Wireless Phase Tester

HMEC-2 Wireless Phase Tester，for MV overhead distribution circuit ，used for detection of high-voltage power grid closing point on both sides of the phase sequence is the same. Two power line connection before must check phase sequence, or line may be short circuit. The instrument suitable for 380V ~ 220KV power transmission line, and can test whether line charged. The Instrument adopts the wireless transmission technology, safe and reliable operation, easy to use.

The instrument consists of two transmitters (x and y) and a receiver. Two emitters can be judged whether line charged, and launch phase signal. Receiving meter receives two emitters’ signal, to judge whether the same on both sides phase sequence.

1.Insulating rod before using should be voltage withstａnd test.

2.The standard configuration insulating rod length is 3 m, corresponding voltage for ≤ 220 KV. If the measurement circuit voltage higher than 220KV, please use the length of more than 3 meters of the insulating rod.

3. Operation hａnd position not more than insulating rod handle position.

1.Accuracy:When phase sequence is same: the error≤ 5 °.

2.The frequency accuracy：±0.1HZ.

3.Measuring voltage range is 380V - 220KV .

4.The transmitter and the receiving host transmission distance is more than 130 meters, the maximum distance between the two transmitters is about 260 meters.

5.Results (in phase, interphase) using A standard, phase difference acuity ≥30 ° for out phase, the phase difference < 30 ° are in phase.

6.Human voice prompt, male voice "in phase", female voice "phase-out".

7.Screen shows two lines at the same time of phase difference, frequency, waveform and the vector diagram.

8.The host shows battery, half an hour without automatic shutdown operation.

9.Two emitter and receiver use rechargeable lithium battery.

10.Have high pressure test report and the function of the phase sequence.

16.The weight：about 3.6KG.

17.Instrument package size: 56 cm long * wide 26 cmm * 13 cm high.

（1）Introduction of instrument appearance

（2）Introduction of instrument operation

Lamp:

(a) “Different" light: two line phase sequence is different.

(b) “Same" light: two line phase sequence is same.

(c) “Charging" light: Battery is charging.

(d) “Full" light: Battery is fully charged.

Key:

(1) long pressing to switch on up or shut down.

(2) Short press the close distance measurement and distance measurement switching.

Supplement:

1)Top right corner have power indicator.

2)The bottom jack is charging interface.

Lamp:

Testing: Two lights kept flashing.

Charging: fog lamp is red.

Charging complete: fog lamp is green.

Buzzer:

Exposure to high voltage electric lines the buzzer rang 2 seconds, said the line charged.

Install screw hole:

To connect with Telescopic insulating rod.

Charging jack:

To connect with the charger.

(3) The instrument examination method:

Method 1: using the configuration of the emitter mains special test line reference figure (1) connection, 220 v mains plug. If the emitter buzzer, two light is flashing, receiving host shows the frequency of the corresponding information, the transmitter and the host are normal.

Method 2: the emitter hooked up to the corresponding voltage grade of electric circuit inspection (as shown in figure 2) or use the high pressure test equipment, simulation of high voltage line for inspection instruments (as shown in figure 3). If the emitter buzzer, two light is flashing, receiving host shows the frequency of the corresponding information, the transmitter and the host are normal.

Tip: 1) transmitter direct contact with high pressure, apparatus started about 4 kv voltage.

2) use mains special test line, equipment start-up voltage of about 5 v
