What is Contact Resistance?

**-High Precision High Voltage Switch Contact Resistance Tester Loop Diuretic Resistance Megohm Meter

Contact resistance is the resistance to current flow, due to surface conditions and other causes, when contacts are touching one another (in the closed condition of the device). This can occur between contacts of:

· Breakers

· Cont actors

· Relays

· Switches

· Connectors

· Other switching devices

What is Done During Contact Resistance Testing?

**-High Precision High Voltage Switch Contact Resistance Tester Loop Diuretic Resistance Megohm Meter

The two common checks conducted on the contacts of a circuit breaker are the visual inspection check and the contact resistance check.

1.The Visual inspection check involves examining the contacts of the circuit breaker for any pitting marks due to arcing and worn or deformed contacts.
2.The second check is the contact resistance measurement. This involves injecting a fixed current, usually around **0A, **0A and **0 A through the contacts and measuring the voltage drop across it.This test is done with a special contact resistance measuring instrument. Then, using Ohms law, the resistance value is calculated. The resistance value needs to be compared with the value given by the manufacturer. The value should also be compared with previous records.

Both these tests need to be done together. As there are cases of contacts having good contact resistance yet being in a damaged conditions. Thus, for a contact to be certified healthy, it needs to have a good contact resistance and should clear the visual inspection test.

Product Description

**-High Precision High Voltage Switch Contact Resistance Tester Loop Diuretic Resistance Megohm Meter

l Intelligent loop/contact resistance tester is based on the new power standard IEC****1, the use of high frequency switching power supply technology and digital circuit technology combined design.

l It is suitable for the measurement of circuit resistance of switching control equipment.

l The circuit resistance can be directly measured at the current of **0A, **0A, **0A and **0A, and the final test results are displayed digitally.

l The instrument is accurate in measurement and stable in performance, and meets the requirements of on-site maintenance of high-voltage switches in power and power supply departments and circuit resistance test in high-voltage switchgear factories.
