Inspection during Installation The transformer should be carefully inspected for any damage due to handling after receipt. The nameplate rating on the unit should be checked against the job specifications to ensure installation of the correct transformer. The transformer should be connected only as described on its nameplate.
The reactive power absorbed by a transformer cannot be neglected, and can amount to (about) 5% of the transformer rating when supplying its full load. Compensation can be provided by a bank of capacitors. In transformers, reactive power is absorbed by both shunt (magnetizing) and series (leakage flux) reactances.
current transformer before installing the current transformer • Terminals are brass with 8–32 threads. Current transformers are metering class. Accuracy is 1% at 25 VA burden for TX2, TX4, and TXSUM-2. Accuracy is 1% at 30 VA for TX5 • The CT should always be installed upstream of the loads and capacitor bank

When the load does not vary, global compensation is suitable and provides the best savings and performance compromise. The capacitor bank is connected upstream of the HV/lV transformer.
Segment (or group) installation Segment installation of capacitors assumes compensation of a loads segment supplied by the same switchgear. Capacitor bank is usually controlled by the microprocessor based device called power factor regulator. Beside, segment installation practice demands protection for capacitor banks.
Insert the two 3/4-in. bolts through the holes, using washers and lockwashers as needed. Thread the nuts onto the bolts but do not tighten. Using the lifting eyes on the capacitor bank frame, lift the capacitor bank, positioning it at the pole so that the bolts can slip into the slots on the capacitor bank pole-mounting bracket. (Figure 3)
The capacitor bank is connected in the distribution board at the head of a circuit or a group of circuits, or better still in the distribution switchboard of the sector concerned, and supplies the reactive energy required by one sector of the installation. A large part of the installation is thus freed from the consumption of reactive power.
