FEATURES
1.Phase Sequence Measurement: The meter accurately measures and displays the phase sequence of a three-phase electrical system, helping to identify the correct order of phases (L1, L2, L3).
2.Phase Rotation Error Detection: It detects and indicates phase rotation errors, allowing for quick identification and correction of wiring mistakes
3.Clear Display: The meter features a rotational disc which rotates clockwise if sequence is correct or rotates anti-clockwise if sequence is incorrect.
4.Compact and Portable: With its compact and lightweight design, the meter is easy to carry and use in different locations and settings.
5.Easy Operation: It is designed with user-friendly controls and intuitive interface for easy operation and quick phase sequence testing.
6.Reliable Performance: The meter delivers reliable and accurate results, ensuring precise phase sequence measurements every time.
7.Durable Construction: It is built with high-quality materials and components, ensuring durability and long-term usage.
8.Power requirement: Self powered, no external batteries or power is required. Which makes it convenient and flexible for on-site phase sequence testing.
The YOKINS Phase Sequence Meter or Phase Sequence Indicator (PSI) is a valuable tool for electricians, technicians, and engineers working with three-phase electrical systems. Its accurate phase sequence measurement and error detection capabilities help ensure safe and efficient operation of electrical installations
SPECIFICATIONS
- Measuring Frequency Ranges: 20-60Hz
- Operational Voltage: 50-500V AC
- Dielectric Strength 2KV / minute
- Three separate 30" long leads in Red, Yellow & Blue for three phases are
- provided with crocodile clips.
WORKING PRINCIPAL
- When correctly connected to three phases R, Y & B. The clockwise rotation of white disc with BLACK ARROW shows that the phase sequence is correct.
- If the rotation is anti-clockwise one of the phases is reversed.
- This works from 50 to 500 volts AC
- This must be used in horizontal position
- Warning : This should not be left on the circuit and be removed immediately after testing the phases.
