Three-phase multi-volt ampere phase meter measures the phase difference between voltage, current, and voltage

January 10, 2024

Overview:
Three-phase multi-volt ampere-phase analyzer uses high-performance single-chip microcomputer as the central processor, adopts three independent voltage channels, three independent current channels, three current clamps, large-screen graphics dot-matrix liquid crystal display, and long-lasting nickel The hardware design of the hydrogen battery, battery management circuit, non-volatile memory, high-precision clock, and serial data interface has reached a new level of portable phase measurement and multi-function instrumentation, which is unmatched by traditional double-clamp phase meters.
The three-phase multi-functional voltmeter is the ideal portable phase measurement and multi-function instrument. Use this instrument,
1. It can measure up to three AC voltages at the same time;
2. It can measure up to three alternating currents at the same time without disconnecting the circuit under test (through the clamp-type current transformer);
3. Measure the phase difference between voltage, current, voltage and current;
4. Measurement frequency;
5. Measuring power and power factor
6. Measure three phase sequence;
7. Measure the zero-sequence current.
Since the instrument has the above basic functions, its use is extremely wide:
1. The identification of inductive and capacitive circuits;
2. Relay protection phase relationship between CT groups;
3. Check the transformer wiring group;
4. Check whether the active energy meter wiring is correct or not;
5. Judging the speed of the electricity meter and reasonably collecting electricity charges
6. Use as a leakage current meter.
Therefore, this instrument is an ideal instrument for secondary circuit inspection of the power system relay protection and measurement professional, industrial and mining enterprises, petrochemicals, and metallurgical enterprises.
Product main features:
1. An instrument has seven functions: three-phase voltmeter, three-phase clamp-type ammeter, phase meter, phase sequence meter, frequency meter, power meter, power factor meter in one.
2. Measure (up to three phases) electrical parameters and display vector hexagons.
3. Accurate measurement of small clamp current can be used as leakage current meter.
4. Large screen dot matrix LCD, friendly man-machine interface.
5. Long-term nickel-metal hydride battery, AC and DC power supply, convenient for on-site use.
6. Serial data interface, can connect micro-printer and communicate with computer
7. Screen (data, graphics) function for easy access.
8. Self-ranging, software calibration.
9. High precision clock, battery capacity bar analog display.
10. All-digital, high reliability.
