SHR - THREE-PHASE SHUNT REACTOR Three-phase shunt for compensation of reactive power and stopping of the electric arc of one-phase short circuit. Maximal allowed time of the one-phase short circuit depends on the particular customer requirements and varies between 5 minutes and 8 hours. Applicable in case of overhead lines and power cables. Possible manufacturing with and without regulation.

All technical characteristics can be adjusted to the particular customer s needs. Technical characteristics of SHR-7,5: Standard: IEC 60076-6 Rated reactive Power (kvar): 87 178 Rated Voltage (kv): 10; 20,5 Highest voltage level of equipment (kv): 12; 24 Connection: YN Reactive Current per phase (A): 1.67 5 Compensative fault Current (A): 5 15 R/X (%): < 1.25 X linearity (%): <2 Fault duration (min): 120 Cooling: ONAN Temperature class: A Frequency (Hz): 50 SNRO: 57 090 00 Terminations: a) Open type bushings (standard solution) b) Plug-in type bushings (optional solution) SHR - THREE-PHASE SHUNT REACTOR PDF BROCHURE IS AVAILABLE ON THE LINK

SUBc GROUNDING REACTOR WITH PETERSEN COIL Subcomp (SUBc) is a grounding reactor with winding in Z-connection and with variable impedance Petersen coil, both of which are placed in the same tank. In normal operation, Subcomp is characterized by a very small magnetizing current. During a one-phase fault, the fault current is limited by the Petersen coil which is connected to the star-point of the reactor s Z-connection winding. The duration of the fault is usually limited to 300 seconds. Some of the notable technical characteristics of Subcomp are R/X < 2,5% and Linearity (diff) <1,5%.

Technical characteristics of SUBc-20,5kV; 25A-50A: Rated Voltage (kv): 20,5 Highest voltage level of equipment (kv): 24 Connection: ZN Reactive Current per phase (A): 25 50 No-load losses (W): 320 Impedance [Ω]: 474 237 R/X (%): < 2.5 X linearity (%): <1.5 Fault duration (min): 5 Cooling: ONAN Temperature class: A Frequency (Hz): 50 Standard: IEC 60076-6 SNRO: 57090 00 Terminations: Accordance with: EN 50180, EN 50386, EN 5038 a) Open type bushings (standard solution) b) Plug-in type bushings (optional solution) SUBc - GROUNDING REACTOR WITH PETERSON COIL PDF BROCHURE IS AVAILABLE ON THE LINK

TIM TPH CNT GROUNDING TRANSFORMERS WITH PETERSEN COILS Grounding transformer with Petersen coil is a transformer with ZNzn0 (or ZNyn11+d) connection and variable impedance. The high-voltage side of the transformer is characterized by low zero-sequence impedance (less than 30 ohm). On the low-voltage side (410V) the zn or yn+d connection allows exploitation of three-phase and onephase voltage. Compensative current is adjustable in 5 steps. The allowed time of a one-phase fault is up to 120 minutes.

All technical characteristics can be adjusted to the particular customer s needs. Remark: In comparison to the TIM-TPH Series, the CNT Series involve the maximal duration of the fault which is 5 minutes (instead of 120 minutes of TIM-TPH) and ZNyn11+d connection (instead of ZNzn0). General technical characteristics of TIM-TPH-CNT series: Rated Power (kvar): 50, 100, 200, 315, 500 Rated High Voltage (kv): 10; 11; 20,5; 22; 33 Rated Low Voltage (kv): 0,410; 0,420 Highest voltage level of equipment (kv): 12; 24; 36 Connection: ZNzn0 (or ZNyn11 +d) Compensative fault Current (A): 5 15 R/X (%): < 2.5 Total variation Zo (%): <2 Fault duration (min): 120 (or 5) Cooling: ONAN Temperature class: A Frequency (Hz): 50 Standard: IEC 60076-6 SNRO: 57090 00 TIM - TPH - CNT GROUNDING TRANSFORMER WITH PETERSON COIL PDF BROCHURE IS AVAILABLE ON THE LINK
