Phase meter E1600 (E-1600, E 1600, E1600, e1600, e-1600, e 1600) analogue E160 (E-160, E 160, E160, e160, e-160, e 160)
For the power factor measurements in three phase, 50 Hz, 60 Hz and 400 Hz at even load phase and symmetrical voltage.
Accuracy class 2.5.
Phase meter E1600 rednaznachen for measuring power factor in three phase, 50 Hz, 60 Hz and 400 Hz at even load phase and symmetrical voltage.
Connecting the E1600 series circuit device (E160) via current transformers with a secondary winding on the 5A or 1A, or through current transformers with a secondary winding on the 5A. or through intermediate current transformers I1820 with ratio 5/1. Measurement range capacitive cosφ 0 - 1 - 0 ind. The device parameters F azometry E1600 are shown in Table. 1.
Response time is less than 3 seconds. Changing E1600 phase meter readings caused by ambient temperature deviation from normal for every 10 K, corresponding to 0.2 Acceptable basic error. Admissible additional error of the instrument under the influence of an external magnetic field induction 0.5mTl frequency equal to the frequency of the current flowing through the measuring circuits, does not exceed 0,4 admitted basic error.
Power consumed by each successive chain unit E1600, at rated current and frequency of 50 Hz and 60 Hz is less than 5 W at a frequency of 400 Hz - 10W. Power consumed by the parallel circuit device at rated voltage and frequency of 50Hz, 60Hz and 400Hz is less than 8W.
Electromagnetic system of the device with a moving part on cores, the dial. Weight 2.3 kg. Time to failure of at least 33300ch. In terms of resistance to climatic influences device complies with GOST.
