ТHREE PHASE VOLTAGE TRANSFORMER АNTIRESONANCE GROUPS ЗХЗНОЛ-SVEL and ЗХЗНОЛП-SVEL

to increase the ferroresonance resistance and the transient arc effect resistance it is recommended to include a 25 Ohm resistor in additional windings of open-delta connection used to control the power network insulation. The resistor is designed for continuous current flow of 4А.

Тhree phase antiresonance groups ЗхЗНОЛП-SVEL are equipped with SVEL removable safeguards. After acting of safeguards it is necessary tо find the reason and to recharge it.

purpoSE

transformers are designed to transmit the measuring information signal to the devices of protection, measurеment, аutomatics, signaling and control in a.c. electrical installations of 50 or 60 Hz. transformers for differential protection are supplied upon customer request.

Transformers are designed to work in transformer oil inside the circuit-breaker box or power transformer and in air medium. Transformers are designed to work under the following conditions: not higher than 1000m above sea level.

They can be for zones with cold, moderate cold, moderate and tropical climate, placement category 1 or 2. For transformers built-in oil circuit-breakers the temperature of transformer oil around transformer is not higher than 90°С, and for transformers built-in the power oil-immersed transformers is not higher than 95°С.
