NAYJFH PT secondary load on - line testing device
Opis izdelka
Main Features
⑴ to achieve three-phase three-wire, three-phase four-wire, single-phase automatic measurement;
⑵ use of engineering plastic chassis, get to know durable, effective protection of test personnel and system security;
⑶ instrument has a range of automatic switching function to ensure that the test accuracy;
⑷ the use of electronic principles of the line with DSP technology is to make the test stability, anti-interference ability;
⑸ measurement is completed, the automatic calculation and load-related parameters, to facilitate customer analysis and testing.
⑹ using large-screen LCD display in English, all operations by the Chinese and English menu prompts; data with power-down storage and browsing capabilities, can send data with the computer on-line.
⑺ 7.2V11Ah lithium battery with high-capacity power supply, the test circuit does not have any effect, to avoid the system appears to protect the situation. While in the field without power supply in the case of use.
⑻ second load test, using clamp-type ammeter sampling current, do not disconnect the secondary circuit. Can achieve non-blackout on-line measurement. Automatic switching range: the measurement process can be different according to the test object to switch to a different location, so that measurement accuracy and display digits are guaranteed.
⑼ working hours can be up to 24 hours (the longest).
⑽ with a lightweight charger to facilitate measurement, in the case of battery power can be an external charger measurements.
⑾ equipment, small size, light weight.
⑿ wide secondary operating current / voltage range. In the 50mA operating current, can distinguish 1mΩ resistance and reactance, can test the secondary rated current of 5A S-class current transformer on-line actual load; 5V operating voltage, can distinguish between 0.001mS conductance and susceptance .
⒀ can store 480 sets of measurement data, power can be maintained for ten years.
⒁ Chinese and English interface large screen display, with RS-232 communication interface.
