Scale :  0-500mA Applicable only for type -1 For type -2 and type 3 metering is self contained
7	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 Overvoltage -  This is used as a  secondary protection  in case the output voltage exceeds the preset value
8	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. Earth interlock- It ensures that HV will not actutae untill good earthing is not provided.
9	Termination	The HT output on suitable HT insulator and other point at earth potential will be brought out on suitable insulator
10	Control Panel	The control panel is designed for five unique purposes. 1 -Control 2- Measure 3- Protect (Active and Passive) 4- Tripping 5 -Annunciate
11	HV Transformer	The transformers are designed and manufactured as per IS /IEC guidelines. Single /  Multiple stage stepup transformers are utilized  for achiving 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.
