Any maintenance and/or repair project generally follows a process which includes our:
AC technology has proved very effective in the field of generation, transmission and distribution of electrical energy.
Nevertheless, there are tasks which cannot be performed economically or with technical perfection by this method. For instance: economical power transmission over very long distances, power transmission via cables, power transmission between networks operating asynchronously or at different frequencies, input of additional power without increasing the short circuit ratio of the network concerned.
For all these tasks High Voltage Direct Current transmission is not only a relaistic technical and economical alternative to AC technology, but also the only possible transmission method.
Our staff has managed all aspects of engineering development, site planning and technical review of the physical and AC system control and protection sides of HVDC terminals and back-to-back converter stations.
HVDC/FACTS commissioning services offered by our specialists includes:
For generations, electric power system protection has been accomplished with the use of relays – electromechanical, solid-state, and microprocessor-based. We understand the inherent strengths and weaknesses of each. We also understand that relays, like other devices, have life cycles.
Nowadays, electromechanical and solid-state relays are being phased out, their strengths overshadowed by those of microprocessor-based relays. This is having a significant impact on the utilities operated by many industries.
Rest assured, we at HTS Consulting can handle relay replacement projects of any size or complexity. We know how to tackle every aspect of relay replacement flawlessly, too, from tracing wires to commissioning an entirely new relay system. What’s more, we can replace relays in your existing doors or provide a package that includes new doors manufactured to the specifications of your originals.
Our full range of relay replacement capabilities includes:
Replacing a SCADA system is a major project. Also, due to rapidly changing technology and business practices, it has to be carried out with increasing frequency. Now, instead of perhaps 15 years between projects in the past, there is less than a 10 year gap. This puts a lot of pressure on utility companies. The most important issues which are defining the needs of upgrading a SCADA system are:

GridEx built-in intelligence based on 30 years combined field experience in Protection Control with IEC 61850
Wavewin is used for fast line restoration, post-fault and disturbance analysis, dynamic relay testing, real time monitoring of evolving loads, contingency planning, and intelligent maintenance applications. Thanks to the powerful math on the recorded voltage and current signals, Wavewin is able to calculate the fault location and the fault resistance, giving valuable information to the relay engineer on how to optimize the relay settings with the experience gained by the transient recording of the power system faults. The software is a specialized, high-resolution graphic interface designed for universal management, display and analysis of digital fault records. Wavewin supports IEC 60255-24 / IEEE Std. C37.111 COMTRADE format (known also as COMTRADE 2013) and any previous COMTRADE format (1991 and 1999). It can of course open any format and save/convert in any format. Standard CSV format is also supported (which also allows for trending of periodic load measurements over long periods of time). Wavewin supports additionally a long and growing list of proprietary disturbance recorder file formats.
Wavewin sniffer is a transient disturbance recorder device that can be equipped with up to 8 sensors (current, voltage, temperature or humidity) sampled at 2340 Hz per channel.The data is continuously transmitted to a host computer over an Ethernet connection.The recording can be triggered manually or through threshold settings for the analog channels. The current sensor is a small, non-intrusive, clamp-on sensor based on Hall Effect to sense current flow through electric wires. It can detect AC and DC currents.The sensor has a curved mu-metal strip used for shielding against external magnetic fields and for amplifying internal fields. The sensor has a clothespin like enclosure and is capable of sensing microsecond transients (AC and DC) with a 2% accuracy range. The sensor uses a single RJ45 cable with 4 pins dedicated for both power and output signals.
The Device Manager is an advanced version of the Universal Viewer. It includes an extensive library of drivers for polling IEDs and retrieving their latest fault and disturbance records. It provides a database for configuring communication, storage, and reporting parameters. It complies with NERC PRC and CIP requirements. Each copy can poll up to 2,000 devices simultaneously. Both “report by exception” and “poll upon demand” functionality are supported and reports on communications integrity are also provided. The product is used for logging access and changing passwords on numerical relays and is equipped with an HMI used to populate single line diagrams with periodic readings including volts, amps, watts, VARs and status information. The Station Monitor is an advanced graphical interface that allows for users on the company's network to monitor all information polled from the devices configured in the device manager. Each station polled is displayed as a one-line diagram. The one-line diagram shows all device load information, circuit imbalances, circuit overloads, breaker status and more. It also allows for searching for station/device transient files, load data, event summaries and event histories.

The new genuine BALTO system, ranging from 3.000A up to 15.000A – in master/slave up to 30.000A - has been developed to generate very high DC test currents in order to realize functional tests on high speed DC circuit breakers. Those very high currents are injected on the main circuit of the circuit breakers.Moreover the whole circuitry can be checked, i.e. the current converters, the carrying bars and conductors, the connection points and the protection relays.STEVO Electric’s solution is the result of its field experience, acquired thru the close collaboration with the high speed DC circuit breakers’ manufacturers and the railroad companies. However the BALTO system can be used for any very high current demanding application.
