High Voltage Test Equipment for Instrument Transformer and Switchgear Testing
Instrument transformer and cable testing is central to the safety and integrity of power grids. The primary test and measurement technology with portable high voltage test devices is an essential solution for checking transformer components and cable fault detection. These technical measures include testing the insulation resistance and accuracy, especially for apparatus testing in the industry. It depends on the highest level of control and reliability. Over the years, the manufacturing high voltage test technology has constantly evolved to meet global customer requirements in modern power grids. To ensure the maintenance of power supply, it is essential that these systems operate reliably under all conditions.
High Voltage Test Equipment: HV Testing and Safety Parameters
High voltage (HV) is an electrical voltage that operates above 1000 V for ac voltage or 1500 V for dc in accordance with industry standards. At lower frequencies, the current flows through cables and conductors; here, there is a danger to persons when active parts are touched directly. In the high voltage dc range, our products specialize in detecting potential breakdown risks and partial discharge phenomena. The method we recommend involves testing medium to high-range cables for electrical test integrity. Our diagnostic solutions ensure comprehensive testing capabilities across various applications.
The safety of electrical products and apparatus testing is checked with a VLF (very low frequency) test – including switchgear testing capabilities. These digital devices are capable of producing accurate results in factory and manufacturing environments. The test devices meet all relevant VDE standards and thus enable affordable diagnostic testing of high-voltage and insulation strength. The focus is not only on the precise output measurement of the generator’s high voltage, but also on the technical requirements for operator safety. For this reason, state-of-the-art digital control solutions are essential for our range of products. These ensure not only safe operation but also preferred output accuracy in all testing scenarios.
Primary test equipment (constant current sources)
The primary testing technology affects manufacturers who specialize in circuit breakers, molded case circuit breakers or motor protection switches. Our selection of products serves energy management companies, industrial parks, and medium-sized facilities requiring reliable testing solutions. The advanced technology enables comprehensive testing across diverse industry applications.
Constant current source: RPEO4
Our digital constant current source RPEO4 is a fully electronic output generator up to a maximum of 4 kVA with AC and DC capabilities. The parameter range includes cable testing with thermal and/or magnetic tripping. In addition, functions for long-term measurement with a constant or increasing output are used and a digital accuracy self-test is performed in all current ranges. This versatile testing equipment provides reliable results for various maintenance requirements.
Constant current source: RPEO8
The RPEO8 constant current source, with its cascadable amplifiers of 8 kVA each, delivers reliable output performance at higher kilovolt amperes. The application range also includes further testing options, such as testing circuit breakers with various tripping mechanisms. The main functions and components remain identical to the RPEO4. Accuracy self-tests in all current ranges, short- and long-term measurements with constant current are possible. Additionally, this advanced product features database-based software for comprehensive test documentation. The system exemplifies our commitment to providing cutting-edge electrical testing equipment for modern power infrastructure needs.
