P126 & P127 can indicate the phase(s) in fault by configuring output relays (first stage only). Directional / non Directional Overcurrent ProtectionThe MiCOM P12x/y relays have separate instantaneous and delayed information for each stage. Available in a self-powered or in a dual-powered. They can be applied to a wide variety of high and medium voltage electrical systems as either main or backup protection. MiCOM P124 are numerical relays designed to offer complete overcurrent protection without requiring any external auxiliary supply. Detail RELAY MICOM P122, P124, P127 AREVA.The P12x relays can be used for a range of overcurrent applications from single phase/earth fault applications, P120 (non directional), P125 (directional) to three phase and earth fault applications, P123 (non directional), P127 (directional). Please send your request specifications Perumahan, Malaka Country The MiCOM P12x relays are suitable for all the applications where overcurrent and earth-fault protection are required. HIGH IMPEDANCE THREE-PHASE DIFFERENTIAL PROTECTION (87) The phase inputs of MiCOM P12x relays can be applied in the typical high-impedance scheme forThis document does not replace the Technical Manual.Jual MiCOM RELAY P120, P121, P122, P123, P125, P126, P127, P132, P142, etc Schneider Murah Jakarta We are a company engaged in the General Contractor, Electrical, Panel Maker. P122 micom relay manual P122 Micom Relay Manual.MiCOM P122, P123, P126 & P127 relays provide a definite time undercurrent protection.This function allows typical applications such as loss of load or simple broken conductor detection.1A and 5A dual rated CT inputs are available with all MiCOM P12x relays using separate terminals. Three earth fault sensitivity current inputs are available by ordering code. Flexible automation functions enable accurate coordination with other devices. The typical applications are overhead lines, underground cables and backup for HV systems in insulated, solid, resistance and Petersen coil earthed neutral systems, used in MV utility, Industry, transports, Generator and transformer schemes.For easy adaptation to varying system operating conditions two independent setting groups are provided. The P12x relays provide a comprehensive suite of overcurrent protection and automation features for easy adaptation different operating conditions.
![]() ![]() Areva Micom P127 Series Relays HaveThe relays can transmit to the local monitoring system (e.g. (Courier & DNP3 are not available for the P125 P126 and P127 relays). Communication RS485 All P12x series relays have a rear RS485 communications port for use with MODBUS, IEC 63, Courier and DNP3 protocols. Keypad A seven-button tactile keypad on the front panel allows the user easy access to any data.Self-Monitoring Comprehensive self-monitoring procedures within the devices ensure that internal hardware or software errors are detected and do not cause malfunctions of the device. Password Protection A four-character password is requested in order to prevent inadvertent or unauthorized changing of settings or triggering of control functions. It allows the user to download new firmware (update, language changing.) and is also the link with the setting software MiCOM S1 (P122, P123, P125, P126 & P127).The simple and powerful software interface allows the user easy configuration and access to all measurements and stored information for maintenance and post-fault analysis purposes. Communication RS232 An RS232 front port is available in the MiCOM P12x series. All the parameters for the communications (relay address, data rate, parity, etc.) can be set using the front panel user interface. Areva Micom P127 Full Suite OfThe relays of these ranges comprise a full suite of protection functions as well as an automatic recloser and auxiliary functions each function can be individually configured or disabled suiting any particular application.Rear port RS485 port. The result of the fault diagnosis determines whether a blocking of the protection and control unit will occur or whether a warning only is issued.Trip Led Alarm Led Device fail Power supply Freely Programmable LedsThe main functions are autonomous functions and can be individually configured or disabled to suit a particular application. If test results deviate from the default value then the corresponding signal is entered into the non-volatile monitoring signal memory. Cyclic self-monitoring tests are running during operation. The first and second stage can be independently select as definite time delay or inverse time delay with different types of curve (IEC, IEEE/ANSI, RI, RECT), except for P120 and P121 where the second stage can only be set as definite time. See Functions Overview)Three-phase Overcurrent Protection (50/51) Earth Fault Overcurrent Protection (50N/51N) Three independent stages are available for phase and earth fault protection. Recording 5 records of 3 sec.(Description of ANSI code nos. Dekat di hati chordThe range of earth fault current sensitivity can be selected by ordering code.Three-phase Directional Overcurrent (67) Each of the three-phase overcurrent stages of the P127 can be independently configured as directional protection with specific relay characteristic angle (RCA) settings and boundaries. P126 & P127 can indicate the faulted phase(s) by configuring output relays (first stage only). The MiCOM P12x relays have separate instantaneous (start) and delayed (trip) outputs for each stage. In the P125, P126, P127 the 2nd and 3rd threshold pick-up can suspend the 1st threshold output to control selectivity. The IDMT stages have definite or inverse time reset capability reducing clearance times when intermittent faults happen. Each stage and related time delay can be programmed to provide maximum selectivity. Relative frequency chart makerThe 2nd and 3rd threshold pick-up can suspend the 1st threshold output to control selectivity The phase fault directional elements are internally polarised by quadrature phase-phase voltages. The third stage can be configured with definite time delay only.
