HV AC TEST SET

INPUT:       220/240 V.a.c., 50/60 Hz., Single phase, 0.5 Amps.

 

OUTPUT:   0 - 10 kvac at 0 - 10 mA, continuous rating.

                Up to 20 mA may be drawn for short term working.

 

The output is continuously variable from zero to 10 kV by means of the panel mounted regulator.  An output trip is fitted which operates when the output exceeds 25 mA switches off the test set and operates a neon overload indicator.  Primary protection is provided by two panel mounted fuses.  The output is protected by the output trip and a magnetic/hydraulic circuit breaker.

 

METERING: Two 78 mm linear moving coil meters are provided:-

 

                     Voltmeter          0 - 10 kvac

                     Ammeter           0 - 5 - 20 mAac

 

 

Both meters are accurate to +/- 1.5% of fsd.  The voltmeter is direct reading so that he correct output voltage is indicated regardless of output loading.

 

TERMINALS & CONTROLS: The voltage output is supplied via a recessed connector of in-house design arranged so as to prevent accidental contact with high voltages.  Output control is by pushbutton ON/OFF switches.  Indication of HV ON is by a large transformer lamp, MAINS ON and OVERLOAD are indicated by bright neon indicators.  The supply connector is a standard IEC 320 type connector. A 'zero-volt' interlock is fitted which prevents the high voltage circuit from being energised except when the regulator is its minimum position.  A range switch is provided for the output milliammeter which is spring biased to the 20 mA range.  In the 5 mA range position the current trip level is reduced.  The milliammeter is protected by a sealed surge arrestor.

 

COMPONENT QUALITY: Professional grade components are used throughout the test set to ensure long life and good service.  The EHT transformer has resin cast windings to prevent the ingress of moisture and meets the general requirements of BS 171.  The control relays are plug-in replacement types.  The control panel is finished in light blue high gloss stoving and cutter engraved for durability.

 

CONSTRUCTION: The test set is fitted in a robust portable aluminium instrument case with a lid and carrying handles.  A compartment is built into the lid to store the test cables.

 

SIZE:- 370 mm High (including lid) x 440 mm Wide x 285 mm Deep

 

CABLES: A full set of input and output leads are supplied all 3 metres long.
