Output : Continuouslyvariablefrom0to 50 Kv'or' 0 to 60 Kv,'or' 0to 100Kv,'
:
CAPACITY: 1000VA(1KVA )
DUTY: The Oil Test set will be designed for"INTERMITTENT" RATING

NATURE OF COOLING
The transformer will be epoxy resin cast type air-cooled type.

GENERAL ARRANGEMENT
The set will be comprising of the H.T.transformer, controlcircuity Test cell with electrod & guage and will be supplied in portable air cooled sheet metal casing with powder coating of control cubical & H.T.transformer.

CONTROL:
- One continuously variable Auto-Transformer for smooth variation of out put    voltage
- Beside the ON/OFF switch, fast acting Automatic tripping mechanism for    protection of H.TT. ransformear gains to verloading on flash over.
- One zero start inter locking device.
- Two pilot lamps to indicate mains 'ON' & H.T.circuit 'ON'.
- One input supply cable with 3- pin plug.
- One memory effect voltmetetor show the break down voltag even I   after    the high voltage circuiti stripped off.

MODE OF OPERATION :
Sets are available either in manual or in motor; operated mode. Beside motorized auto-transformer regulator for motorizesd et motoro perated Auto-transform can be operated in manual through switch.

H.T. TRANSFORMER
High voltage Transrormer ration is 230v/ 50 Kv or 60 Kv or 100Kv or 120Kv with centre tap HV winding earthed .

TEST VESSEL :
The test vessel (OilCell)fittedwith two brasss pheres of diameter between12.7 to 13mm, placed at a distance of 4 mm or 2.5mm on sides of test vessel made from non-absorbenint sulating material.

COVER:
Sets will be provided with transper an hight impacat crylic sheet cover for
covering the H.T.side with suitable inter-locking device.
