As modern power systems place increasing demands on the reliability and maintenance efficiency of reactive power compensation equipment, field testing instruments are required to deliver higher accuracy, better stability, and improved portability.
The VS-2280AS Handheld Three-Phase Capacitor & Inductor Tester is designed for on-site measurement of capacitor banks and reactors in power distribution and transmission systems. It provides a portable solution for electrical parameter testing under complex field conditions, while improving operational efficiency and measurement consistency.
The VS-2280AS supports on-site measurement of three-phase capacitor banks without disconnection of wiring. It is compatible with common connection configurations including Y, Δ, and YN systems.
This design reduces the need for repeated rewiring and helps shorten overall testing time while improving operational safety in field environments.
The instrument adopts a 55Hz excitation source to reduce the influence of 50Hz power-frequency interference commonly present in substations and industrial environments.
Combined with digital control and regulated output technology, the system provides constant-current and voltage-limited excitation to enhance measurement stability under complex electromagnetic conditions.
The VS-2280AS integrates measurement functions for key electrical parameters required in reactive power compensation diagnostics:
- Capacitance: 0.1 μF to 6800 μF
- Inductance: 100 μH to 20 H
- Current: 10 mA to 60 A
- Resistance: 50 mΩ to 20 kΩ
All results are displayed with 4-digit resolution for field readability.
The device supports multiple data storage and transfer options for field and office integration:
- Internal storage for up to 512 test records
- USB flash drive export
- Bluetooth wireless data transmission
- Built-in thermal printer for on-site reporting
These features support documentation, reporting, and integration into asset management workflows.
Designed for field mobility and operational flexibility, the VS-2280AS features a compact handheld structure.
- Weight: approx. 1.6 kg
- Dimensions: 235 × 165 × 75 mm
- Built-in rechargeable lithium battery
- Operating temperature: -10°C to +50°C
The instrument also includes overcurrent and short-circuit protection to improve operational safety in field applications.
| Parameter | Range | Accuracy |
|---|---|---|
| Capacitance | 0.1 μF – 6800 μF | ±(1% rdg + 0.01 μF) |
| Inductance | 100 μH – 20 H | ±(2% rdg + 0.01 mH) |
| Current | 10 mA – 60 A | ±(1% rdg + 0.5 mA) |
| Resistance | 50 mΩ – 20 kΩ | ±(2% rdg + 1 mΩ) |
In substations, capacitor banks are often installed in complex electromagnetic environments, where conventional measurement instruments may be affected by noise and wiring constraints.
The VS-2280AS enables non-intrusive testing of three-phase capacitor banks, supporting routine inspection and condition assessment with reduced rewiring effort.
For distributed power systems with remote and dispersed installations, the device operates on internal battery power, enabling field testing without external supply constraints.
Wireless communication and data storage functions support efficient maintenance data collection and asset tracking.
During installation and commissioning of power equipment, the VS-2280AS can be used for on-site verification of capacitor bank parameters.
The built-in printing function allows immediate generation of test records for multi-party confirmation and acceptance documentation.
Suitable for production line testing of capacitors and related components.
The device supports parameter presets and fast measurement workflows, enabling standardized testing procedures and traceable quality records.
Designed for mobile inspection teams performing cross-site testing tasks.
The wide measurement range and portable design allow the instrument to cover a broad spectrum of capacitor and inductor testing applications in the field.
The VS-2280AS Handheld Three-Phase Capacitor & Inductor Tester provides a compact and efficient solution for on-site reactive power equipment testing.
With its combination of multi-parameter measurement capability, portable design, and field-oriented data management features, it is designed to support routine maintenance, commissioning, and quality assurance workflows across power generation, transmission, and distribution systems.
