Contact Resistance Tester / Ductor Testing
 The contact resistance is the resistance to the current flow in electrical connections, due to surface conditions in the connection o contact surface, which may lead to poor or bad connection if it is too high, causing different problems in the circuit. Therefore, the contact resistance test measures the resistance of electrical connections in switching devices, breakers, relays, joints, connectors, etc, for finding bad or corroded contacts as a preventive method, or for diagnosis and problem solving.
The contact resistance test is very important for contacts that carry large amounts of current (e.g. circuit breakers, busbars, cable joints, etc) as higher contact resistance leads to higher losses, lower current carrying capacity and dangerous hot spots in the substation, so that the contact resistance test is used for detecting and preventing future problems, checking the circuit or equipment condition.

Milivolt Drop Test

Milli volt drop tester is a tester which measures the voltage drop between the two test points. In effect it is a D.C digital voltage producer which will measure the voltage drop between the test points at a constant current. Usually it has two scales for amperes 0 to 20amp and 10 to 100 amps. The ranges of the voltage are: 19.9, 199.9 and 1999 mv. 

 

Salient Features:

• Solid state DC current source from 1 A to 100 A depending on the range and model
• Accurate adjustment of current with lesser time delay
• Line and load regulation of about 0.2%.
• Compact in size.
• Light weight and portable unit.
• LED Display to display test parameters and the test result.

Contact Resistance Tester / Ductor Testing

Introduction: Contact resistance is the resistance encountered at electrical connections due to surface conditions. High contact resistance can lead to poor connections, causing issues such as increased losses, reduced current-carrying capacity, and dangerous hot spots. Contact resistance testing measures the resistance of connections in devices like switches, breakers, relays, joints, and connectors to identify and address problems such as corrosion or poor connections.

Importance:

• High Current Applications: Essential for connections that carry large amounts of current, such as circuit breakers, busbars, and cable joints. High resistance can result in overheating and inefficiency.
• Safety and Reliability: Testing helps detect potential issues early, preventing future problems and ensuring safe, efficient operation of electrical systems.

Major Applications:

1. Circuit Breakers and Isolators: Ensures reliable operation and prevents overheating.
2. Shunts and Busbars: Validates efficient power distribution and accurate current measurement.
3. Cables and Joints: Detects issues in cable connections and joints to maintain performance.
4. Metallurgical Applications: Assesses the quality of metal contacts and connections in various processes.

Testing Process:

1. Setup: Connect the tester to the points of interest.
2. Measurement: Apply a known current and measure the voltage drop to calculate resistance.
3. Analysis: Compare results to acceptable values and perform maintenance as needed.

Advantages:

• Early Detection: Identifies potential issues before they cause failures.
• Efficiency: Ensures optimal performance and reduces power losses.
• Safety: Prevents dangerous hot spots and enhances system safety.
