Description

“NTPL” make 5KV/50mA AC HIGH VOLTAGE Test Set

SERIES: AHVMNDR1

TYPE: 005K050m-TM

APPLICATION:

“NTPL” make AC High Voltage Test Set is suitable for Power frequency applied High Voltage test for which the test parameters are within the technical scope of output of the test set. The set is capable of giving continuously variable High Voltage from 0 to 5KV AC.

Technical Features:

Input                   :    230 Volts, single phase, 50Hz,

AC. Output        :    Continuously variable from zero to 5KV. Capacity : 50mA max. at HT side.

Duty                    :    Intermittent i.e. 5 mins. ON/10mins. OFF.

• Output voltage variation: By means of manual rotation of
• Over load tripping adjustment: At 25mA &

• Power Mains ON – OFF operation is done by means of an ON – OFF switch along with ‘MAINS ON’ lamp indication & Fuse.
• ‘HT’ ON – OFF push buttons along with ‘HT ON’ lamp indication.
• Continuously variable autotransformer of suitable capacity to increase/decrease the output test voltage up to the required voltage level.
• Automatic tripping mechanism for protecting the HV transformer against over loading. The tripping mechanism can be adjusted at values as mentioned above. After tripping, High Voltage will be switched OFF.
• 31/2 digit voltmeter connected to the LT side and scaled in KV meter. Resolution: 0.01KV.
• 31/2 digit milliammeter along with ‘PRESS TO READ mA’ push button to read the current at HT side. Resolution: 0.1mA for both 25mA & 50mA current range.
• A ‘TIMER’ (999secs.) will be provided to count down the duration of applied HV. A buzzer will indicate the end of time for HV application. ‘RESET’ facility will be provided.
• In case of over voltage a lamp & buzzer will indicate over voltage.
• Memory device enables the meter of the Test Set to indicate the breakdown voltage by pressing the ‘MEMORY’ push even after the high voltage circuit is tripped OFF.

HV Transformer:

HV Transformer used in the Test Set will be cast resin type of suitable capacity. The HV winding is of graded insulation, one end being connected to the earth potential through a milliammeter circuit & tripping device, while the other end remains in floating condition as HT potential.

The transformer will be designed to withstand frequent intermittent spark over or short circuit conditions under which such testing transformers are designed to operate.

The whole control circuitry will be housed within a sheet metal cabinet treated with anti-corrosive prima and powder coated.

Documents:

Operation Manual, Works Test Report, Warrantee Certificate will be supplied along with the set.
