NKI – tension insulators
In our production is already for 9 months fully implemented the collaborative robot UR5 from the Danish company Universal Robots. Our company was also an exhibitor this year at the world’s largest energy fair in Hanover. The second application criterion to be met is a condition established by the effectiveness of system grounding. To ensure that the arrester’s capabilities will not be exceeded, the resources of the Thomas A.
Systems which permit earth faults to remain undetected or operate with one phase earthed for periods in excess of 24 hours will require the use of an arrester having a Uc continuous capability equal to the system maximum phase-to-phase voltage.
Email or password incorrect. The number of visitors and established business contacts is in line with expectations. The fair fulfilled our expectations. The disconnector will sense and disconnect the ground terminal in the unlikely event of arrester failure, preventing a permanent system short circuit.
A disconnector that has operated gives a visual indication of internal arrester damage and the need for arrester replacement. Table 1 in Catalog Section I provides a general application guide for the selection of the proper arrester rating for a given system voltage and system grounding configuration. Most contain our own built-in innovative patented solutions.
In the public tender “Incentives for research and development projects 2” we received grants 60909 “Development of a system for monitoring the functionality iiec surge arresters”.
These MOV disks have proven their reliability and protective abilities through years of in-service use. PKI – post insulators They have an innovative insulating head with integrated conductor clamping system. Also, such a fair allows us to understand and analyze the competition.

New Edition of IEC Published | In Compliance Magazine
This edition includes the following significant technical changes with respect to the previous edition: Give feedback about the content of this standard.
In addition to testing to evaluate the performance of the MO resistors, procedures for evaluating the performance of the EGLA series gaps have been introduced.
The voltage withstand capability application on ungrounded systems is 1. In addition, long term environmental testing has verified the lifetime superiority of UltraSIL silicone rubber when compared to other polymeric insulating materials. Edison Technical Center and their systems application engineers are available to make recommendations.
One must pay particular attention to systems having low coefficients of grounding, ungrounded systems and systems that are resonant grounded or that may become ungrounded under abnormal conditions of operation.
Jec UltraSIL housed surge arrester incorporates the industry recognized superior polymeric material — silicone rubber. Check video at https: Under some special system conditions, such as transformer energization using certain 60099 of connections and ferroresonance, higher voltages can be experienced by the arrester.
Manufacturing our own MOV disks allows strict quality control over the manufacturing process from start to finish. Using Metal Oxide Varistors MOVs having excellent electrical properties, these arresters provide superior overvoltage protection for MV distribution systems. The rating of an arrester is the uec power frequency line-to-ground voltage at which the arrester is designed to pass the IEC operating duty test.

The motive for the participation in the Hanover fair was to establish new contacts with potential partners or representatives of companies that market equipment for power systems.
