Production of resistance

From the year 2007 our company bought the rights to produce the high-voltage, oil-insulated resistance family from the East-Hungarian Electricity-Supplying Inc. and started the production of high-voltage appliances in the same year.

The appliances pertaining to this family are as follows:

FANOE (Earth-leakage current-booster high-voltage oil-insulated resistance)

Function, area of application:

In the mid-voltage compensated networks the function of the appliance is to increase the flowing current during lasting unipolar earth-leakage at the earth-leakage error-spot, to be detectable by the zero-ordinal excess current power fed by the lines of the current-switches, or if none such exist, then with the primary relay built in at each period.

HFE Av (Long-earthing high-voltage oil-insulated resistance)

Function, area of application:

The function of the long-earthing resistance is the star-point fixation of mid-voltage networks which are neither earthed directly, nor through a bend-alleviating coil.

PHE (Petersen tuner high-voltage oil-insulated resistance)

Function, area of application:

The ISZA type bend-alleviating coil regulating automatic was developed to automatically regulate the bend-alleviating coils. The system executes the measuring of the single network characteristics needed for the regulation by artificially generated voltage asymmetry. The Petersen Tuning Resistance is used to produce voltage asymmetry. The resistance joins the pre-set phase of the network through a unipolar disconnector. The switch built into the resistance is automatically switched on by ISZA for the period of regulation. The area of application of the PHE appliance is the complimentary appliance used for automatizing the compensation of earth-leakage of 20 kV free-cable and mixed networks.

ACSE (Asymmetry-reduction high-voltage oil-insulated resistance)

Function, area of application:

The increment of the deduction loss of the network by the order of kohm resistance, by being switched into a star-point. The area of application of the ACSE appliance is the 20 kV network.

The notations following the type names refer to the values of the main particular electrical characteristics of the appliance.

The main users of the above appliances are the various electricity-supplying companies.
