Problem
Compensation cabinet problem - how to choose the fuse / knife switch?

Configured according to the capacitor capacity of 2 times, for example: 300Kvar capacitor cabinet with 600A knife melt switch or knife switch.

Compensation cabinet problem - Is the primary transformer output grounded?

need. The secondary side of the current transformer is grounded to protect the grounding, preventing primary insulation breakdown, and the primary voltage is connected to the secondary circuit, causing high-voltage safety accidents.

Product use problem - In the case of a controller, after the secondary connection is completed, can the last socket be empty?

All products can be connected together through the communication connection socket, and whether the socket is empty or not has no effect.

High Altitude Questions - Can products at high altitudes be made?

Anti-harmonic products are mainly used in applications where the total capacity of non-linear loads such as chemicals, building materials and coal is greater than 15% of transformer capacity.

Anti-harmonic harmonic problem - product selection, common product, anti-harmonic 7% anti-harmonic 14%?

The total capacity of the nonlinear load is greater than 14% of the transformer capacity by 14%, and the total capacity of the non-linear load is 7% when the transformer capacity is 15%~50%. Harmonics mainly used 14% for 3 times. Use 7% of the main 5 or more.

Smart Capacitor Problem - Why can I use a capacitor with a smart capacitor without an external lamp?

The function of the external indicator light is to indicate the switching state of the capacitor. This function is already available in our controller and status indicator. However, most electric power bureaus must be installed when they are required to be installed.

Wiring current problem - Can current sampling be commutated? What should I change?

The total compensation controller current sampling is phase B, the voltage is connected to UA, UC phase, if the current is phase A, the voltage is connected to UB, UC phase.

Controller problem - how to connect the controller wiring?

9 series, a total of voltage connection UA, UC current mining B phase, communication 485. Mixed voltage connection UA, UB, UC, UN, current mining 3 phase, communication 485. 8 series, a total of voltage connection UA, UB, UC , UN, voltage A phase, communication 485. Mixed compensation, mixed voltage connection UA, UB, UC, UN, current acquisition 3 phase, communication 485.

Debug parameter question - Does the ID of the smart capacitor need to be set?

ID address does not need to be set, our company's products are automatically assigned ID address.

Debug parameter question - Does the controller have to set the ratio?

The 9 series controller does not need to be set, and the 8 series needs to set the ratio.

Debug parameter problems - capacitors and controllers We debug to set those parameters?

The large controller should set the current ratio. In order to facilitate the user to use our products, other settings do not need to be made. Only need to be powered on to confirm the communication connection, and then confirm the correct voltage and current phase.
