HWP – High Voltage General Protection Relay – Compliance Implementation

If you have a high-voltage delivery point with HVA metering, you have received or will receive a letter from ENEDIS regarding the compliance of your general HVA protection. This is due to the modification of the neutral regime, which will transition to compensated neutral in order to limit the homopolar fault current to 40 A.

For those affected subscribers, it is required to install a homopolar wattmetric protection (HWP). To achieve this, you will need:

– A protection relay of type SEPAM S48 E13 or equivalent, complying with standard C13 100.
– A 48 Vdc power supply.
– A set of connectors for SEPAM.
– A module with 10 logic inputs and 4 logic outputs.
– A CSH30 current transformer.
– 3 test boxes: for Current, Voltage, and Polarity.
– A kit for connecting to the HTA main circuit breaker.
– A low-voltage circuit breaker C60H-DC (for SEPAM power supply).

Our teams frequently perform this type of service, and we are at your disposal. Please note that this service needs to be carried out in collaboration with ENEDIS, as they are responsible for testing the HTA general protection relay at required thresholds. This operation is commonly referred to as “Essais C13 100”. We are also available to assist you with the necessary steps when dealing with ENEDIS.

The intervention will require your installations to be powered down, and the average duration of the process is around 6 hours.
