Our AC High Voltage Tester (High Capacity) is particularly designed for testing cables and electrical equipment in accordance to I.S specifications. Our AC High Voltage Tester (High Capacity) has been designed and developed in-house. These AC High Voltage Testers (High Capacity) are well tested at multiple stages, to ensure consistency and finest quality. This AC High Capacity High Voltage Tester is oil cooled, air cooled or air and oil cooled combined as per needs.
Why Our AC High Voltage Tester (High Capacity)?
Â» Technical Details
Transformer A double wound step up transformer is the most important part of the equipment. The transformer is wound with high quality enameled copper wire & Polyster film/ Paper is provided between the layers. CRGO step core is used for light weight & efficient transformer. Input Voltage 230 or 400 volts single phase 50Hz AC supply Output Voltage Ranges Upto 300 kV Capacity Upto 1000 KVA Off Duty Cycle 15 minutes ON / 15 Minutes Control (a) Knob to control the output voltage from zero to maximum or push button n case of motorized units.
(b) Knob to preset timer
(c) Knob to for tripping Current Control. Metering Voltmeter to indicate output voltage and Ampere meter to indicate the input current are provided upto 25 KVA on primary side.Voltmeter and Amperemeter are provided are provided on secondary side to indicate output voltage and current for higher capacity Termination One end at earth potential & other at HV insulator. Protection (a) Rotary switch and fuse upto 25 KVA.
(b) Switch fuse unit is provided for higher Capacity.
(c) A fast acting DC relay actuates to isolate High voltage in case offault or when current exceeds the preset value.
(d) The unit has zero start interlocking arrangement to ensure that HV will not actuate unless variac is at zero position.
(e) Test cage door interlock where-ever required. Additional (a)The units upto 10 KVA are housed in single housing above 10 KVA are supplied two or more parts as per capacity.
(b) Model upto 25 KVA will keep on indicating the voltage at which the sample under test has failed since the meter is on primary side.
(c) The control panel in all the models is naturally air cooled type.
(d) Control transformer and main transformer oil or air cooled as per the design & capacity of the unit.
