High Precision High Voltage Switch Contact Resistance
Tester Loop Diuretic Resistance Megohm Meter
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.
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 IEC62271, 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 100A, 200A, 400A and 600A, 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.
