600 A Dynamic Micro-OHM Meter
The Prime 600 is a micro-ohm meter that integrates both the contact resistance and the dynamic resistance measurement (DRM) as a stand-alone unit; the dynamic resistance test, which is essential in analyzing the wear of the arcing contacts in SF6 and vacuum breakers, is a function never found before in micro-ohm meters, so that with the Prime 600 is not required to combine several types of equipment for the complete static and dynamic resistance analysis, becoming an ideal option for circuit breaker testing. The Prime 600 draws the DRM time/resistance curve that describes the resistance changes on the measured spot throughout a few milliseconds, for detecting contact anomalies and wear; the analysis of the relevant characteristics and values of this curve is an effective diagnostic way of the internal condition of the breaker contacts and reveals potential problems related to the arcing contact condition without having to open the chamber. The Prime 600 micro-ohm meter provides easy and intuitive use with a touch screen and several pre-defined test modes, reducing the testing time; at the beginning of any test, the equipment checks for proper connectivity of the system, warning of possible connection mistakes; for increased safety, the Prime 600 demagnetizes the connected load at the end of each measurement.
Contact-Less Temperature Sensor
Enables the normalization of various resistance measurements to a common temperature value. The Prime 600 will capture the temperature reading and will calculate the normalized values for each test automatically.
When ground connections are in place at both sides of the measured spot, the Prime 600 will use this clamp’s reading to suppress the derived current value from the resistance calculation for an accurate result.
Dual Ground Current Clamp
Primary Injection Test Equipment
The maintenance and substation departments traditionally have found limitations when selecting primary injection test equipment. Either the equipment is a homemade brand with low reliability, poor accuracy at a low price, or a small selection of equipment with the accuracy and quality required, but at a high price.
SMC primary injection sets are a perfect solution, as the range of products is situated between the two options previously mentioned. The primary injection equipment manufactured by SMC is a large range of products that meet the power, current, and accuracy required for this type of testing.
The Raptor System sets a new standard in the design of primary injection test equipment. Leading-edge technology and engineering have been combined to achieve small, but powerful and very portable equipment. This unit provides safer working conditions and also makes electrical maintenance more efficient and accurate, taking workability in Primary injection tests to levels never seen up till now.
The LET range of primary injection test equipment is perfectly adequate to test current transformers, busbars, circuit breakers, switchboards, complete systems such as transformersrelays, and interconnections, with adequate technology and accuracy at an economic price. The large product range enables the selection of appropriate equipment required for the application required.
Multifunctional Primary Injection Test System
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 electrical installations. The massive use of digital technology and innovative design turns the Raptor system into the most portable primary test set available, at a very attractive price.
No matter the combination of master and optional units used, the entire Raptor system is controlled as a single device from the control console attached to 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 of a single person, and its modular concept avoids the need of investing in unnecessary features or carrying equipment that you will not need.
High Current Testing
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 of 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 currency easily.
High Voltage Testing
Tests requiring a moderately high AC voltage of 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.
Raptor System Components
Raptor Current Slave
Every Raptor System needs one Master unit with the Raptor HH commander connected. This basic configuration is named Raptor C-05. It can be used stand-alone for high current testing and for most measurement applications. Add Current slaves to increase the injection power or one Voltage slave for moderate-to-high AC voltage test jobs.
The current slave increases the Master unit’s compliance voltage for heavily demanding current applications. Especially appropriate for long injection cables or for current values greater than 9600 A. Up to three slaves can be added to one Master for configurations Raptor C-15, C25, and C35 respectively. Current slaves communicate with the master unit only via the built-in infrared link.
Expands the Raptor System’s test capabilities to applications requiring up to 2000 VAC injection (power transformers, insulation tests, Step & Touch Voltage measurement, and more). Pre-defined test templates included in the Raptor’s standard repertoire. Optional accessories are available for special applications and added safety measures. The Raptor CV-05 configuration includes one Raptor C-05 system and one Raptor HV slave.

Current Regulation Equipment For Laboratory Use
The testing of MCB’s enables the detection of the deviations in the characteristics and the quality control of these devices for the companies which manufacture or sells them. Random sample testing is required for MCB manufactures and is normally carried out by Utilities when purchasing large quantities. Testing those already installed in the Industry is also required.
A complete analysis is fundamental in determining, both independently and simultaneously, the characteristic of these devices with equipment that reduces testing time and has a stabilized current injection source, required by international standards. SMC has found that many MCB tests are made with homemade testing equipment, with unstable current sources, connected in series, resulting in unreliable test results and a limited capacity in the tests which can be made.
With this situation and the experience of SMC in AC current equipment, along with the demands of the market in MCB testing, the design of this range of products, required by users in this type of devices, is a product that is flexible to test various MCB’s, with different nominal values and different tests at the same time. The stabilized current generator along with software control gives reliable results. The system not only is capable of meeting international standards but also to those standards required in each country.
