The risk of overheating is becoming more serious due to the fact that today's distribution networks have to carry heavier loads. Checking contact resistances at regular intervals detects faults before they cause overheating. Bad contacts are the cause of failure or poor performance in a wide variety of electrical devices, while sufficiently high contact resistance can cause substantial heating in a high current device. Unpredictable or noisy contacts are a major cause of the failure of electrical equipment.
DESCRIPTIONT-216 600A contact resistance tester are used to measure contact resistances in high voltage breakers, disconnecting switches (isolators), knife-contact fuses, bus joints, line joints etc. It adopts the top open structure or vehicle mounted horizontal chassis.
It has that vantage: more small volume, more light weight, more strong functions, and the simple operation. It designed for field tester design. The high output voltage is 10V. Display is 160*128 large LCD screen. Test current optionally, test time can be set, test process dynamic tips, suitable for different working environment.
The GFUVE T-216 is a 600 A micro-ohmmeter that measures resistances between 0.1 μΩ and 20mΩ at high currents. This functional instrument can provide test currents from 100 amps up to 600 amps DC subject to the load resistance and supply voltage and uses a four-terminal measurement technique to cancel the resistance of the test leads from the measurement.
