DATA SHEET VOLTAGE INDICATOR TYPE SPA-ES panel-mounted General Description The voltage indicator type SPA-ES can be used in medium voltage networks with a rated voltage of 5 kV to 36 kV. The function of the device is a permanent indication of the voltage status of the monitored conductors. The indication of the voltage is done by a permanent blinking of one LED per phase. The type SPA-ES is connected to the capacitive pickup of a bushing or insulator. The display unit has to be adapted to the capacitance of the bushing or insulator. For the operation of the display device, an auxiliary power supply figure 1 - Housing of indication unit is required. If the voltage is present, one LED per conductor is blinking. If the voltage of a conductor drops, the respective LED stops blinking. Additionally the device is equipped with relays to remotely indicate the voltage status via change-over contacts. It is possible to select the characteristics of the relay contacts (factory pre-set). If the device is equipped with three relays the voltage status of each phase can be remotely indicated. If one or two relays are equipped the remote indication of the voltage status is bundled. It can be selected whether the relays operate if there is a voltage drop on one phase or if there is a voltage drop on all phases. Features and Options Power supply options: Remote indication options: a) External power supply of 12V DC - 110V DC b) External power supply of 230V AC a) One/Two relays for indication of no voltage on all phases b) One/Two relays for indication of no voltage on one phase c) Three relays for indication of no voltage for each phase connection to bushing or insulator L1 connection to bushing or insulator L2 connection to bushing or insulator L3 1 or 2 relay version: not connected 3 relay version: SCADA change-over contact L1 figure 2 - Connectors (2 relay version) Connector 10 - 12: 1 or 2 relay version: SCADA change-over contact L1, L2 and L3 3 relay version: SCADA change-over contact L2 Connector 13 - 15: 1 relay version: not connected 2 relay version: SCADA change-over contact L1, L2 and L3 3 Relais: SCADA change-over contact L3 Connector 16 - 17: External power supply ELEKTRO-MECHANIK EM GMBH Ringstr. 4 - D-42553 Velbert / Germany Tel: +49 2053 422890 - Fax: +49 2053 422899 www.emg-ger.com
