Product overview:
DC resistance of transformer is the essential item to be tested in semi-finished product, finished product delivery test, installation, handover test and preventive test by electric power department, and is effective to help find manufacturing defects such as materials selection for transformer coil, welding, looseness on connection, strand breaking, wire breaking and so on, as well as hidden dangers after operation. To satisfy the requirement for quick measurement of DC resistance of transformer, our Company has developed Three-channel, DC resistance tester aiming at connection winding. The tester can fulfill functions such as simultaneous energization on three phases, independent current sampling, voltage sampling, as well as simultaneous measurement and display of three-phase resistance value and three-phase unbalance rate, thus can significantly reduce test time for DC resistance of transformer, solve the problem of long test duration for DC resistance of each tapped winding of electric power transformer. It requires only 1/3 of the time required by traditional method.
Feature and Functions:
1. One wiring can complete the measurement of three channels
2. The instrument provides 6-gear output current selection and an automatic gear. The maximum output current is 10A
3. It is applicable to inductive test objects such as transformer, mutual inductor, reactor, generator, motor, etc., and can also be used to measure test objects such as switches, copper bars, contactors, relay contacts, metal wires, cable accessories, etc
4. With perpetual calendar, 99 groups of data storage, automatic temperature conversion and other functions, no data loss after shutdown
5. A printer can output and print test data
