TECHNICAL DESCRIPTION
INPUT VOLTAGE : 380/440 VAC 50/60 HZ
OUTPUT VOLTAGE : UPTO 50 KV AND 200 AMPS
TIMER : DIGITAL (0-99.9 MINUTES)
CONTROL : THE UNIT IS PLC BASED COMPLETE WITH HMI MEMORY FOR OPERATION.
METERING : DISPLAYED ON HMI PANEL
PROTECTION : TRIPPING - A FAST ACTING DC RELAY WILL ISOLATE THE CIRCUIT WHEN THE CURRENT EXCEEDS PRE-SET LEVEL.
OVERLOAD - THIS IS USED AS A SECONDARY PROTECTION IN CASE THE INPUT LOADS EXCEEDS THE PRESET VALUE
OVER VOLTAGE - THIS IS USED AS A SECONDARY PROTECTION IN CASE THE OUTPUT VOLTAGE EXCEEDS THE PRESET VALUE
INTERLOCKING : ZERO START INTERLOCK - THE UNIT WILL HAVE ZERO START INTERLOCKING TO AVOID THE TRANSIENTS ON HV TRANSFORMER AND PROVISION FOR CAGE DOOR INTERLOCKING SHALL ALSO BE PROVIDED.
TERMINATION : THE HT OUTPUT ON SUITABLE HT INSULATOR AND OTHER POINT AT EARTH POTENTIAL WILL BE BROUGHT OUT ON SUITABLE INSULATOR.
HV TRANSFORMER : THE TRANSFORMERS ARE DESIGNED AND MANUFACTURED AS PER IS /IEC GUIDELINES. SINGLE / MULTIPLE STAGE STEP- UP TRANSFORMERS ARE UTILIZED FOR ACHIEVING THE DESIRED VOLTAGE. THE UNITS ARE DESIGNED AND MANUFACTURED USING THE PREEMINENT MATERIAL FROM INDIA AND ABROAD. THE COILS ARE VACUUM IMPREGNATED AND INSULATED WITH HIGH QUALITY EHV GRADE TRANSFORMER OIL AS PER RELEVANT IS AND IEC STANDARD.
