HVTS-HP series


The HVTS-HP series systems are designed for high-voltage withstand testing of various dielectrics with higher levels of DC or AC voltage (UDC ≤ 140 kV; UAC ≤ 100 kVRMS, f = 50 Hz).

The systems could be used in the field or for laboratory testing.

The system features both DC (rectified) and AC output voltage modes, which allows to use a single HVTS-HP system for testing such electrical equipment as cables, current transformers, switchgear, sectionalizing joints, etc. according to various standards and regulation.

The power output of HVTS-HP series systems ("HP" means "High Power") is several times higher than that of its analogues.

The output current and voltage at the test object can reach 175 mARMS/100 kVRMS and 80 mA/140 kV in AC and DC modes respectively.


HVTS-HP systems feature a digital graphic display indicating all the test settings and operating parameters.

Digital user interface enables HVTS-HP to feature a multi-language menus, as well as viewing test reports, saving test pre-sets, etc.

The system allows to carry out tests in both fully automatic and manual control modes.

In the manual mode, the output voltage level and ramp up rate are controlled by the operator via a rotary encoder.

In the automatic mode, the test voltage is automatically increased at pre-defined ramp up rate and is held on the required level before being reduced to zero upon completion of the test cycle.

Switching between control modes is done by simple push of a button.


Light weight, compact size and trolley-form design of both units of the system enable rapid deployment, quick reconnection and operational comfort during the field testing.

The system consists of two separate modules: the control unit and the high voltage unit.

The test process is controlled from the control unit while an object under test is connected to the high-voltage unit.

Such two-module design allows an operator to remain at a safe distance away from the high-voltage circuit and the object under test.

* The measurement error of a digital tester is specified by the expression: ± [xx% rdg + xx dgt], where the first portion identifies a percentage error relative to the reading, which means it is proportional to the input. The second portion is an error in digits that indicates the counts on the last significant digit of the digital display (the lowest digit in a number, located at the far right of a string). The error in digits is constant regardless of the input and is typically used to represent an error factor of a digital tester.

** The parameters in parentheses apply to the 17.5 versions of the System.

*** Inrush current may be greater. If used with an automatic circuit breaker in the mains supply, a minimum of 63 A (100 A for 17.5 version) breakers are recommended.
