current (NSOCR 46) | Negative sequence over- current (NSOCR 46) | Over-current ground (OCGR 50/51G-1) | Negative sequence over- voltage(NSOVR 47) | Negative sequence over- voltage(NSOVR 47) | Over-current ground (OCGR 50/51G-2) | Over-current (OCR 50/51) | Phase open relay (POR 47P) | Selective ground (SGR 67G-1) | Over-current ground (OCGR 50/51G) | Stall/Lock (48/51LR) | Selective ground (SGR 67G-2) | Over-voltage (OVR 59) | Thermal Relay (THR 49) | Directional ground (DGR 67N-1) | Over-voltage ground (OVGR 64) | Over-current (OCR 50/51) | Directional ground (DGR 67N-2) | Selective ground(SGR 67G) | Over-current ground (OCGR 50/51G) | Percentage differential (PDFR 87T) | Directional ground (DGR 67N) | Selective ground(SGR 67G) | Instantaneous differential (IDFR 87) | Phase open relay(POR 47P) | Directional ground(DGR 67N) | Over-voltage ground (OVGR 64) | | Notching relay (NCHR 66) | Inrush Detector (68) | | Display | Measu rement Items | Current, voltage, frequency, power factor, vector diagram, active power/energy, reactive power/energy, apparent power/energy, harmonics (voltage/current), Spectrum, waveform (voltage/current), zero phase voltage and current, 3-phase vector diagram, K-Factor, Voltage unbalanced factor, voltage(max, min, average) | | Display Unit | Graphic LCD(320 x 240) | | Input/ Output | Digital Input | Input 16 points | Input 16 points | Input 16 points | | Digital Output | Output 16 points | Output 16 points | Output 16 points | | Analog Input | CT : 5 pts.
