XS series operating manual

1 DIELECTRIC STRENGTH TEST 50VA (hipot 50VA test)

XS50 / XS56 (5kVAC / 6kVDC)

Output voltage

 Alternative 50 or 60Hz ( DC voltage on XS56 model).  From 100V to 5 kVAC in one range (100V to 6 KVDC).

 Stability < 1% for V mains of 10%.  Positive pole to earth with DC voltage  Ripple < 1% for Is=100 µA with DC voltage  Accuracy of the output voltage: (2%+50volts) in relation with the set value for voltages

between 100 and 5000 volts (6000 volts for DC) and for a current < 100 µA in the fault detection modes : I, IMAX or I+IMAX.

 Discharge of the tested specimen and of the internal capacitor through a 1.5 M resistance with

DC voltage

Voltage reading

 By kilovoltmeter directly connected to the output terminals.  Accuracy : (1.5%+20 volts) of the read value.  Display by 600 points digital indicator.

Short circuit current

 <15 mA in AC for the maximum voltage adjustment.  <15 mA in DC for the maximum voltage adjustment.

Breakdown detection

Current variation mode: I

The TEST detector automatically carries out the subtraction between the current which flows normally in the device under test (I=U/Z) and the one which occurs at the time of a fault (I'=I+Ifault).

 Amplitude adjustable between : 1 mA and 10mA 10% by 1 mA step.  Width of current pulse : 10µS 20%

XS user manual v0.55 - 11 -

XS series operating manual

Maximum current limit : IMAX

Adjustable from 0.01 mA to 9.99 mA by 0.01mA step. The unit monitors permanently the current flowing through the sample under test and compares

according the 2 following possibilities:

The high limit ( IMAX) > 0 , the low limit (IMIN) is set to 0

 If the measured current is > or = to the IMAX, then the test is FAIL ( breakdown)

The high limit ( IMAX) > 0 , the low limit (IMIN) is set to a value < IMAX

 If the measured current is < IMAX and > IMIN then the test is PASS, otherwise the test is

FAIL ( breakdown or I < IMIN)

WARNING : This detection mode can require between 200 and 300 msec. for the limit detection, and during this time the current can increase quickly over the limit .

Fast maximum current limit : F(ast)IMAX

Specifications are identical to the IMAX detection mode . However in the FIMAX mode the breakdown detection is fastest (20 msec.) than in IMAX mode because the comparison with the current limit is performed directly by electronic circuits and not by the embedded software.

Accuracy of the detection :

DC: +/- (5%+ 2U) AC: +/- (10%+2U)

Fast maximum current and variation current limit : FIMAX + I

This mode combines the FIMAX mode and the Delta I mode.

Maximum current and variation current limit : IMAX + I

This mode combines the IMAX mode and the Delta I mode.

Minimum current limit : IMIN

In the above detection modes it is possible to set a minimum value of current flowing through the specimen under test : IMIN value adjustable from 0.00 mA up to 9.99 mA to insure that the specimen under test is correctly connected.

Without detection

In this mode there is no current monitoring.

There is no output high voltage adjustment according to the load. WARNING,

Permanent operation on heavy loads in this mode can heat the electronic amplifier. The internal fan will start automatically to reduce the temperature, with a possible stop of the HV generator for safety reasons.

XS user manual v0.55 - 12 -

XS series operating manual

Permanent current measurement

 Direct reading of the current on a shunt resistance in the test circuit.  Display of the value on a 999 points digital indicator.

 Accuracy : (2.5% + 2 U) of the read value (1U=0.01mA).

In VDC accuracy is given for resistance loads > 1 M.

Fault indication

 By message on the LCD display, red and green LED, and audible signal (possibility to inhibit).  Memory storage of the breakdown voltage.  Memory storage of the leakage current in IMAX mode.  Cut off of the high voltage at the first zero crossing of the control sinusoidal signal of the HV

transformer, thus without over voltage.

Timer

(mode) MANUAL

The timer is not used during the test . The voltage output is manually controlled by pressing on the UP/DOWN arrows. The test stops when a breakdown occurs or when pressing on the red push button on the front panel.

(mode) DEFAULT

The timer is not used during the test . The voltage output is defined in the parameter VOLTAGE line. The test stops when a breakdown occurs or when pressing on the red push button on the front panel.

(mode) AUTO

The test is defined by three consecutive times during which the output voltage rises linearly up to the preset value ( RISE time) , then is hold to the preset value ( HOLD time) and finally bring back to zero ( FALL time). The RISE and FALL times can be set from 0 to 1 sec. by 0.1 sec. step and from 1 to 999 sec. by 1 sec. step. The HOLD time can be set from 1 to 999sec. by 1 sec. step.

(mode) DEFAULT

The timer is not used during the test. The voltage output is defined in the parameter VOLTAGE line. The test stops when a breakdown occurs or when pressing on the red push button on the front panel.

(mode) AUTO

The RISE time can be set in seconds, from 2 to 60 sec. by 1 sec. step, or can be set in V/s. The FALL time can be set in seconds, from 0 to 60 sec. by 1 sec. step, or can be set in V/s. In the case of ramps set in V/s, the value translated into seconds must stay between the time limits given above. For example, if the test voltage is 5000VDC and the ramp up set by the user is 5000V/s, this value will not be accepted because it is equivalent to a ramp up time of 1s < 2s, whereas if the value of the ramp up is 2400V/s, it will be accepted.

The HOLD time can be set from 1 to 999sec. by 1 sec. step.

Detection of capacitive samples

Before starting a test, it is possible to detect whether the sample is properly connected to the unit or not. This is possible provided that the sample to test has a capacitive value of at least 10nF. If the detection is activated, a pulse of 100V magnitude and of 1s duration is generated, right before the hipot test starts. The capacity value is deduced from the current measured during this pulse. If the capacity value deduced is high enough, the sample is considered detected and the test continues. Otherwise, the test is stopped, and the hipot voltage is not generated.

By default, the detection threshold is set to 10nF. When the EXPERT mode is activated, it is possible to configure this detection threshold between 5nF and 10nF by 1nF steps and between 10nF and 1000nF by 10nF steps.

Precision on the detection threshold : ±40%

Ex: To detect samples of at least 10nF capacitive value, a threshold of at least 10nF(1-40%)=5nF should be set to ensure that the absence/presence of the sample will be detected every time. Likewise, a detection threshold of 10nF ensures the detection of absence/presence of samples with capacitive values of at least 10nF/(60%) = 17nF.
