In the event of a power outage the automatic discharge

system remains in its current position and no automatic

discharging occurs. In this case however, discharging may

be manually initiated using a rip cord and the gas pressure

spring triggered in the process.

Control Unit with one-button-operation

The device is controlled using the standard Megger one-

button-operation with a quick selection menu as known

from other measurement systems. The display of the pro-

gression over time of current and voltage and the storage

of measurement data takes place on an automated basis

at a frequency of 4 Hz. Reports can be generated via the

Easyprot reporting software and storage of the datasets on

a USB Stick.

To ensure safe operation of the system during an ongoing

DC voltage test or cascade burning, the system automati-

cally shuts down in the event of an overcurrent (manually

adjustable) or overvoltage. This avoids major damage to the

test system and/ or test object in case of malfunctions or

breakdowns.

DESCRIPTION

Megger offers DC test devices for a wide range of voltages

and applications. The HVDC test set is a high-performance,

portable testing system that can be used to evaluate all kind

of high-voltage-direct-current components, in line with the

applicable regulations regarding the generation of HVDC

voltages of up to 800 kV.

The set is predominantly used by power supply companies,

service providers, cable installers and cable manufacturers

for DC testing on high-voltage systems and cables. In

addition, surge arresters, HVDC transformers or insulators

can also be tested and leakage measurements conducted.

The system is suitable for laboratory testing as a permanent-

ly installed installation system, and as a for mobile on-site

applications being stored in a trailer. The modular structure

of the test system facilitates its set-up on site, and allows it

to be adapted to the particular measuring tasks. The high

voltage system is water resistant and features an ammonium

sulphate solution which protects the cascade from surges

caused by breakdowns in the test object.

Apart from DC testing, the short-circuit-proof output circuit

and the system’s high power, enable the HVDC Systems use

during fault location as a burner for modifying high-imped-

ance and intermittent faults.

Each DC voltage test is automatically earthed by the motor-

ised discharge system and thereby set to a safe operational

state. This takes care of secure earthing as well as unearth-

ing before the start of a new measurement. The modular

cascade set for generating high DC voltage is optionally

available with positive polarity.
