The PA-9Plus has been introduced based on the successful PA-9 and has enhanced standard key features including a faster Digital Signal Processor (DSP) to support future evolving features and capabilities, a full 12MB of internal, nonvolatile memory and incorporated auxiliary power input capabilities.

To address worldwide applications, the product is CE marked and adheres to applicable European standards (EN50160, IEC61000 series, IEEE1159, IEEE519).

•   Direct digital reading.
•   Built-in discharge circuitry.
•   Two independent measuring channels.
•   Tests operation of on-load tap-changes.

The Transformer Ohmmeter is a line-operated, field-portable instrument designed specifically to measure the dc resistance of all types of magnetic windings safely and accurately.
Its predominant use is the measurement of the dc resistance of all types of transformer windings within the defined ranges of current and resistance.
It can also test rotating machine windings and perform low-current resistance measurements on connections, contacts and control circuits.

Three features combine to make this instrument unique: dual measurement, load tap-changer testing and safety shutdown.

Main Functions:

Time measurement:

•  To simultaneously measure the fixed breaking, closing and the
    asynchronous time of twelve (12) fractures, together with the
    bouncing time and bouncing frequency.

Measurement of displacement and speed:
•  To measure simultaneously the three-phased switching distance,
   over-travel, total run, maximum bouncing amplitude and breaking
   (closing) speed.

Circuit breaker dynamic characteristic test:
The operating voltage is provided by the built-in DC power supply.

Circuit breaker coil current waveform measurement.
Re-closing breaker test:
The built-in DC power supply provides the operating power supply for closing the HV switch, the time delay of breaking-closing-breaking in the closing test can be set.

Display Parameters:
• To display and print coil current-time curve.
• To display and print three-phase breaker displacement curve.
• To display and print three-phase breaker speed-time curve.
• To display and print three-phase breaker status-time curve.
• To display and print three-phase breaker displacement-speed curve.

Accessories:
Distance Transducers, Angle transducers, Connecting cables.
