Test Specifications:
The Automatic Safety Analyzer performs tests in sequence, stopping if a fault is detected and triggering a buzzer alarm.
I) Ground Test
The Ground Efficiency test checks the connection of the ground wire from the plug to the appliance rack by applying 10V AC and measuring the potential drop.
Test Voltage:
-
10 Volts
Test Current:
-
25 Amps
Test Time:
-
0-10 sec
Limit:
-
0-10 Amps
II) I.R (Megohm) Test
The I.R test assesses the strength of ground wall insulation, which may be compromised by dirt, carbon, moisture, or weak wire insulation.
Test Voltage:
-
500 Volts (DC)
Test Time:
-
0-10 sec
I.R Limit:
-
0-200 MΩ
III) H.V Flash Test
The H.V Flash test further evaluates the strength of ground wall insulation at a higher voltage. A sudden surge in leakage current indicates weak insulation and test failure. The test voltage follows the formula: H.V Flash test = (2×E + 1000), where E is the operating voltage.
Test Voltage:
-
0-2.5KV AC (Adjustable)
Test Time:
-
0-10 sec
Overtrip Leakage Current Limit:
-
0.1-10mA
IV) Full Voltage Run Test
This test measures the input current drawn by the appliance at a user-specified voltage. The user sets upper and lower current limits; if the current falls outside these, the test stops, and an alarm is triggered.
Test Voltage:
-
0-270 Volts (Adjustable)
Wattage Limit:
-
0-2000 Watts
Current Limit:
-
0-8 Amps
Power Factor Limit:
-
0.000-1.000
Test Time:
-
0-30 sec
V) Leakage Current Test
This test detects leakage current between internal circuits under applied voltage and the appliance’s external metallic parts.
Test Voltage:
-
0-255 Volts (AC)
Test Time:
-
0-10 sec
Overtrip Leakage Current Limit:
-
0.1-10 mAmps
