First Test System of “Kalibr” Product Range!
Application
RETOM-71 is designed for test and high-accuracy metrological verification of:
- relay protection and automation electromechanical devices,
- protections with up to 6 voltage sensors (with voltage source supervision, fuse failure blocking),
- digital devices with IEC 61850 support,
- high-accuracy automation and control devices,
- electric power meters,
Main advantages:
- accuracy class of 0.1% enables high-accuracy metrological verification of both relay protection and automation devices, electric power meters, etc.;
- 6 current sources are designed for fully functional test of any relay protection and automation devices, including differential protections. Max. output current in six-phase mode is 20 A, in three-phase mode – 40 A, in single-phase mode – 120 A;
- 6 voltage sources enable test of protections with a high number (up to 6) of voltage channels. Max. output value of each phase is 140 V;
- 16 binary inputs and 16 binary outputs enable fullest possible analysis of response of complex relay protection and automation devices. New convenient connectors significantly simplify connection and configuration diagrams;
- compact nature – the device, with its small weight (16 kg) and dimensions, provides output parameters required for test of both electromechanical and all types of modern protections;
- support of IEC 61850 standard – 2 embedded Ethernet-ports enable interference-immune connection with the controlling computer, as well as receiving and issuing of GOOSE-messages (16 incoming messages/16 outgoing messages);
- a wide range of standard software programs enables test of any protections in manual and semi-automatic modes;
- “Sequence Generator”, “RPA Test”, “RETOM-Master”, “Test Generator” programs, included in the delivery set, enable developing individual test scripts;
- a wide range of accessories, included in the delivery set, contains different cables and adapters for fully functional tests of RPA systems of any complexity;
- more than 65 special programs for automated tests of RPA devices of well-known manufacturers can be additionally included in the delivery set at customer’s request;
- high interference immunity – the system meets requirements of GOST R 51317.6.5-2006 (IEC 61000-6-5:2001) and FGC UES Company Standard 56947007-29.240.044-2010, which enables its use at substations of any voltage level;
- guaranteed reliability – new design and circuitry solutions ensure system high reliability both in operation and transportation;
- verification interval of 4 years.
