The unit is extremely compact and rugged. The design incorporates the latest in modern digital microprocessor technology to achieve unbeatable output characteristics in terms of power, accuracy, low distortion, and dynamic capability. This technology allows users to test many different specific functions required in relay testing, without the need of additional accessories. All output signals are digitally generated, amplified, and internally controlled by the IGM’s (Intelligent Generator Modules), which interpret the orders received from the front panel to produce a highly accurate, stable, and low distorted output, independent of the voltage supply.
The equipment also allows optional connection to a computer for either automatic testing of relays or control of the equipment using Windows compatible software. Even the adjustment and calibration of the equipment is made by software, supplied with the units, which permits calibration and/or adjustments in the outputs, without any manual hardware setting.

MONITOR 12

The proper operation of the protective relays is critical in the reliability and safety of power systems, protecting other devices from damage and helping to the system security. Accordingly, the testing of relays is required during the installation and commissioning process, and as part of the maintenance programs throughout its service life.

Relays testing may range from a simple check of some points of the relay characteristic to a complete verification of the protection scheme logic, even including the response to transient waveforms, harmonics, etc.
Since the manufacturing of secondary injection equipment for testing protective relays has been a main activity of SMC, we are able to offer different comprehensive solutions with all the required characteristics and functions needed to ensure the proper operation of relays, in a manual or automatic testing mode; solutions which are designed for maximum efficiency, flexibility and simplicity, with the required accuracy and performance to test any kind and type of relays in all situations.

The ease of use and the testing speed are always considered in the SMC equipment, for adapting the relays testing to the user and the application. The test equipment should also deal with some practical questions required in the different situations that the user may face for the proper testing of protective relays, which might sometimes require an easy and simple human interface with quick and full manual control and other times, when required, testing the relays in automatic way.

Our experience obtained during the past 30 years has enabled us to have a complete range of equipment with different philosophies for the various applications and customers, from the simplest and autonomous sets to fully automated, for quickly performing any type of relay testing.

This revolutionary product, the most modern equipment of its class, fulfills the requirements of the transmission departments and the commissioning of new installations; the unique which is PC independent, with easy and intuitive touch-screen, modular concept up to 12 channels, advanced built-in test tools, independent amplifiers and lower maintenance. The MENTOR is perfectly suited for secondary injection tests, with a big sized screen that allows continuous graphic and visual monitoring of the test process, and the quickest and most complete manual control. The MENTOR integrates many useful functions for the proper testing of protective relays without the need of external PC, such as State Sequencer, Fault, Ramping, Pulse Ramps, Binary Search, COMTRADE playback, and on screen direct regulation of complex magnitudes (impedance, power, symmetrical components, homopolar voltage, etc).

The modularity of the Mentor allows multiple configurations, from the classic 3V3I (3 Voltages- 3 Currents – with 6 currents available), 4V3I, 4V6I, etc, up to the maximum of 6V6I (two 3-phase systems in one unit, 6 Voltages – 6/12 Currents) with plug-and-play amplifiers modules which can upgrade the system at any time when required for some specific types of relays or schemes, and are also interchangeable between units.
For other products that are also related to relay testing, please also check the following product categories: Electrical Measurement Equipment, Monitoring, Testing Accessories and Testing Software.

Raptor primary test system

The simplest Raptor configuration gathers a comprehensive set of resources and test functions in an ultra compact, remarkably portable 77-lb (35 kg) body: master unit, detachable touch-screen console, voltage and current measurement inputs, dual voltage / current test source, binary input, and a 3-kVA digital amplifier for a maximum 9,500 A current injection with variable frequency.
A large diversity of test jobs can be accomplished, including circuit breaker and re-closer testing, ground grid integrity verification, transformer saturation analysis, burden and ratio measurement, and more.

For high current applications, the Raptor implements the ‘pass-through secondary’ technique, with a centered hole that confers to this product a unique personality.
You only need to drive the current conductor through the Raptor and attach both ends to the device under test. Multiple cables can be used in parallel to increase the effective cross section, and the compliance voltage can be easily multiplied by just doing multiple turns around the unit. If additional power is required,5-kVA slave units can be added for up to a total 18 kVA and a maximum 15,000 A injection.

These units communicate with the master Raptor via an infrared link, so no physical interconnections are required. An integrated software calculator allows determining the equipment and cabling required to attain a specific amount of current easily.

Tests requiring a moderately high AC voltage up to 2,000 V can be accomplished by adding the Raptor HV to the system. These jobs include power transformer evaluation, voltage withstand / isolation tests, and step & touch voltage measurement, among others.

The Raptor HV is visually similar to the other Raptor units but lacks the characteristic center hole in the current injection models.
No matter the combination of master and optional units used, the entire Raptor system is controlled as a single device from the control console in the master unit. This small command center features a magnetic rear face and implements a comprehensive collection of pre-configured tests that can be customized and extended by the user. Custom settings and test results are permanently stored for subsequent download from a PC via a standard USB port. The Raptor console can be directly updated over the Internet via its built-in RJ-45 Ethernet® LAN connection.

The Raptor is a stabilized injection system, i.e. it will compensate small supply and load variations automatically to guarantee the test values throughout the entire job’s duration. Its compact and robust design enables the use by a single person, and its modular concept avoids the need of investing in unnecessary features or carrying equipment that you will not need.

The Raptor system consists of a main ‘master’ unit and a number of optional units that enable the execution of virtually any commissioning or routine testing jobs on the primary equipment of medium and high voltage electricity installations.
