Product Description
STMAC-15HS high frequency spark tester is a professional instrument for on-line insulation leak testing in wire and cable industry, which detects little defects such as hole, gap, crack, etc. of wire and cable insulation coating. When defects are found, the instrument records relevant data and automatically generates sound and light alarms, meanwhile sending alarm signal by a relay. It can also send defect data through RS-232/422/485to the PLC or PC for on-line control.
The instrument has a compact structure which is composed of control unit and operate panel as shown in figure. It applies voltage and current double closed loop control, which ensures secure and reliable operations.It can also be remotely controlled through serial communication.
The LC oscillator inside the instrument produces a fixed frequency test high voltage, and exerts the high voltage on tested items through the beads. Under the condition that the tested items are reliably grounded, if any insulation defect is detected, a spark discharge is produced in the insulation coating layer, meanwhile a pulse signal is sent to the detection circuit to increment the leak counter, so that the alarm device produces sound and light alarms and eventually detects the insulation leak.
Output Voltage: 0 ~ 15KV (RMS), sine wave.
