Contact Resistance Tester
-
Weshine Electric Manufacturing Co., Ltd
The loop resistance tester is used to test the conductive loop resistance of various switchgear, and the test current shall not be less than 100A. Due to the oxidation of the contact surface, poor contact tightening and other reasons, the contact resistance increases. When a large current flows, the temperature of the contact point increases, which further accelerates the oxidation of the contact surface and further increases the contact resistance.

Earth Contact Resistance Tester
-
SCR ELEKTRONIKS have developed an equipment namely Earth Contact Resistance Tester to test the appliance. To ensure the safety of operator it is essential that the Earth path (connection) should offer minimum impedance to by pass short circuit Current to Earth. This is ensured by measuring Resistance of the Earth path by passing heavy Current say 25 A. The Earth Contact Resistance Tester essentially comprises of a Variable Current source with digital Ammeter to measure the Current supplied. The Voltage drop across the Earth path is measured with a digital Voltmeter. Optionally for a particular Current (25 A) the meter can be calibrated in terms of Resistance. A timer is provided to switch off the Current after the Set Time.

Contact Resistance Tester
JYL
-
As a high current passes through a pair of mechanically independent metallic contacts, the contact resistance must be as low as possible. Increasing the contact resistance of the contact often causes a large voltage drop on the contact, which reduces the input power of the load equipment. If the contact resistance of one or two contacts becomes large, the three-phase voltage of the load equipment will be unbalanced, causing phase loss operation.

Micro-Ohmmeters
RMO-G Series
-
The RMO-G is a portable micro-ohmmeter designed for contact resistance measurement of non-inductive test objects and applications with increased safety requirement. It tests medium and high-voltage circuit breakers, disconnecting switches, high-current bus bar joints, cable splices, and different high-current links. Due to its Both Sides Grounded and Remote Control functionalities, the instrument accurately measures even in the most demanding environments, providing additional safety to testing personnel.The RMO800G is the most powerful portable micro-ohmmeter on the market with 800 A output current. RMO200G is our best seller in the USA. A user can choose the appropriate model depending on the output current requirement, from 100 A (RMO100G) to 800 A (RMO800G).We use an unbreakable plastic case with IP67 protective rating (with closed lid) for instruments’ housing. Although very portable and lightweight, RMO-G micro-ohmmeters have very high output power capabilities. High output voltage enables a wider measurement range at higher test currents. Consequently, it enables the usage of thinner/longer test cables. RMO-G generates a true DC ripple-free (less than 1 % ripple) current with automatically regulated test ramps. During the testing, it increases current before measuring and decreases current after the measurement. This significantly decreases magnetic transients and ensures great accuracy.Special current clamps measure a current through groundings when the instrument tests in Both Sides Grounded conditions. The instrument itself powers these clamps. If even higher safety level is required, the Remote Control feature enables the operator to perform measurements from distant locations.RMO-G instruments can store up to 500 measurements in internal memory. Also, they have a built-in thermal printer and USB flash drive available as an option. An additional option is the built-in High Precision module suitable for measurement of very low resistance, in the range from 1 to 30 µΩ, with 0,01 µΩ resolution.Our free DV Win software communicates with the RMO-G micro-ohmmeters via USB or RS232 interface. It allows a user to run the test remotely from a PC. Also, a user can download test results, analyze and generate fully configurable test reports through the software.
