ARES-200 Series are digital micro-ohmmeters produced using advanced engineering technologies which can apply up to 200 A current. ARES-200 Series can easily measure contact resistances of circuit breakers, shunts & disconnectors by applying adjustable current from 1 A to 200 A with its easy-to-use software.
ARES-200 Series can calculate the real values of the resistors by providing penetration with the feature of the continuous current application. ARES-200 Series can measure from 0.1 μ Ω to 5 Ω. They are capable of measuring the static resistance of the contact points of the circuit breaker.
There is also an “Auto-Test” mode available on ARES-200 Series, which enables to start testing automatically just by connecting the leads of the sensor cables across the two points of the current path and makes it highly convenient when measuring an array of resistance values in a circuit breaker contact.
ARES-200 Series can measure idle circuit breakers as well as the earthed circuit breakers on both sides. The optional current clamp will 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, the test can be performed in barely 15 seconds. The 4.3-inch touch colour display shows all measurement results manifest on a single screen. With an easy-to-use, user-friendly interface, ARES-200 Series guide operators to perform tests quickly.
ARES-200 Series’ flash memory feature allows controlling, recording and storing measurement results (up to 100 Test Records). Also, the user can copy test records using a USB drive.
Operators can easily print the measurement results with the 2.25-inch built-in printer and can prepare on-field reports easily.
The data management platform (DMP software) can also be used to control ARES-200 Series remotely by a PC and the measurement results can be easily analysed and stored in the PC.
With the ARES-200 Series’ Bluetooth option, 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 Series’ temperature measurement channel, the temperature values of the measured sample can be taken and calculated according to the desired temperature value. Moreover, ARES-200 Series devices are compact and rugged with protection class IP67 (case closed), weighing only 9 kg.
Why do we measure contact transition resistance on breakers?
When high current passes over the switchyard, circuit breakers open the circuits or act as closing switches at the points where high current passes. Resistance value measured in periodic control of 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 Series can apply 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 is not affected by the resistance of the measuring cable.
