‘RE’ DC High Voltage Test Set is used for testing cables, generators and other electrical equipments as per National and International specifications. The unit consist of variac, transformer , rectifier, condenser, bleeder, filter etc. All the components are housed in sheet metal housing or specially designed fiber glass housing which are coated with anti tracking paints.
- Easy to operate.
- Rugged and compact in construction
- Full-wave voltage doublers circuit / Multiplier Circuit.
- Zero start interlock and earth interlock
- Meter accuracy +- 1% full scale
- Air Cooled Units / Air and Oil Cooled units
- Digital meters for easy readability.
- High Voltage Surge protection.
- Discharge Rod with 10 meter Long Lead with Clamp.
|DC High Voltage Test Set (Stationary Type)
||220/230V or 380/400, 50HZ / 60HZ AC Supply
||Up to 500kV
||Up to 1000mA
||Continous for Testing or 15 minutes at full load
||Type 1- The unit can be manual control for voltage variation and push button controlled for HT actuation.
Type 2- The unit can be complete with on board digitized panel with or without computer connectivity.
Type 3- The unit can be PLC based complete with computer, HMI memory, printer etc. for operation.
||The metering can be provided via resistive voltage divider for direct HT voltage and current measurement
||The negative and positive terminal are brought out on suitable insulator. Positive and negative polarirty can be supplied on earth potential on request.
||The unit consist of fast acting DC relay which actuates instantaneously if the testing current goes beyond the preset level.
The HV will not acuate if the variac is not at zero position ( To protect the transformer against transient on HV side and to protect the operator)
||Silicon diodes with RC networks are used for rectifictaion in bridge or double or multiplier or half wave circuit.
||A suitable cpacity filter is added to ensure that the ripple is less than 2%.
