Primary current injection tester

1. Application

DDL-3000BS Primary current injection test set (Transformer ratio time & large current generator)  is a test equipment developed by our company, mainly used for thermal relay, motor protector, contactor, circuit breaker, air switch, switch cabinet, protection screen calibration; It is widely used in the scientific research, production and electrical test sites of electric power, railway, petrochemical, metallurgical and mining enterprises.

It is widely used for test items such as primary bus protection and transformer turns ratio of various current transformers such as scientific research, production and electrical test sites of electric power, railway, petrochemical, metallurgical and mining enterprises.

The device is designed as a compact all-in-one.

  

2. Advantage

1) Voltage and current 6¹/₂ LCD display, with higher display accuracy and more accurate experimental results

2) 128 * 64 dot-matrix LCD display, more intuitive data display and faster reading

3) Timer 0.01S-9999.999S LCD display

4) High measurement accuracy: class 0.2

5) The instrument display locking function, especially for the transformer ratio test, which can obtain readings more accurately and quickly

6) Self-locking function

7) RS232 communication function, experimental results can be directly uploaded.

8) Polarity measurement, automatic measurement of transformer polarity, without separate experiment

9) Transformation ratio automatic detection function

10) Internal stop meter function

11) Beautiful and generous PVC panel, more resistant to dirt and durable.

12) Large power and strong load capacity.

13) Small size, light weight, only 30%~70% of the volume of similar products, very convenient to carry.
