The above test set is suitable to perform AC High Voltage Power Frequency test on transformers, motors, cables etc. Leakage current can be measured at desired pressure and this set can be used as a source for cable fault burning.
Input : 230 volts, 50 Hz., single phase, AC. However, sets with other input voltage & frequency are also manufactured if mentioned by the customer.
Output(s)
AC Mode : Continuously variable from 0 to maximum rated output voltage. Spread over a wide range from several VA to hundreds of KVA.
Tripping current: 25%, 50% & 100% of the rated current capacity.
DC Mode : Continuously variable from 0 to maximum rated output voltage.
This DC HV output can be suitably used in two modes.
They are: –
1) Cable fault-burning mode.
2) Cable insulation testing mode.
Only one output mode will be available at a time by brief manual change over.
Duty cycle: Intermittent i.e., 5 minutes ON, 10 minutes OFF. However,test sets of continuous or other duty cycles can also be manufactured at extra cost.
Series: ADHVXXYYU; XX denotes Manual operation of the set (MN) or Motor operation of the set (MT). YY denotes type of transformer i.e. cast resin type (DR) or oil cooled type (OC). U denotes no. of units.
This Series will be repeated for both AC & DC mode as Series1 & Series 2
Type1: X1X1X1KY1Y1Y1 m; X1X1X1 denotes the maximum rated AC output voltage.Y1Y1Y1 denotes the current capacity in mA.
X1X1X1KY1Y1Y1 A; Y1Y1Y1 denotes the current capacity in Amp.
Type2: X2X2X2KY2Y2Y2 m; X2X2X2 denotes the maximum rated DC output voltage. Y2Y2Y2 denotes the current capacity in mA.
Protection: Overload & short circuit provided. Zero start interlocking along with Overvoltage
alarm & indication are provided.
Metering
AC mode: Voltmeter, Rectifier type milliammeter.
DC mode: Micro-ammeter scaled and connected to the HV resistor chain for direct DC HV
measurement.
DC milliammeter to measure DC leakage / burning current
HV Transformer:
The Transformer will be indoor pattern cast resin trolley mounted type with one end of the HV winding earthen through low impedance circuit element.
Rectifier unit:
This unit consists of diode chain, filter capacitors and resistor chain. The whole DC circuit element will be coupled to the transformer & control by simple & short manual operation.
Discharge rod: A discharge rod is provided with the set.
