Test Set
SPECIFICATION FOR "NTPL" MAKE
30KV/100mA AC HIGH VOLTAGE TEST SET
- SERIES: AHVMNDR2
- TYPE: 030K100m
"NTPL" make AC High Voltage Test Set is suitable for Power frequency applied voltage test on transformers, motors, insulators, cables etc. The set is capable of giving continuously variable High Voltage from 0 to 30KV.Technical features
- Input: 230 Volts, single phase, 50Hz, AC.
- Output: Continuously variable from zero to 30KV AC.
- Capacity: 100mA
- Duty: Intermittent i.e. 5 minutes ON, 10 minutes. OFF.
Output voltage variation: By means of manual rotation of regulator.Over load tripping adjustment: At 25mA, 50mA & 100mA.Over Voltage Indication provided.The above test kit will be in 2 units i.e.
- Control & Measurement Unit.
- AC HV Transformer Unit.
All the above units will be provided with wheels for easy movement.CONTROL & MEASUREMENT UNIT
- Power Mains ON – OFF operation is done by means of an ON – OFF switch along with 'MAINS ON 'lamp indication & Fuse.
- HT' ON – OFF switch along with ‘HT ON’ lamp indication.
- Continuously variable autotransformer of suitable capacity to increase the output test voltage up to the required voltage level.
- Zero start interlocking will be provided to ensure that the HV circuit cannot be energized unless the regulator is initially kept or brought back to zero position.
- Automatic tripping mechanism for protecting the HV transformer against over loading. The tripping mechanism can be adjusted at different values as mentioned above. After tripping, High Voltage will be switched OFF.
- Analog Voltmeter generally connected to the LT side and scaled in KV. Accuracy ±1.5% of FSD.
- Analog milliammeter along with 'Press to read mA' push button to read the leakage current.
- In case of the voltage exceeds the maximum rated value a lamp & buzzer will indicate over voltage.
- Memory device along with push button switch enables the meter of the Test Set to indicate the breakdown voltage by pressing the ‘Memory’ switch even after the high voltage circuit is tripped OFF.
The whole control circuitry will be housed within a sheet metal cabinet treated with anti-corrosive prima and powder coated.HV TRANSFORMER UNIT
- HV Transformer used in the Test Set will be cast resin type of suitable capacity. The HV winding of the high voltage transformer is of graded insulation one being connected to the earth potential through a CT operated milliammeter & tripping device, while the other end remains in floating condition as HT Terminal.
- The transformer will be designed to withstand frequent intermittent spark over or short circuit conditions under which such testing transformers are designed to operate.
Optional at extra cost
- Digital meters
- Motorisation of voltage regulator
- Timer
- Other special features
DOCUMENTSOperation Manual, Works Test Report, Warrantee Certificate will be supplied along with the set.Approx. Dimensions (LXBXH)
- Control Panel: 505mmX 320mmX 290mm
- HV transformer (without HT bushing): 340mmX330mmX 415mm
Approx. Weight
- Control Panel: 27.5Kg.
- HV Transformer: 52.3Kg.
