PAC-E100 Over Current and Earth Relay is a microprocessor-based digital relay which is designed on the purpose of management and protection of distribution lines. It has the protection functions of PAC-E100 Over Current (OCR), Earth Over Current, Thermic Over Load, Low Current, Negative Component Over Current.
Four standard IEC current time (TC) curve (normal inverse, very inverse, extremely inverse, long-time inverse) and 7 standard ANSI current-time curve (TC) are available. Also, it includes the 3-phase currents, the component current, the second of three phases of harmonic measurement, frequency measurement and for circuit breaker control functions.
PAC-E100 can be used for motor protection. To do that; protections of low current, thermic over load negative component over current are arrived with standard relay equipment. Programmable logic is designed to reduce external cabling. There are 48 pieces of adjustable logic component. The set of input and output contacts can be done easily by programmable logic. The operation and maintenance of programmable logic and PAC-E100 can made preparedness.
- Functions of Digital type Over Current (OCR), Earth Over Current (OCGR), Thermic Over Load, Low Current, and Negative Component Over Current protection.
- Can use different number of current-time curve: 4 IEC curves, 7 ANSI curves and in addition to those 2 pieces of special convenient for inductive current-time curves.
- Reclosing Function
- Relay Internal Fault control and self-diagnosis
- Supervision of Opening Circuit
- To close out on the cold charge
- LCD screen showed the setting and measurement parameters ( 2 row x 16 column)
- Adjustable system frequency (50/60Hz)
- 4 pieces of easy adjustable outlet contacts and 4 pieces of LED warning and notification indicator on front panel.
- The opportunity to issue on-off command to the breaker form the front panel locally (password protected) or the opportunity to issue on-off remote command using SCADA.
- Relay setting software with the PC easily used : system settings, protection and logic settings, monitoring and measurement
- Contact outputs can be tested by manually tripping function
- Password protection for circuit breaker control and change the settings
- Communication interface
RS232-C ( front and back face ), RS 485C (SCADA communication)
Protocol: MODBU, DNP3.0, IEC 60870-5-103
- Measurement : 3 phase currents, component currents, thermic, frequency
- Event sign-up; 1ms time labeled 127 pieces event record
- Oscillographic record; oscillographic record of input magnitudes according to programmable condition changes ( opening signal, condition changes at input or output contacts etc.)
- The opportunity to make the breaker maintenance program with cumulative open counter
- Relay can send blocking signal to another relay or can be blocked by another relay
