SMRT33 Megger Relay Test System
■For size and low weight, the SMRT33 is conceivably the smallest, lightest, highest output powered; complete three phase relay test system in the world today. The SMRT33 provides high power in both the voltage and current channels to test virtually all types of protective relays used in heavy industrial, distributed generation and low- to medium-voltage distribution substations. The SMRT33 has the smart combination of high compliance voltage and high current to test all electromechanical, solid-state and microprocessor-based overcurrent relays, including high impedance directional ground overcurrent. Inaddition, the unit includes capability to test IEC 61850 devices.
■The SMRT33 test system has the ability to be manually controlled with Megger's new Smart Touch View Interface™ (STVI). The STVI, with its large, full color, high resolution, TFT LCD touch screen, allows the user to perform manual, steady-state and dynamic testing quickly and easily using the manual test screen, as well as using built-in preset test routines for the most popular relays (see STVI datasheet for details.)
■The STVI eliminates the need for a computer when testing virtually all types of relays Menu screens and touch screen function buttons are provided to quickly and easily select the desired test function.
■Tests results can be saved to the STVI for download to a memory stick to transfer or print test reports.
For full automatic testing, the SMRT33 may be controlled by Megger Advanced Visual Test Software (AVTS). AVTS is a Microsoft® Windows®XP®/Vista™/7/8 compatible software program designed to manage all aspects of protective relay testing using the new Megger SMRT33, (see AVTS datasheet for details.)
●FEATURES AND BENEFITS
■Constant Power Output: New higher powered voltage-current amplifiers. The current amplifier delivers maximum compliance voltage to the load constantly during the test, and range changing is done automatically under load. This insures better test results, and saves time by not having to turn the outputs off to change ranges. Constant power output in many cases eliminates the need to parallel or series current channels together to test high burden relays.
■High Output Current: Provides up 30 amps at 200 VA per phase continuous. The three current amplifiers can be paralleled to provide a maximum of 135 amperes at 900 VAZ for testing instantaneous overcurrent relays.
■New PowerV™ Voltage Amplifier High Power Output: The SMRT33 provides a new higher VA power output on the voltage channel at the lower critical test voltages (from 30 to 150 volts). Customers who want to test a panel of relays at one time find it impossible using lower VA rated voltage amplifiers.
■Steady-State and Dynamic testing capability:The SMRT33 provides, either through manual control or computer control, both steady-state and dynamic testing of protective relays. This includes programmable waveforms with DC offset and harmonics.
■Output current and voltage sine waves are generated digitally: Outputs do not vary with sudden changes in input voltage or frequency, which increases test accuracy and reduces testing time.
■Digital binary inputs and outputs: The programmable binary inputs, and programmable outputs provide timing and logic operations in real-time with the output voltage and currents. Binary Inputs can be programmed, using Boolean logic, for more complex power system simulations. This provides a low cost, closed loop power system simulator.
■Circuit breaker simulator: Binary outputs provide programmable normally closed and normally open contacts to simulate circuit breaker operation for testing reclosing relays. Sequence of operation, timing, and lockout are easily tested.
■Performs transient tests: Perform acceptance or troubleshooting tests by replaying digitally recorded faults or EMTP/ATP simulations in the IEEE- C37.111, COMTRADE standard format.
■Perform End-to-End tests: Using AVTS or RTMS software and a portable GPS satellite receiver, the SMRT performs satellite-synchronized end-to-end dynamic multi-state (AVTS or RTMS) or playback transient COMTRADE files (AVTS) either for commissioning or troubleshooting tests.
■Wide-ranging output frequency: The output frequency of the current and voltage channels can be set for any frequency from de to 1 kHz Multi-purpose test system saves time and money
■Three Ethernet ports: PC/OUT Ethernet port is the primary PC connection port, or used to interconnect multiple SMRT units together for synchronous multi-unit operation. The IN/61850 Ether net port is used to in terconnect multiple SMRT units together for synchronous multi-unit operation or to connect to the IEC 61850 substation bus. The STVI PoE (power over Ethernet) port and is used to connect to the STVI.
■Bluetooth: Optional Bluetooth provides more flexibility. A wireless interface between the PC and SMRT, in conjunction with the SMRT IEC 61850 Ether net port, provides the isolatio n required for a secure substati on access in terface between the SMRT and the IEC 61850 substation network.
■Open communication architecture: Use with third party software for more flexible automated control.
Immediate error indication: Audible and visual alarms indicate when amplitude or waveforms of the outputs are in error.
■Optional Transducer Testing Capability - This optional hardware feature (see Ordering Information) provides transducer DC In puts to test transducers easily and effectively. The STVI software is designed to automatically recognize the Transducer DC Inputs, and thus provide the Transducer lest Screen when selected. AVTS software comes standard with Transducer Test Modules, which will provide automatic transducer test capability in conjunction with the optional hardware.
