DC High Voltage Tester:- Introduction 'RE' DC High Voltage Testers are manufactured for testing cables & other Electrical equipments as per IS/ IEC specifications. The unit consists of transformer, rectifier, condenser, voltmeter and variac etc. All the components are housed in nicely painted sheet metal housing/ powder coated housing.
Special Features:
- Compact in size.
- Built-in safety arrangement for operator.
- Special Insulating Paper is used for transformer winding.
- Easy to operate.
- Efficient after sales service.
- Guaranteed for one year against manufacturing defects only.
Brief Technical Detail:
| Input Voltage |
230 or 400 volts single phase 50Hz AC supply |
| Output Voltage Ranges |
Upto 500 kV |
| Capacity |
Upto 1000 mA on HV side. |
| Duty Cycle |
Continuous for testing and 15 minutes at full load/ or as desired. |
| Control |
(a) Knob to Control the output voltage from zero to maximum or Push Button in case of motorized model. (b) Knob to control the tripping current in steps. |
| Metering |
Moving Coil Digital KV meter and mili Amp meter will be provided to indicate output voltage and leakage current |
| Termination |
The negative and positive terminals are brought out on suitable insulators. Positive or negative polarity can be supplied at Earth Potential on request. |
| Protection |
(a) The unit consists of fast acting DC relay which actuates instantaneously if the testing current goes beyond the pre-set level. (b) The HV will not actuate if variac is not at zero position. (To protect the transformer against transients on HV side & to protect the operator). |
