Product Description

Three Phase Relay Tester Relay Test Equipment
 

Characteristics

1,Meets all test requirements on site. The micro-computer relay protection tester has a standard four-phase voltage and three-phase current output, with a voltage of 125V/phase and a current of 40A/phase. It can be used for testing traditional relays and protection devices as well as modern microcomputer protection devices, especially for transformer differential power protection and standby devices, making the test more convenient and perfect.
2,All kinds of technical indicators reach the standard of DL/T624-1997 "Technical conditions of relay protection microcomputer type test device" issued by the Ministry of Electric Power.
3,Classic WindowsXP operation interface, friendly human-machine interface, easy and quick operation; high-performance embedded industrial control computer and 8.4-inch TFT true-colour display with a resolution of 800×600 can provide rich and intuitive information, including the current working status of the equipment and various help information, etc.
4,The relay protection device tester Windows XP system comes with a recovery function to avoid system crash caused by illegal shutdown or misoperation etc.
5,Equipped with ultra-thin industrial keyboard and photoelectric mouse, can be operated like an ordinary PC through the keyboard or mouse to complete a variety of operations.
6,The main control board adopts DSP+FPGA structure and 16-bit DAC output, which can produce a high-density sine wave of 2000 points per week for the fundamental wave, greatly improving the quality of the waveform and the accuracy of the tester.
7,The power amplifier adopts high fidelity linear power amplifier, which ensures the accuracy of small current and the stability of large current.
8,Using USB interface to communicate directly with PC, without any adapter cable, convenient to use.
9,Can be connected to a laptop computer (optional) operation. The laptop computer and the industrial control machine use the same set of software, no need to learn the operation method again.
10,With independent special DC auxiliary voltage source output, the output voltage is 110V(1A), 220V(0.6A) respectively. The output voltage is 110V (1A) and 220V (0.6A), which can be used for relays or protection devices requiring DC power.
11,With software self-calibration function, avoiding the need to open the chassis to adjust the potentiometer to calibrate the accuracy, thus greatly improving the stability of the accuracy.

Reclosing relay
Current relay	Corresponding test items	AC test Current voltage Inverse time current relay DC test	The sequence component relay can be tested in the special sequence component module of "AC test". The inverse time relay can also be tested in "inverse time overcurrent".
Over (under) voltage relay
Sequence component relay
Synchronous check (or phase comparison) relay
Inverse time current relay
Differential relay	DC magnetization characteristics	Differential relay Differential test Harmonic test	During the test, please refer to the wiring mode of "differential test" in the manual for correct wiring.
	Harmonic braking characteristics
	Proportional braking characteristics	Differential test Differential relay AC test
Power (direction) relay	Corresponding test items	Power direction AC test	Before testing the power (direction) relay, the wiring type and the general action boundary of the protection should be determined in advance.
Impedance relay
Synchronizing relay	Corresponding test items	Simultaneous test AC test	The UA and UB of the tester are used as the voltage output of the system side and the side to be paralleled respectively in the "synchronization test" module, which can measure the action frequency, action voltage and phase, and carry out automatic quasi synchronization test.
Frequency relay	Corresponding test items	Frequency test	It can be used to test the slip and closing frequency.
