Primary Current Injection Fast delivery I 24-hour customer service I customizable Product Introduction HZ5371L Primary Current Injection Tester (referred to as the current riser), Mainly used for thermal relay, motor protector, contactor, breaker, air switch, switch cabinet, circuit breaker, protective screen calibration; Used for primary bus protection and various current transformer ratio test projects, is widely used in electric power, railway, petrochemical, metallurgy and mining enterprises scientific research, production and electrical test site. (1) Name: HZ5371L Primary Current Injection Tester. (2) Environmental group: Group III instruments in GB6587.1-86 "General Outline of Environmental Test for Electronic Measuring Instruments" (can be used in outdoor environment). (4) Output single-phase 0-1000A AC current; The current can be smoothly and continuously adjustable, the accuracy is higher than 0.1 level; The output current is the standard sine wave, the burr is small, better than the power system requirements indicator standard, ripple system The number is less than 0.3%. (5) Output current mode: the true RMS value is continuously adjustable; (6) Output waveform: standard sine wave; ♦ Can synchronize the operation time of the test equipment ♦ Automatic identification of normally open and normally closed contacts ♦ Several checks can be connected in series at the same time to improve work efficiency ♦ Direct display of primary current, secondary current test value, easy to observe and record the test. ♦6 and a half display, the country's first 6 and a half display, the display accuracy is higher, the experimental results are more accurate ♦ Large screen LCD display, display data more intuitive, faster reading ♦ Instrument display locking function, especially for the transformer change than the test can be more accurate and faster degree
