Seaward Electronic, represented in Australia by Emona Instruments , have introduced SD300 discharge device for safe discharge of stored energy in large capacitors and electrically charged equipment.
The SD300 discharge device is designed to enable engineers to safely discharge high power capacitors used for power factor correction and energy storage applications in power generation, petrochemical, oil and gas, processing and motor drive control industries.
The SD300 unit incorporates a number of features to counter unauthorised and dangerous practice of discharging high power capacitors with wires or screwdrivers.
The portable new SD300 is a self-contained safe discharge device that is designed to protect the operator or the test engineer from danger and the equipment under test from potential damage.
Seaward Electronic SD300 is a long life battery powered tester that is designed for use in situations with a maximum voltage of 1000V DC and maximum capacitance of 1200uF.
The failsafe design of the SD300 discharge device incorporates a two-handed push button operation to initiate and maintain the energy discharge, ensuring that the operator cannot come into contact with the live circuit. In addition, the operator is isolated from the discharged energy by an insulated and robust instrument case rated at IP66.
The SD300 instrument comes with shrouded fused test leads and includes an inbuilt test lead and fuse proving facility. Other safety features include an automatic pre-use self test, protection against prolonged connection to live operating circuits and monitoring of critical component temperatures with automatic cut off.
Once activated, the stored energy is discharged in 30 seconds and both analogue meters and LEDs provide a visual indication of the state of the stored energy. The displays also indicate whether the discharged current is AC or DC and the polarity.
The SD300 discharge device provides an effective solution for the safe discharge of electrically charged equipment.
