Arrester discharge counter calibrator - technical articles

The lightning arrester discharge counter calibrator can complete the lightning action counting check and the milliampere meter indication check once. The instrument has built-in battery power supply and the continuous working time is more than 8 hours.
When the GH-6606 arrester discharge counter calibrator is operated on site, the current will be automatically output according to the selected 10%, 20%, 50%, 70%, 100%. When the current is stable, the screen will be at the bottom left corner of T=003. T=000 is always increased to T=007. At this time, the current has been in a stable output state for 7 seconds, and the current data on the counter should be read immediately and recorded. Use this data to determine whether the accuracy of the counter ammeter is in compliance with the national standard.
GH-6606 arrester discharge counter calibrator presses increase, decrease key to increase or decrease discharge voltage, press function key to make count discharge icon, current check icon, data view icon, parameter setting icon cycle is selected

Fully automatic arrester discharge counter calibrator, automatic zinc oxide arrester discharge counter tester

1, arrester discharge counter calibrator count verification function
(1) Output surge current waveform: 8/20 uS (impact current from the occurrence to the peak time of 8uS, from occurrence to drop to 50% peak time 20uS), current peak: >500A.
(2) Output range: voltage output 600V/800V/1000V third gear.
(3) The number of discharges and the discharge interval can be set. (Default: discharge 3 times; discharge interval 5 seconds).
(4) After the discharge is completed, the instrument will automatically discharge, safe and reliable, and prevent personal danger.

2, arrester discharge counter calibrator current check function
(1) Current output: 0.2-10 mA. Automatic output according to 10%, 20%, 50%, 70%, 100% of current;
For example, if the counter current is 2 mA, the output is 0.2 mA, 0.4 mA, 1.0 mA, 1.4 mA, 2.0 mA.
It is convenient for on-site comparison to check the accuracy of the mA meter. Output current time is 7 seconds, output accuracy: 1%
(2) After the current calibration is completed, the instrument is automatically discharged, safe and reliable, and prevents personal danger.
(3) Instrument power supply: comes with rechargeable battery (continuous use for more than 8 hours) or AC 220V.
(4) Data storage: 256 sets of data can be stored
(5) Computer interface: RS232.
(6) Calendar clock: comes with a standard calendar clock, you can manually set the clock, date.
