Three-phase multi-function volt-ampere phase meter standard needle-type clamp-type current transformer high measurement accuracy

April 25, 2021

Function introduction

1. The instrument adopts 65×50 liquid crystal display, high backlight display, intuitive and clear.

2. The current amplitude of the instrument is flat, and the phase can be accurately measured in the range of 5mA-10.OA.

3. Three-phase multi-functional volt-ampere phase meter instrument automatically detects the range without the need for shifting, direct function key operation, and displays voltage (U), current (I) true RMS, display voltage and voltage (UU), voltage and current Various phase relationships of (UI), current and current (II), real-time measurement of active power (P), reactive power (Q), frequency (F), and power factor (PF), and Chinese shows positive and negative phase sequences.

4. The instrument can automatically determine the wiring error of the meter and identify it according to the group number. With the instructions, it can easily find the wrong position of the meter.

5. Instrument built-in rechargeable lithium battery power supply, can work continuously for 18 hours, even when the backlight is turned on can also work for 8 hours, no external power supply, with a lack of electricity instructions.

6. The instrument is equipped with a pin-cushion-shaped Current Transformer, which has a high measuring accuracy and a strong anti-jamming capability. It is especially convenient for use in places where dense cables are used.

Instrument use:

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.
