DC WITHSTANDING VOLTAGE/ INSULATION RESISTANCE TESTER TOS9213AS The maximum system voltage is the key for insulation test of PV (photovoltaic) modules. It can also be used to check for PID. The insulation tests in international standards IEC61215 Edition 2.0 2005-04, IEC61646 Edition 2.0 2008-05, and IEC61730-2 2004-10 are composed of 3 tests: the withstanding voltage test, insulation resistance test, and wet leakage test. The TOS9213AS is capable of insulation tests up to a maximum system voltage of 1500 V. Capable of tests up to a maximum system voltage of DC WITHSTANDING VOLTAGE/ INSULATION RESISTANCE TESTER IEC61730-2 standard test The applied voltage varies depending on the applicable class in IEC61730-2. For Class A, the voltage is raised at a speed of 500 V/s or less to [2000 V + 4 times of the maximum system voltage] and then maintained for 1 min. Example: With a mega-solar system that has a maximum system voltage of 1500 V, the applied voltage is [2000 + 4 x 1500] V = 8000 V. * (Excluding tester accuracy and similar factors) Image of insulation tests with the TOS9213AS PV module Frame Insulation resistance test and wet leakage test With each standard, the voltage is raised to a speed of 500 V/s or less to 500 V or the module maximum system voltage (whichever is higher) and maintained at that voltage. As the maximum system voltage in solar power generation projects continues to trend higher, the TOS9213AS can raise the DC voltage that is applied at the insulation resistance test up to 1500 V. Electrode Connect the HIGH terminal to the short-circuited output electrodes. Connect the LOW terminal to the frame. Reproduction of PID When performing tests for PID (Potential Induced Degradation), which is a problem with current PV modules, a negative polarity DC power source is required. By turning OFF the timer setting in the TOS9213AS insulation resistance test mode, it is possible to perform these tests with the TOS9213AS in the same way.(Maximum current capacity: 1 mA up to 1020 V, 0.1 mA at or above 1020 V) Features/ Functions 10 kV / 5 mA, maximum output power of 50 W in DC withstanding voltage test. -25 V to -1500 V / 0.01 M 9.99 M insulation resistance test. Conforms to international standards including IEC61215 Ed2.0, IEC61646 Ed2.0, and IEC61730-2. Low output ripple of (100 Vp-p at 10 kV) in consideration of capacitive load. TOS9213AS * The module connection method for PID reproduction is the same as for the insulation tests. By selecting the TOS9213AS insulation resistance test mode (IR), the applied voltage will have negative polarity. The rise time control function allows the voltage build-up rate to be set. Also includes a discharge function. Judgment of the insulation resistance test can be selected between resistance value and current value. Capable to apply high-voltage and monitor current for PID.
