ARES-200 BLUE is a micro-ohmmeter produced with advanced engineering technologies which can apply up to 200 A current. With its easy-to-use software, ARES-200 BLUE can easily measure contact resistances of circuit breaker, shunt, disconnector by applying adjustable current from 1 A to 200 A. It can calculate the real values of the resistors by providing penetration by the feature of the continuous current application. ARES-200 BLUE can measure from 0.1 µ Ω to 5 Ω. The ARES-200 BLUE is capable of measuring static resistance of the contact points of a circuit breaker. ARES-200 BLUE can measure idle circuit breakers as well as the earthed circuit breakers on both sides. The optional current clamp will be able to measure the part of the current going through the ground line during the test and make the calculations considering this component. The frequently used test models can be saved as templates and the tests can be performed more rapidly and quickly. Thanks to the quick test feature of the ARES-200 BLUE user interface, the test can be performed in barely 15 seconds. The 4.3 inches touch colour display shows all measurement results manifest on a single screen. With an easy-to-use user-friendly interface, the ARES-200 BLUE guides operators to perform tests quickly. ARES-200 BLUE’s flash memory feature allows controlling, record and store measurement results (up to 100 Test Records). And also the user can copy test records by using a USB drive. Operators can easily print the measurement results with the 2.25 inches built-in printer of ARES-200 BLUE and can prepare on-field reports easily. The HighTest data management platform (DMP software) can also use to control ARES-200 BLUE remotely by a PC and the measurement results can be easily analysed and stored in the PC. With the ARES-200 BLUE’s built-in Bluetooth, tests can be started remotely via DMP software and the results can be transferred to the PC. Thus, on-field tests can be performed even by a single person. With ARES-200 BLUE’s temperature measurement channel, the temperature values of the measured sample can be taken and calculated according to the desired temperature value. ARES-200 BLUE is a compact, rugged device with IP67 protection (case closed) which weighs only 9 kg.
Why do we measure contact transition resistance at breakers?
When high current passes over the switchyard, circuit breakers open the circuits or at the points where high current passes it acts as closing switches. Resistance value that measured in periodic control of the circuit breaker should be the same as the resistance value in the closed position which is very important for system safety. High resistance values may cause local hotspots, voltage drops, fire risk, unplanned power failure, and extra energy loss in the system. Maximum accuracy measurement with the 4-wire method (kelvin method) will indicate whether the breaker contacts are properly contacted, if there is any corrosion on the contacts, or it shows if there is an effect that increases the resistance. ARES-200 BLUE can flow up to 200 A current through its current cable and measure the voltage drop on both sides of the resistance with the sense terminal. Thus the calculated resistance value displayed on ARES-200 BLUE is not affected by the resistance of the measuring cable.
