| 6 | Control | Manual Control | Manual or motorized voltage adjustment with push-button HT activation. |
| Digitized Control | Digital panel with optional computer connectivity. | ||
| PLC based | Fully automated: PLC-based system with integrated computer, HMI, and printing capabilities. | ||
| 7 | Metering | Voltmeter: One digital type connected on the HT side to indicate the output voltage. Scale: 0-800 kV AC. Ammeter: One digital type ammeter connected on the earth side to indicate the leakage Current on the sample under test. Scale: 0-40A Applicable only for type -1 i.e. for manual control. For type -2 (Digitized Control) and type 3 (PLC Based Model), metering is self-contained. | |
| 8 | Protection | Tripping | A rapid DC relay cuts power when the current surpasses the set limit. |
| Overload | Serves as a backup safeguard against input load overage. | ||
| Overvoltage | Acts as a secondary defense if the output voltage exceeds the threshold. | ||
| 9 | Interlocking | Zero Start Interlock | The unit will have zero start interlocking to avoid the transients on the HV transformer and provision for cage door interlocking shall also be provided. |
| Earth Interlock | It ensures that HV will not actuate until good earthing is not provided | ||
| 10 | Termination | The HT output on suitable HT insulators and other points at earth potential will be brought out on suitable insulator | |
| 11 | Control Panel | The control panel is designed for five unique purposes. 1 – Control 2 – Measure 3 – Protect (Active and Passive) 4 – Tripping 5 – Annunciate | |
| 12 | Reactor | Our Parallel/Series Reactor (LT and HT) harmonizes with capacitive currents during dielectric testing. Featuring a motorized moving coil and fixed reactor, it achieves a Q-factor of up to 20, ensuring precise resonance for various components and systems. | |
| 13 | HV Transformer | We craft our transformers to IS/IEC standards, offering single and multi-stage step-up options for versatile voltage requirements. Built with premium materials sourced globally, our units boast vacuum-impregnated coils insulated with top-tier EHV grade oil, meeting or exceeding industry benchmarks. | |
