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 Measurement System
CRMS
-
The CRMS is a system designed to allow any user to measure the resistance of each set of relay contacts associated with the relay under test. The test system consists of a CONTACT RESISTANCE MEASUREMENT UNIT (CRMU), a MULTIPLE RELAY TEST RACK, as well as an interconnect CABLE ASSEMBLY. Either DC or AC energy to pick and drop relay coils under test for all contact measurements is supplied from the CRMU and easily interfaces with the Multiple Relay Test Rack. For additional and more thorough testing of relays an external relay tester can be interfaced to the Multiple Relay Test Rack to supply energy to the relay coil. It is recommended that the UTE Relay Tester With Timer/Counter (UTE Product # 15967-00) be utilized so the operator can take full advantage of the unique features it offers

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.
