High Voltage Spark Tester is designed to check and test the quality of cables even at shop floor condition. So, this unit is fitted with castor wheels for easy movement.
The set consists of ?
i. High voltage source.
ii. One electrode arrangement.
Input: 230 volts, 50Hz, single phase AC.
Output(s):
High voltage source
Continuously variable high voltage source from 0 to maximum rated output voltage by smooth variation of autotransformer. Sets are available in different Types depending on the output voltage.
| Type | Output voltage |
| SPTNT-05 | 0 – 5KV at 50Hz. AC. |
| SPTNT-10 | 0 – 10KV at 50Hz. AC. |
| SPTNT-15 | 0 – 15KV at 50Hz. AC. |
| SPTNT-30 | 0 – 30KV at 50Hz. AC. |
| SPTNT-35 | 0 – 35KV at 50Hz. AC. |
| SPTNT- 40 | 0 – 40KV at 50Hz. AC. |
| SPTNT-50 | 0 – 50KV at 50Hz. AC. |
The high voltage source consists of:
- Double Wound High Voltage Transformer having one end of the H.T. winding earthen
- Zero-Start interlocking protection and short circuit protective device are provided.
Metering: Voltmeter is coupled to the primary of the transformer and scaled in kV according to the ratio of the transformer.
Electrode arrangement
The PVC coated cables made to pass through brass ball & chain, which are carrying high voltage. These balls are strongly supported by rugged chain within a protective cage equipped with safety switch. The cable under test enters and leaves the cage through smooth insulating supports for minimum friction.
Since the inside conductor of the cable is earthen, if any pinhole comes, detecting circuit works instantaneously. Length of Electrode chamber is about 100 cm.
Fault Alarm: Audio Alarm is provided which acts when some fault passes through ball chain.
Fault counter: An electromagnetic counter is provided to count the fault.
AC High Voltage Spark Tester at High Frequency i.e. 2.5KHz. is also available.
