II.Technical features
1. Name and classification
(1) Name: HZDL-2000III Primary Current injection Tester
(2) Environmental group: it belongs to the
Ⅲ
group of instruments in the GB6587.1-86
"General Outline of Environmental Tests for Electronic Measuring Instruments" (that can
be used in outdoor environments).
2. 1 Input voltage: AC 380 50Hz three-phase four-wire.
2. 2 power rate: 10KVA *3
2. 3 Output current: AC0
～
2000A steplessly adjustable, panel with digital display
ammeter
2. 4 Output voltage: >5V
2. 5 Output Waveform: The output current is a standard sine wave with tiny burrs, which
is better than the power system requirements and standards, and the ripple coefficient is
less than 0.3%. Standard sine wave.
2. 6 Measurement accuracy: (using 0.2S grade material) is actually about 0.3; each
current can be smoothly and continuously adjustable, and the accuracy is higher than 0.5
grade. The current and voltmeter display is a true effective value, with high accuracy and
high stability.
2. 7 Output current mode: the true effective value is continuously adjustable;
2.8 Current stability: 0.2%
2.9 Structure: One
2.10 Wiring mode: as required
2.11 Protection settings: over-current, over-voltage
2.2 When the current is 2000A, the current injection time can reach 30 minutes
2.13 Can test the ratio and polarity of CT
2.14 The instrument has a timed emergency stop function
2.15 with wheels, movable
2.16 A B C three-phase can set different current output values for simultaneous output.
