6 FAQs about [How to install the current transformer of the energy storage cabinet]

How do I connect a current transformer to a meter?

All current transformers are supplied with secondary terminals marked S1 and S2 which must be connected to the correct terminals on the meter. The meter will not register correctly if any of the CTs are connected incorrectly. The S1 terminal must be connected to the ‘current in‘ terminal for the appropriate phase on the meter.

What are the safety precautions when installing a current transformer?

Follow instructions carefully. DANGER: To reduce the risk of electric shock, always open or disconnect circuit from power-distribution system (or service) of building before installing or servicing current transformers. DANGER: Risk of electrocution! Do not install CTs when current flowing in the sensed circuit.

Can a current transformer be used with PRI metering?

Current transformers (CTs) must be installed by trained electricians or technicians. Only Instrument-type CTs with a low Safety Factor may be used with PRI metering. Protection-type CTs with a high Safety Factor must NOT be used. Dangerous voltages are likely to be present in the vicinity of current transformers.

What is a current transformer?

Current transformers are marked with the ratio between the maximum primary current and the maximum secondary current. For example a ‘600:5A’ CT produces a 5 A output signal when 600 A is flowing through the load. The primary rating must always be at least as large as the maximum current of the circuit to be monitored.

How many current transformers do I Need?

current transformer is required for each metered circuit, so a three-phase four-wire installation requires three current transformers, whereas a three-phase three-wire installation needs only two. Polarity must be observed when fitting current transformers.

What is a flexible coil current transformer (CT)?

SolarEdge offers use of a Flexible Coil Current Transformer (CT; also known as Rogowski coil) as an alternative to the split core CT. The flexible coil is useful for installation in the distribution panel when there is insufficient room for installation of a split core CT.
